ATS Resume Checker
See exactly what an ATS parser extracts from your resume — not just a score.
Also known as: ATS resume scanner, ATS resume scan, Resume parser checker
How it works
- 1Upload your resume as a .pdf or .docx file.
- 2Read the score strip for an at-a-glance summary, then compare the raw extraction pane against the findings pane.
- 3Fix anything marked critical first — these are documented parsing failures, not style opinions.
- 4Paste a job description into the keyword-match panel to see which of its exact phrases your resume already covers.
- 5Add any genuinely relevant missing keywords, then re-upload the updated file to confirm the fixes landed.
Why use ATS Resume Checker
Shows the actual extracted text, not just a score
The raw-extraction pane is built from the same text your resume would yield to a real parser — you see the jumbling or gaps directly instead of trusting a number.
Every finding is a documented, checkable fact
Header/footer detection, table detection, and text-box detection all come from reading the file's actual structure — not a heuristic guess dressed up as certainty.
No email gate, no paywalled depth
The full findings list and the full keyword-match breakdown are visible on the first scan — nothing is held back behind a signup form.
Honest keyword matching
An exact, literal gap list of missing job-description phrases — the kind of matching real platforms like Workday and Taleo actually use — instead of an unverifiable AI-generated score.
Works for both PDF and DOCX
PDF gets position-aware column detection; DOCX gets true header/footer and text-box detection, since each format's parsing risks are genuinely different.
Nothing uploaded
Every parse, check, and keyword comparison happens locally in your browser — your resume and any job description you paste never leave your device.
Who uses ATS Resume Checker
Sanity-checking a resume before a big application round
Catch a header-only email address or a stray text box before it silently costs you a callback.
Deciding between a PDF or DOCX export
See exactly how your specific layout parses in each format rather than following generic format advice.
Tailoring a resume to one specific job posting
Paste the posting in and see precisely which of its keywords are missing before you submit.
Auditing a template you didn't design yourself
Templates downloaded from design sites are a common source of hidden text boxes and multi-column layouts — this surfaces them.
Career coaches and resume writers reviewing client documents
A fast, concrete second opinion grounded in real parsing behavior rather than a subjective style read.
About ATS Resume Checker
An ATS doesn't see your resume the way you do. Most systems run a text extractor over your file that reads content in a fixed order — usually left-to-right, top-to-bottom through the document's underlying structure — with no understanding of columns, visual grouping, or design intent. A two-column layout that looks clean on screen can have its job titles and dates interleaved with an unrelated skills sidebar once that structure is flattened into plain text. This tool renders that exact flattened text so you can see it happen, rather than asking you to trust a score.
The checks here are all grounded in documented, specific parsing behavior rather than generic "best practice" advice. DOCX files have a genuinely separate header/footer layer in their file format — many parsers only read the document body, so contact info placed in a header can be invisible to the exact system deciding whether a recruiter ever sees your resume. Text boxes sit outside the normal document flow and are often dropped entirely, not just misread. Tables can scramble reading order, particularly on platforms like Workday. None of this is guesswork — it's read directly from the file's actual structure.
The keyword-match panel is deliberately built without an AI API call: it tokenizes your resume and the pasted job description, extracts the job description's most distinctive single words and two-word phrases (skipping comma-separated lists so "Kubernetes, Docker" never becomes a fake phrase "Kubernetes Docker"), and checks for their literal, word-boundary presence in your resume. That's paired with an overall overlap score based on log-weighted term frequency between the two documents — described honestly as a general similarity signal, not a certified match percentage, since a meaningful two-document comparison can't use true corpus-wide TF-IDF weighting.
One honest caveat this tool won't hide: no free checker can guarantee how a specific employer's specific ATS configuration behaves, since implementations genuinely vary — Workday, Taleo, iCIMS, Greenhouse, Lever, and SuccessFactors all parse and match differently. Every finding here is a real, checkable fact about your document, not a promise about any particular outcome.
