Check if your resume will pass Applicant Tracking Systems. Get your ATS score, keyword analysis, and actionable suggestions to improve your resume.
The ATS checker validates your resume against the parsing behavior of common Applicant Tracking Systems (Workday, Greenhouse, Lever, Taleo) and surfaces the structural issues that block a typical ATS from reading the file correctly. It scores parseability, structure, keyword density against a target JD, and red flags (graphics, multi-column layouts, header/footer text). The score is directional — it is calibrated against public behavior of common parsers but real systems vary. Use it to catch obvious blockers (tables, images, missing standard sections) rather than as a definitive pass/fail. A high ATS score gets you read; it does not get you interviewed.
Use cases
Pre-flight check before submitting an application. Run the checker on the version you are about to submit. If parseability scores below 80, fix the structural issues before sending — most candidates assume their resume is ATS-friendly until they actually test it.
Diagnosing why a polished resume gets no responses. Beautiful resumes with two-column layouts, custom fonts, and embedded icons frequently score below 60. The visual appeal that wows humans confuses parsers. The checker surfaces exactly which elements are breaking parsing.
Comparing two resume versions side by side. Run version A, note the score breakdown. Run version B. Compare. The tool shows whether your edit moved you in the right direction or accidentally introduced a new structural issue.
Validating a resume from a non-ATS-friendly designer. Designer resumes often look professional but parse poorly. Before paying a designer, ask for an ATS-friendly version too. Or run the design through the checker first to confirm it parses cleanly.
How it works
Upload PDF or paste resume text. PDF parsing checks both the visual layout and underlying text structure. Pasted text checks structure only. PDF input is more thorough; pasted text is faster.
Review the parseability score and structural issues. The score reflects whether a typical ATS can read your sections, contact info, dates, and skills. Score below 80 indicates issues to fix before submitting.
Fix structural blockers. Replace tables and multi-column layouts with single-column flow. Move contact info to the body, not header/footer. Use standard section headings. Remove custom fonts and embedded icons.
Add a target JD for keyword scoring. Paste the JD to score keyword coverage. Add missing must-have keywords by rewriting bullets — only ones you can honestly support.
Re-check and download the optimized version. Re-run the check; aim for 90+ on parseability and 80%+ on JD keywords. Save the optimized version specifically for this role.
Examples
A candidate applying to 50 roles with a polished two-column resume. Original scores 58 on parseability. Converts to single-column, fixes section headings. Re-score: 92. Application response rate jumps from 4% to 18% with the same content.
A senior engineer with a "creative" PDF. Custom font and embedded icons cause parseability to score 45. Replaces font with system default and removes icons. New score: 88. Recruiter callbacks resume within two weeks.
Frequently asked questions
What is an ATS and why does my resume need to pass it?
An Applicant Tracking System is software that companies use to filter resumes before a recruiter reads them. It parses your resume into structured fields. If parsing fails (because of tables, images, or odd formatting), your resume can be discarded before any human sees it.
What does the ATS checker score?
It scores parseability (can a typical ATS read the file), structure (clear section headings, contact info up top, dates in standard format), keyword density against a job description, and red flags (graphics, columns, headers/footers).
How accurate is the score versus real ATS systems?
It is calibrated against public behavior of common ATS parsers (Workday, Greenhouse, Lever, Taleo). It is directional, not exact — actual systems vary. Use it to catch obvious blockers, then test by submitting to a real ATS and reviewing the parsed preview if available.
My resume scored 90+ but I am still not getting interviews — why?
ATS is one filter; recruiter judgment is another. A high ATS score gets you read, not interviewed. If you are clearing ATS but not getting calls, the issue is likely content quality, role fit, or volume. Have someone in the field review your bullets.
Tips
Aim for 90+ on parseability and 80%+ on JD keywords before submitting.
Single-column layouts always beat multi-column for ATS — visual appeal matters less than getting parsed.
PDFs render consistently across viewers; Word files preserve text more reliably for older parsers. PDF is usually safer in 2026.
A 90 ATS score gets you read by a recruiter; recruiter judgment is the next gate. ATS is necessary, not sufficient.
Test changes one at a time — running the checker after each edit shows which change helped.
