How do I check if my resume is ATS friendly?

The nearest check I can offer is AceDraft's ATS scan , which reads one PDF resume against one job description you paste in. It gives a score out of 100 and lists of matched and missing keywords, with 15 scans a day signed out and no cap once you sign in. In the 14 September 2026 build only the Job Title Alignment row scored, so the headline can read a false 100 or a false 0 depending on whether you fill in the optional job-title field. Both keyword lists came back empty on my own scans. There's no pass mark either, because no score is linked to any hiring outcome. It also can't tell you what Workday, Greenhouse, Lever, Taleo or iCIMS would do with the same file, so check in presale page for our demo resume and you can verify our claims in the opensource tool we have mentioned there.

How do I make my resume ATS friendly?

Use one column with no tables for layout, and borrow the job posting's own words where they're true for you. You can write it in AceDraft's guest editor without making an account, and the guest editor walkthrough goes through it step by step. Your draft lives only in that browser's storage, so clearing site data or switching browsers loses it. Editing, the preview and a plain-text ATS PDF cost nothing and need no account. The save-and-export walkthrough shows that screen, and neither option on it gives you a Word file. I haven't put any AceDraft layout through a named ATS, so I can't tell you how one reads it.

How do I tailor my resume to a job description?

Start from a resume you like and change the wording toward one posting, keeping only what's true for you. In AceDraft that's Branch for a New Job : you give it a job title, a company name and the posting, and it makes a new, separate resume aimed at that one role while the original stays untouched. It starts from a resume already saved in your account, so it's no use until you have one. I read every line it hands back before I'd send it, because the rewrite can only use what's already in your resume or the posting. Anything you did and never wrote down stays missing.

What is a good ATS score?

There isn't a universal one. I publish no threshold for AceDraft's scan , because no score it gives is linked to any hiring outcome. My walkthrough of the AceDraft scan has the row-by-row detail. In the 14 September 2026 build only Job Title Alignment scores, so the headline out of 100 can read a false 100 or a false 0.

Is AceDraft's paid export better than the free one?

Only if you want your wording changed. The free download gives you the resume exactly as you wrote it, in the template you picked, with no watermark and no account. The paid card on that same screen lists four things: a rewrite of your content for recruiters and ATS, a full keyword-gap report, a polished PDF, and a copy kept in your account history. You sign in first and pay once per export, with no subscription. As of 28 September 2026 the Founding presale at sale.acedraft.app sells export credits that never expire. If your resume already says what you want, the free file is all you need. I haven't tested how any ATS reads either file, and I have no data showing that either one leads to an interview.

Can AceDraft answer screening questions for me?

No. AceDraft has no feature that reads or answers the screening questions on an employer's application form, and as of 28 September 2026 nothing in its code handles them. Those questions are the trigger on the Greenhouse auto-reject page I cited in the section on whether an ATS automatically rejects your resume, so answer them yourself, slowly and truthfully. That part of the application is outside anything AceDraft does.

ATS Myths, Checked: What an ATS Does to Your Resume

I build AceDraft, a resume builder with an ATS scanner inside it. So I have a stake in you believing ATS software matters, and you should read this post knowing that.

The second thing to know: I have not submitted a resume through Workday, Greenhouse, Lever, Taleo, iCIMS or any other named ATS. The presale page does offer a demo resume and the job description it was built against. You can test both in ATS Screener, a free open-source screener by an independent developer that simulates those systems and isn't affiliated with them, so check in presale page for our demo resume and you can verify our claims in the opensource tool we have mentioned there. Every claim below about how a real ATS behaves comes from a public source, with its publisher and date next to it. Where I couldn't find a source, I say so and stop.

Sources were checked on 27 and 28 September 2026.

Key takeaways

I couldn't find any published study behind the famous "most resumes get auto-rejected" number. Neither could the HR writer who traced it in 2020.
Greenhouse's own help page describes auto-reject as a rule the employer sets up, triggered by answers to screening questions. That's one product.
Two risks I'd actually spend time on: a layout that scrambles when software pulls the text out, and wording that doesn't match the job post.
Limitation: I haven't tested any named ATS, and AceDraft's own scanner is partly unbuilt. Anything here about a specific product is what that vendor says, not what I saw.

Where does the "most resumes are rejected by ATS" claim come from?

I can't find a source for it that shows how the number was worked out. The version you've probably seen says 75% of resumes are rejected by an ATS before a human reads them. I'm naming it once so you know which claim this is. I'm not repeating it as true.

