You can spend hours crafting the perfect resume and still get filtered out if the ATS cannot parse it correctly. An incompatible format means your years of experience, your keywords, and your accomplishments might never make it into the system's database. Checking for compatibility before you apply takes less than ten minutes and can dramatically improve your callback rate. This guide shows you exactly how to do it.
Try It FreeSelect all the text (Ctrl+A or Cmd+A), then copy and paste it into a plain text editor like Notepad on Windows or TextEdit in plain text mode on Mac. Read through the result carefully. Any content that disappeared - contact details, a skills section, text inside a table cell, content in a header or footer - will also be invisible or scrambled for the ATS. Fix anything that is missing before you continue.
ATS parsers frequently skip headers and footers entirely, which means your contact information may not be extracted. Move your contact block into the first section of the main document body. Place your name on one line, then your email, phone, and LinkedIn URL on the next line, separated by pipes or vertical bars.
ATS systems recognize standard headings and use them to categorize your information. Replace any creative labels with standard ones: use 'Work Experience' not 'Career Journey,' use 'Education' not 'Academic Background,' use 'Skills' not 'What I Bring.' If you have a custom section for volunteer work or projects, label it clearly as 'Volunteer Experience' or 'Projects' so the parser can classify the content.
The tool will show you a parsed preview of your resume - the version the ATS actually sees - and a keyword match score. Look for truncated text, missing sections, or garbled formatting in the parsed view. These are the exact issues that would cause an ATS to score you lower than your qualifications warrant. Fix each issue and re-run the test.
Stick to standard fonts: Arial, Calibri, Georgia, or Times New Roman in 10-12pt.
If the job posting does not specify a format, .docx is the safest choice for maximum ATS compatibility. If you are submitting a PDF, make sure it is a 'selectable' PDF - one where you can click and drag to highlight the text - not a scanned image PDF, which is unreadable by all ATS systems. In Word, use File > Save As and choose .docx. In Google Docs, use File > Download > Microsoft Word.
Check your resume against any job description in under 60 seconds.
Add to Chrome for FreeIf a company has an online application portal - even a simple form on their website where you upload a resume - they almost certainly use an ATS to manage applications. Large companies uniformly use them. Mid-size companies and rapidly growing startups usually do too. The only typical exception is very small companies and startups still managing email applications manually. When in doubt, optimize for ATS regardless.
Most two-column resume formats built with tables or columns fail to parse correctly. The ATS reads left to right across the full page width, which means it will interleave text from your left and right columns in a scrambled order - for example mixing your job title from the left column with your dates from the right column into a single sentence. Single-column formats are far more reliable. If you want visual appeal, save the designed version for situations where you hand your resume to someone directly.
You only need to check ATS compatibility once for a given resume version. Once you have confirmed your formatting passes the parse test and your base resume is ATS-compatible, you can focus future checks on keyword matching for each specific role. If you make significant formatting changes to your template - adding a new section, changing the layout - run a fresh compatibility check before your next batch of applications.
