Check your resume against a job
Works with any role and any country. Everything happens in this browser tab: we never see your resume or the job description.
What the scan looks at
- Keywords, weighted the way the posting weighs them
- Skills under "requirements" count three times as much as nice-to-haves. We recognise common alternatives — k8s for Kubernetes, CI/CD for continuous integration — and flag terms that only appear in your skills list but never in your experience.
- What an ATS will actually extract
- For PDFs we measure how many lines sit side by side in columns. For Word files we count tables and images. We check for contact details in the body, standard headings, readable dates and broken characters.
- Whether your bullets show results
- We count how many bullets include a number and how many open with a strong verb, and point out openers like "responsible for" that hide what you did.
- The job title and the basics
- Whether your resume uses the title from the posting, how many years of experience it asks for, and whether you have the sections recruiters expect.
Every weight is published on the methodology page. If a check is a strong signal rather than a measurement, the report says so.
Your resume has your phone number on it. It shouldn't need to leave your laptop.
Most resume checkers upload your file to their servers, and many send it to an AI service. We built ATS Scanner Pro to do the whole analysis in your browser instead. If you open your browser's developer tools and watch the network tab while you scan, you'll see that nothing is sent.
That also means there's no cost to us per scan, which is why we don't need to limit how many you run. Scan every application you send.
Guides that answer the next question
All guides- How an ATS reads your resumeWhat applicant tracking systems really do with your resume: parsing, search, knockout questions and ranking — and which myths to stop worrying about.
- Finding resume keywordsA step-by-step method for pulling the keywords that matter out of any job posting, deciding which to use, and placing them so they read naturally.
- ATS-friendly resume formatThe layout, headings, fonts, dates and file settings that parse cleanly in applicant tracking systems — with what to avoid and why.
- ATS scores explainedWhy every resume checker gives a different ATS score, what the number can and can't tell you, and why chasing 100% usually makes a resume worse.
- PDF or DOCX?When to send your resume as a PDF and when as a Word file, how to export a PDF that parses cleanly, and the file problems that break applications.
- Quantifying resume bulletsPractical ways to find and phrase numbers for resume bullets — scale, speed, money, quality — with examples for roles that don't track metrics.

Questions
Is ATS Scanner Pro really free?
Yes. There are no scan limits, no sign-up and no paid tier for the web scanner. The site is supported by a small number of clearly labelled ads on some pages.
Is my resume uploaded anywhere?
No. Your file is opened and analysed by code running in your own browser tab. It isn't sent to our servers or to any AI service, and nothing is kept after you close the page except, if your browser allows it, your last score for each job description so we can show progress.
How accurate is the score?
It's our own estimate, built from the same signals most applicant tracking systems rely on: the posting's important terms, clean parsing, standard sections and clear results. Employers' systems are configured differently and none publish their formulas, so treat the score as a guide and the list of missing terms as the useful part. The full formula is on our methodology page.
Will this guarantee me an interview?
No tool can. A better-matched, cleanly formatted resume is more likely to appear in a recruiter's search and to be read, but hiring decisions depend on your experience, the other applicants and the team.
Should I add every missing keyword?
Only the ones that are true. Recruiters and interviewers ask about what's on the page, and adding skills you don't have tends to come out quickly. Use the list to spot things you have done but didn't name.
Which file types work?
PDF, DOCX and TXT, up to 8 MB. You can also paste plain text. Scanned PDFs and old .doc files can't be read — and many applicant tracking systems struggle with them too.
Does it work for jobs outside tech?
Yes. The keyword list covers engineering, data, product, design, marketing, sales, finance, HR, operations, healthcare and education, and the scanner also picks up tool names and repeated phrases it hasn't seen before.