ATS Resume Checker vs. other options
How Open Tools Library compares to desktop software and other online tools.
| Feature | Open Tools Library | Desktop software | Other online tools |
|---|---|---|---|
| Price | Free, unlimited scans | N/A — not a desktop category | Often one free scan, then a paid plan |
| Email required to see results | Never | N/A | Frequently required |
| Shows the actual raw extracted text | Yes, side by side with findings | N/A | Rarely shown — usually just a score |
| Keyword matching approach | Literal exact-phrase gap list, disclosed honestly | N/A | Often an opaque "AI match score" |
| Account required | Never | N/A | Often required |
Pro tips
- Fix critical findings before warnings — they map to documented cases where content can become invisible or scrambled, not just suboptimal.
- If you see a multi-column warning, check the raw-extraction pane for the exact jumbled line it's pointing at — that's literally what a parser would read.
- A missing keyword only matters if it's genuinely true of your background — don't add a skill you don't have just to pass a scan.
- If you don't know which ATS a specific employer uses, DOCX is the more conservative format choice; most modern systems handle PDF fine.
- Re-run the check after every real edit — the raw-extraction pane updates from the exact new file, so you can confirm a fix actually worked.

Privacy & security
A resume is one of the most personal documents you own — checking it shouldn't require handing it, or an email address, to a server.
Every parse, formatting check, and keyword comparison runs locally in your browser.
Your resume file and any job description you paste are never uploaded anywhere.
No account, email, or login required to see the full results.
Nothing is stored or logged after you close the tab — reload the page and you start fresh.
Frequently asked questions
Is this tool free to use?
Yes, completely free, with no limit on how many resumes or job descriptions you check and no email required to see full results.
Does this upload my resume anywhere?
No — parsing, every check, and the keyword match all run locally in your browser. Nothing is sent to a server.
Can this guarantee my resume will pass a specific company's ATS?
No honest tool can promise that — ATS platforms like Workday, Taleo, iCIMS, Greenhouse, Lever, and SuccessFactors each parse and match differently, and 97.8% of Fortune 500 companies use some form of ATS across many different vendors. What this tool can do is show you real, documented parsing risks in your actual file.
Why show the raw extracted text instead of just a pass/fail score?
A single score hides exactly what you'd need to fix. Seeing the literal text a parser would read makes formatting problems concrete and checkable instead of abstract.
How is the keyword match calculated without an AI model?
It tokenizes both documents, extracts the job description's most distinctive words and two-word phrases (respecting sentence and list boundaries so unrelated comma-listed items never get merged into a fake phrase), and checks each one for literal presence in your resume — the same kind of exact matching platforms like Workday and Taleo actually use.
Troubleshooting
My resume looks fine — why is it flagged for multiple columns?
The detector looks for large horizontal gaps within the same visual line of text, which usually means two columns (or a table row) sharing that line. Check the evidence line shown in that finding — if it's a false positive from unusual spacing rather than a real column layout, you can treat that specific finding as low-risk.
Why does the raw-extraction pane look garbled even though my resume looks normal?
That's the point of showing it — the garbling is what a real parser sees. If a job title and company name are jammed together with no space, that's genuinely how a naive text extractor would read that line.
The keyword-match score seems low even though I cover most of the job description's topics.
The overlap score measures term-frequency overlap, not topical understanding — a resume that phrases things differently than the posting can score lower even when it's a strong fit. Treat the exact missing-keywords list as the more actionable signal.
Why weren't any of my bullet points flagged, even though I used a fancy bullet icon?
Bullet-glyph checking only applies to PDF, where bullets are literal characters in the text stream. In DOCX, bullets are structured list metadata rather than a literal risky glyph, so they're handled differently and don't trigger this specific check.
I uploaded a scanned or photographed resume and got almost nothing back.
That's an accurate result, not a bug: a scanned or photographed PDF has no real text layer, just an image, and this tool doesn't silently pretend otherwise. It runs OCR so you can see a reference preview of what's on the page, but that preview is clearly labeled and never counted as real extracted text — because real ATS platforms essentially never OCR resumes either. If your file is a scan, the highest-impact fix is to replace it with an export from the original Word, Google Docs, or design file.
