ATS Resume Optimiser
Paste your resume and a job description — get a keyword gap analysis and specific edits to help your resume pass the ATS scan.
Most large employers now run every resume through an Applicant Tracking System (ATS) before a human ever sees it. The ATS parses your resume into structured data and scores how well it matches the job description — and a resume that is missing the right keywords, or formatted in a way the parser can't read, often gets filtered out automatically. This free tool compares your resume against a specific job posting, shows you the keyword gaps, flags formatting that can trip up the parser, and rewrites key bullet points so they match the role without sounding stuffed. Use it once per job you apply to — tailoring beats a single generic resume every time.

- 2Paste the complete job description you're targeting into the second box, including the requirements and responsibilities.
- 3Optionally add the exact job title so the analysis can weight the most important terms.
- 4Click Generate to get a match score, a prioritised list of missing keywords, formatting flags, and before/after bullet rewrites.
- 5Apply the critical changes, then run your updated resume through the tool again for a fresh score. Re-tailor for each new job.
What to Include
- Standard section headings (Summary, Experience, Skills, Education) the parser recognises
- Hard skills and tools from the job description, spelled exactly as they appear
- Both the acronym and the full term for key qualifications (e.g. "SEO (Search Engine Optimisation)")
- A dedicated skills section — don't bury keywords only inside paragraphs
- Measurable results in your bullets (numbers, %, $, time saved)
- A simple, single-column layout — no text boxes, tables, or images for critical content
Frequently Asked Questions
What is an ATS and why does it reject resumes?▾
An Applicant Tracking System is software employers use to collect, parse, and rank job applications. It reads your resume into fields, then scores it against the job's required skills and keywords. Resumes get filtered out when the parser can't read the layout (tables, columns, headers/footers, images) or when the content is missing the terms the employer flagged as important. It's rarely a single "reject" button — more often your resume simply ranks too low to be surfaced to a recruiter.
Is keyword matching just stuffing my resume with words?▾
No — and keyword stuffing usually backfires, because a human eventually reads the shortlisted resumes. The goal is genuine, relevant alignment: if the job asks for "stakeholder management" and you've done it, use that exact phrase rather than a synonym. This tool only surfaces keywords tied to skills you can legitimately claim and shows you where to place them naturally.
What resume format is most ATS-friendly?▾
A clean, single-column layout with standard section headings, a normal font, standard bullet points, and dates in a consistent format. Avoid tables, text boxes, multi-column designs, images, and putting contact details in the header/footer — many parsers skip those regions. Save as a .docx or a text-based PDF (not a scanned image).
Should I tailor my resume for every job?▾
Yes. A resume tailored to a specific posting almost always scores higher than one generic version sent everywhere, because ATS ranking is relative to that job's keywords. Tailoring doesn't mean rewriting from scratch — usually it's adjusting your summary, reordering skills, and reworking a few bullets to mirror the language of the posting.
Does this tool guarantee I'll pass the ATS?▾
No tool can guarantee that — every employer configures their ATS differently, and the final decision is human. What this does is remove the avoidable reasons a strong candidate gets filtered out: missing keywords, unreadable formatting, and weak, unquantified bullets. It's an optimisation aid, not a magic pass.