The earliest trail I could find runs to a resume-service firm called Preptel and a 2012-era claim.

In a post on HRTact by Christine Assaf (5 October 2020), she followed the figure back through articles on TopResume, Forbes, Zipjob, CIO.com and Workopolis. She found no citation to research in any of them. The trail ended at Preptel, which she says went out of business in August 2013. She also spent an hour searching academic databases and found little.

I searched for Preptel's study myself, expecting a dull PDF with a methods section. I didn't find one, and I didn't find Preptel's method written down anywhere. It was a short search, so read it as a limit of what I looked at. If you hold the original, I'd like to see it.

A later post from Uncharted Career (4 July 2026) tells the same story and adds that Preptel never published a study. It doesn't link to any Preptel material. So I read it as a summary of Assaf's work, and I don't count it as a second, independent check.

An article in The Conversation (5 July 2026) by two researchers, Leda Salazar de Leon of Mount Royal University and Mehnaz Rafi of the University of Calgary's Haskayne School of Business, tells the same story. It says the figure "originated from a 2012 sales pitch by Preptel," a resume company that went out of business the following year, and that "no methodology was ever published."

Like Uncharted Career, it doesn't link any Preptel material. So I read it as a secondary source that agrees with Assaf. It doesn't settle where the number began. I'd swap all three write-ups for one copy of the original pitch.

Here's where that leaves the number. It has no published evidence behind it that I can find. That doesn't prove the opposite is true. It means nobody I can find has shown the work, and I'd stop quoting it until someone does.

Does an ATS automatically reject your resume?

Some can, but the one vendor page I checked describes auto-reject as a rule the employer switches on, triggered by answers to questions. It doesn't describe software reading your resume and deciding you're out.

First, what an ATS is for. An applicant tracking system is the software a company uses to keep track of who applied for which job, and where each person is in the hiring process. Think of a shared inbox with a filing cabinet bolted on. If you want the plain version of what AceDraft covers on this, it's in AceDraft's ATS FAQ.

Now the rejecting part. Greenhouse's help page on auto-reject (last updated 30 January 2026) says it fires based on an applicant's answer to a question. The supported question types are Yes/No, single-select and multi-select. It's only available on Greenhouse's Plus and Pro plans. The page doesn't mention resume text as a trigger.

People usually call these knockout questions. Here's a made-up example: "Can you work on-site in Pune?" If an employer set up a rule on that question, answering no could get you rejected by the system before anyone looks.

A stock photo of a blank paper form with Yes/No tick boxes. Online application questions look different, and this shows no ATS.

I found one survey on this, and it comes with a catch. Enhancv's post on whether an ATS rejects your resume (published 3 November 2025, updated 24 September 2026) reports interviews with 25 US recruiters in September and October 2025. Of those 25, 23 said their systems don't auto-reject resumes for formatting, content or design.

Enhancv also says every recruiter it interviewed used knockout questions where their system had them. It describes these as yes/no eligibility checks, like work authorisation, a required licence or location. A team can send a failed answer to a person, it says, or flip a setting that sends it straight to reject. That matches what Greenhouse's help page describes: the auto-reject trigger is an answer to a question.

Now the catch. Twenty-five recruiters is a small sample, and Enhancv sells resume tools, so it has the same stake in this topic that I admitted to in my first line. I read the survey as what those 25 people told one company. It doesn't tell me what recruiters in general do.

Assaf's 2020 headline makes the wider argument bluntly: "Your job application was rejected by a human, not a computer." That's her conclusion. I haven't checked it across employers.

And here's what I can't tell you. Greenhouse's page is one product's documentation. It says nothing about Workday, Lever, Taleo or iCIMS. I've also never seen any employer's settings, so I don't know how many turn auto-reject on, or what they ask.

Do PDFs fail in an ATS?

A PDF resume doesn't fail at the upload step in Greenhouse, the one ATS whose format list I checked. Its help page on supported formats (last updated 19 August 2026) lists .doc, .docx, .pdf, .rtf and .txt uploads, up to 100 MB.

That answers whether it will take your PDF. It doesn't answer whether it reads every layout inside the PDF correctly. The page doesn't cover that at all.

I haven't tested how any ATS reads a PDF. So I won't tell you PDFs are always safe. I won't tell you some kind of PDF always fails, either, because I don't have a source for that.

What I'd do: if a job posting or application form asks for a specific file type, send that one. It's the only rule in this section I'd call certain, because the employer told you.

Are tables and columns safe in an ATS?

