How to use the ATS resume checker

1

Upload your resume

Drag and drop your PDF or DOCX file, or click to browse. Everything is processed in your browser — nothing is uploaded.

2

Add a job description (optional)

Paste a job posting to unlock keyword matching and see exactly which terms your resume is missing.

3

Get your ATS score

Receive an instant 0–100 score with a category breakdown and a prioritized list of issues.

4

Fix and re-scan

Open the Resume Builder to fix issues with ATS-safe formatting, then re-check until your score is green.

How to make your resume ATS-friendly

Use a single column

Multi-column layouts get scrambled by many ATS parsers. One clean column reads top-to-bottom reliably.

Standard section names

Use 'Experience', 'Education', and 'Skills' — creative headings can stop an ATS from mapping your content.

Quantify your impact

Numbers, percentages and dollar amounts in your bullets rank far higher than vague descriptions.

Real text, not images

Export a text-based PDF. Scanned or image resumes are invisible to ATS keyword scanning.

Mirror the job's keywords

Tailor your skills and experience to each posting using the exact terms the job description uses.

Avoid tables & graphics

Tables, text boxes, icons and charts frequently break parsing. Keep it to plain text and bullets.

How the ATS checker works

This free ATS resume checker analyzes your resume the way an Applicant Tracking System does — extracting the text, detecting sections, and scoring readability and keyword relevance — so you can fix problems before recruiters ever see it.

Browser-side parsing

PDF text is extracted with pdfjs and DOCX with mammoth — both run locally in your browser, so your file never leaves your device.

Section detection

The engine scans for standard headings and contact patterns to confirm your resume has every section an ATS expects to find.

Weighted scoring

Each category is scored 0–1 and combined with transparent weights — experience and skills count most, just like a real ATS.

Actionable fixes

Every issue comes with the reason it matters and a concrete fix, ranked by how much it will move your score.

Frequently asked questions

Common questions about the free ATS resume checker.

An Applicant Tracking System (ATS) is software recruiters use to collect, parse, and rank resumes before a human ever reads them. It extracts your text, looks for standard sections and keywords, and scores how well you match the role. Resumes get filtered out when the ATS can't read them (scanned images, multi-column layouts, tables), can't find key sections, or doesn't see the right keywords. This checker simulates those checks so you can fix issues first.

Yes — it's completely free with no signup, no account, and no limits. Upload as many resumes as you like and re-scan as often as you want.

No. Your resume is parsed and scored entirely inside your browser using JavaScript. The file never leaves your device and is never sent to any server. When you close the tab, nothing remains.

Both work as long as they contain real, selectable text. A text-based PDF is the safest choice for most modern ATS platforms. Avoid scanned-image PDFs (photos of a printed resume) — neither this tool nor an ATS can read them. DOCX is also widely supported and parses reliably.

We extract your resume text and score it across weighted categories: contact information, section completeness, skills, work experience (with action verbs and quantified results), formatting and ATS compatibility, and overall readability. If you paste a job description, we also measure keyword match. Each category contributes to a transparent 0–100 score with a letter grade.

A resume can look great to a human but confuse an ATS. Common culprits are multi-column layouts, tables, graphics, non-standard section headings, missing dates, and a lack of quantified achievements. The recommendations list pinpoints exactly what's hurting your score and how to fix it.

Yes. When you paste the job description, the tool extracts the role's key terms and shows which ones your resume already covers and which are missing — so you can tailor your resume to each application, which is exactly how ATS rank candidates.

Each recommendation links to our free Resume Builder, which applies ATS-safe formatting, a single-column layout, and standard section headers automatically, then exports a clean text-based PDF that parses perfectly on Workday, Greenhouse, Lever, iCIMS, Taleo and more.
