Optimize your resume for the ATS
A free independent diagnostic for extracted text: your diagnostic score, the keywords you're missing for the job, and the precise fixes. Paste, optimize, rescan — your resume never leaves your browser.
Quick answer: To optimize a resume for the ATS, make it parse cleanly (single column, standard headings, text-based file) and match the job description's keywords for skills you genuinely have. This tool scores both for free and shows the exact gaps to fix.

What ATS optimization actually fixes
Application workflows vary by employer. Read the actual vacancy and inspect your extracted text and submitted fields. Historical employer surveys do not establish a rejection rate for this role, country or file format; our score is an independent editing diagnostic.
The ATS optimization checklist
- Match the job's keywords — mirror the exact skills and titles from the job description (for things you genuinely have). Include only terms supported by your experience.
- Single-column layout — simple text flow is easier to inspect; complex layouts can produce extraction-order errors.
- Standard section headings — Experience, Education, Skills. Clear labels make the section easier to identify and review.
- Text-based file — selectable text is a useful first check; also inspect extraction order and application fields.
- Contact details in the body — not in a header, footer or text box, which are frequently dropped.
- Real dates & plain bullets — no tables, icons, or graphical skill bars, which add nothing the parser can use.
The scanner checks extracted text; it cannot inspect every visual layout property or reproduce an employer's parser. Read the scoring methodology to see what the diagnostic covers. Add a job description to compare its terms with your resume, then include only gaps that accurately reflect your experience.
Optimize, rescan, repeat — free
Optimization is iterative. Apply the fixes, paste your updated resume, and scan again as many times as you want — it's free and unlimited, no signup. The optional $9 report gives you every issue with line locations, the complete missing-keyword list, and bullet rewrite blueprints — the full optimization in one pass, for a one-time price rather than a subscription.
Frequently asked questions
What does ATS optimization mean?
ATS optimization means formatting and wording your resume so an applicant tracking system can parse it cleanly and match it to the job. In practice that's two things: a readable structure to inspect (single column, standard headings, real dates, no tables or text boxes), and the right keywords — the skills and titles from the specific job description, for things you genuinely have. Review both while preserving truthful experience; neither establishes a selection guarantee.
How do I optimize my resume for the ATS for free?
Paste your resume above (and the job description) and the free scan shows your parse score, a category breakdown, your top issues, and a preview of the keywords you're missing — no signup, nothing uploaded. Fix what it flags, paste the updated version, and rescan as many times as you like. The full optimization report (every issue with locations, all missing keywords, and original-preserving bullet guidance) is an optional one-time $9.
What are the most important ATS optimization factors?
Compare actual required qualifications and terminology with your experience. No independent checker can establish the strongest ranking factor for every employer. After that: a single-column layout, standard section headings (Experience, Education, Skills), a text-based file the parser can read, real date formats, and contact details in the body rather than a header or text box. Decorative templates with columns, tables and icons are the most common things that quietly break optimization.
Is keyword stuffing good for ATS optimization?
No. Unsupported keyword stuffing can misrepresent experience, and a wall of keywords reads as spam to the human who makes the decision. Optimize by including the job's important terms naturally — in real achievement bullets and a skills section — for skills you actually have. The goal is a resume that's both findable by the software and convincing to the person.
Does the optimizer upload my resume anywhere?
No. The entire analysis runs in your browser — your resume text is never sent to a server, and there's no account or email. You can verify it in your browser's network tab. Optimization without handing your personal details to a tool you've never used.