Tables and columns may not be safe in an ATS, but the risk is a scrambled read of your resume, not an automatic rejection. A layout that scrambles when software pulls the text out is the first of the two risks I'd actually worry about. I call it mis-parsing.

Parsing is when software pulls the text out of your file and sorts it into fields like name, job title and dates. If a two-column layout comes out with the lines shuffled together, the parsed version a recruiter sees can read like two conversations happening at once.

Jobscan's post on tables and columns (24 September 2026) says most ATS parsers read in a straight line, and that multi-column layouts and complex tables frequently scramble the parse. It shows one example from Lever.

It doesn't say how it tested or which products it looked at. And Jobscan sells a resume checker, which is a bias I recognise easily, since I have the same one. So I treat it as a reasonable warning and nothing more precise than that. I haven't tested this myself.

AceDraft is built on the view that mis-parsing is a real risk. That's my stance as the person who built it. It isn't a measured finding.

The myth here is the confident version: "tables and columns are fine now." I can't prove they break in any product I can name. I also can't find anyone who has shown they're fine. A one-column layout takes the question off the table, if you'll forgive the pun.

Does keyword stuffing or hidden white text beat an ATS?

I haven't seen any evidence that it does, and there's a plain reason it can backfire. The trick is to paste the job description into your resume in white text, so software reads it and people don't.

Jobscan's post on keyword stuffing (14 November 2024) says hidden keyword text is easy to spot once the resume has been parsed, and shows one screenshot from Taleo. It also says recruiters resent it. It gives no method.

Here's what I can say from how documents work, no ATS needed. Colour is only a display setting. The text is still text. Anyone who presses select-all, or pastes your resume into a plain box, sees the white words sitting right there. You'd be betting that nobody does the most ordinary thing people do with documents.

I haven't tested any ATS with hidden text, and I won't claim a named product catches it.

Keywords do matter in one way, though, and it's the second risk I'd worry about. I call it under-ranking. If your resume calls a skill one thing and the job post calls it another, a recruiter searching for the job post's word may not find you. That's AceDraft's working view, not a tested result. The fix it points to is using the job description's actual words where they're true for you. Repeating them over and over doesn't add anything I can point to.

Is an ATS "score" a real pass mark?

No. A score from any resume tool is that tool's own number, worked out by that tool's own rules. No employer set it as a pass mark.

That includes mine. As of 27 September 2026, AceDraft's scanner scores only one of its five rows, and the headline score can read a false 100/100 or 0/100 depending on whether you fill in the optional job-title field. It doesn't predict any ATS outcome.

The details are in how the AceDraft scan reads. If you try the AceDraft ATS analysis page, keep that limitation next to the number. I'd rather you hear it from me here than find it by accident.

What should you fix, and what can you stop worrying about?

Fix the three things under "Worth fixing", and drop the number. That's the whole verdict.

The Conversation article I cited above (5 July 2026) lands somewhere close. Its authors write that "hiring decisions are ultimately made by people," and suggest you "put the time you'd spend on template optimization into one good conversation with someone in your field." I build a template-based resume tool, so that advice costs me something to repeat. I think they're right anyway.

Worth fixing

A layout that parses cleanly. One column, and no tables used for layout.
Your wording. Where a skill in the job description is true for you, use the same words the posting uses.
The screening questions on the application form. Greenhouse's help page documents these as its auto-reject trigger, so read them slowly.

Safe to stop worrying about

The rejection-rate number. I can't find the evidence behind it.
Any tool's score as a pass mark, AceDraft's included.
Whether a PDF will be accepted, when the form says PDF is fine.

Use this if you're applying through online forms and someone told you a robot bins most resumes before a person sees them.

Skip this if you need to know how Workday, iCIMS or another named ATS handles your exact file. I can't tell you, and none of the sources above published a method for testing it.

What haven't I tested?

Quite a lot, and I'd rather list it than let you assume.

Any named ATS. I have not put a resume through Workday, Greenhouse, Lever, Taleo or iCIMS. The demo resume on the presale page can be checked in ATS Screener, which simulates those systems and isn't affiliated with any of them, so check in presale page for our demo resume and you can verify our claims in the opensource tool we have mentioned there.
Who first said the rejection number. The trail stops at Preptel, and I haven't seen Preptel's own material.
Whether tables and columns break in a product I can name. My only source is a vendor that doesn't publish its method.
Hidden text against any real system.
How employers set up auto-reject. I can read one vendor's help page. I can't see anyone's settings.
Most of my own scanner. The Hard Skills, Soft Skills, Formatting and Content Quality rows don't score yet.
