ATS-Friendly Resume Format: What an ATS Can Read (2026)

Many guides about the applicant tracking system (ATS) repeat numbers that have no source. For this guide, we opened the help pages of ATS vendors and read them. We also counted the words in 9,403 job descriptions that Careerfornia users pasted.

Each fact about an ATS product has a link to its source. The other points are plain format advice, and we say so.

What is an ATS and what does it do with your resume?

An ATS is the software that a company uses to collect and organize job applications. It does three things with your resume:

1. It stores the application. Your resume and your answers to the application form go into one record.
2. It parses the file. The software reads the text and copies it into fields, such as name, email, and job title. If the parse fails in Greenhouse, the recruiter must type your details into the fields by hand.
3. It lets recruiters search and filter. For example, a Greenhouse user can search resumes for keywords.

Large companies almost always use one. In its 2026 report, Jobscan detected an ATS for 97.4% of Fortune 500 companies. That is 487 of 500 companies.

The ATS is the place where the recruiter works. The next section shows who makes the decision.

Does an ATS reject resumes automatically?

We found no evidence that an ATS rejects most resumes automatically. The automatic rejection that vendors document comes from your answers in the application form.

Where does the "75% of resumes are rejected" claim come from?

Many articles say that an ATS rejects 75% of resumes before a person sees them. We searched for a primary study and could not find one.

HR consultant Christine Assaf also looked for the origin. HiringThing reports that she traced the number to Preptel, a job-services company that closed in 2013. She found no study behind it. Do not rely on this number.

There is a small study in the other direction. Enhancv interviewed 25 US recruiters. 23 of them said their systems do not auto-reject resumes for formatting, content, or design. The sample is small, and Enhancv sells resume tools. Read it as a signal, not as proof.

What does happen to your application?

Employers use these tools. Harvard Business School researchers asked employers that used a recruitment management system. More than 90 percent relied on it for a first cut or to rank applicants.

Each employer sets up its ATS in a different way. You cannot see the setup. You can control two things: a file that parses correctly, and the words in it.

What resume format can an ATS read?

Use one column of real text with standard headings. This is the base of an ATS-friendly resume format in 2026.

Greenhouse publishes a list of formats that can cause a failed or partial parse. The list includes graphics, tables, headers and footers, a columned layout, and resumes uploaded as an image.

Other ATS products use other parsers. We did not test each one. The table below is general advice.

PDF or DOCX: which file should you send?

Send the file type that the application form asks for. If the form accepts both, a text-based PDF or a DOCX is usually fine.

People often ask if an ATS can read a PDF. Here is what we can support with a source:

• Greenhouse lists .doc, .docx, .pdf, .rtf, and .txt as supported formats for resumes.
• Greenhouse says that it cannot parse resumes larger than 2.5MB.
• We found no vendor page that says a PDF parses worse than a DOCX. Many articles claim it. We cannot confirm it.

Use these rules:

1. If the form names a file type, send that type. If it asks for DOCX, send DOCX.
2. Make the PDF with "Export" or "Save as PDF" in a document editor. Do not print and scan the page.
3. Keep the file small. Remove photos and large images.

How do you check that an ATS can read your resume?

Copy all the text from your PDF and paste it into a plain text editor. This test is free and takes two minutes.

Test 1: the plain text test

1. Open the PDF of your resume.
2. Select all the text and copy it.
3. Paste it into a plain text editor, such as Notepad.
4. Read the result from top to bottom.

If you cannot select the text, the file is an image. Export it again from the document editor.

This test does not copy the parser of a specific ATS. It shows which text is in the file, and in which order.

Test 2: the autofill test

Some application forms fill their fields from your resume after you upload it. Look at each field: name, employer, job title, and dates. If a field is wrong, correct it in the form. Then repair that part of your resume.

Do keywords matter for an ATS?

Yes. Keywords matter when a recruiter searches the ATS and when a match feature compares your resume to the job. The sources in the table above show both.

Use the exact words of the job description. If it says "Power BI", do not write "PBI". Add a keyword only when it is true for you.

Job descriptions are short, so each keyword is important. The median job description in our data has 411 words. SQL is in 81% of 1,265 data analyst job descriptions.

To find the keywords of one job, read how to tailor your resume to a job description. For the keywords of a role, see the guides for data analysts, software engineers, and data engineers.

What do job descriptions contain that an ATS can filter on?

Job descriptions state conditions such as sponsorship, work authorization, citizenship, and work location. Application forms often ask about the same conditions as yes or no questions.

We counted these conditions in 9,403 job descriptions:

• 6.7% use the word "sponsor".
• 4.0% ask for work authorization.
• 5.2% ask for citizenship or a clearance.
• 15% give a pay range.

People search for how to get past an ATS. No format changes the result of a knockout question. Read the job description for these conditions before you apply, and answer each question truthfully. If you need sponsorship, read our resume guide for international students.

What does a simple ATS-friendly resume layout look like?

It is one column with five standard sections in this order. If you have less than two years of work, put Education above Experience.

FIRST NAME LAST NAME
City, State | Phone | Email | LinkedIn URL

SUMMARY
Two or three lines: job title, years of experience, top three tools

What mistakes break parsing?

Avoid these five layout choices. Each one can hide text or change its order.

• Two columns. A parser can read across the two columns and mix the lines. Use one column.
• Icons for contact information. An icon is an image, not text. Write the words: "Email" and "Phone".
• Skills as rating bars or graphics. A bar has no text for a recruiter search to find. Write the skill names.
• Dates in odd formats. Use the month and the year in the same format for each job.
• Creative section names. A heading such as "Where I have been" is not clear. Write "Experience".

How did we get our numbers?

We used the job descriptions that Careerfornia users pasted from September 2025 to October 2026. We removed duplicates. That left 9,403 different job descriptions. For each condition or keyword, we counted the job descriptions that contain it.

The sample has limits. It is the jobs that our users applied to. Most are data and software jobs in the United States. It is not a sample of all jobs.

For the statements about ATS products, we opened each linked page on October 12, 2026. Vendors change their products, so open the links for the current text. We did not test resumes in each ATS. We cannot promise a result from any format.
