Introducing ATS Checker: Free, Private, Effortless Resume Analysis

Why does it matter?

Most large companies use ATS — Applicant Tracking Systems — to filter resumes before a human ever sees them. Even a perfect background can be missed if your resume isn’t machine-readable.

Many resumes fail ATS parsing because of layout issues, non-standard fonts, multi-column formats, or scanned PDFs. If your document isn’t an ATS compatible resume PDF, it may never reach a real person.

How does ATS Checker work?

• Upload your resume as a PDF (other formats are not supported).
• Instantly get a professional analysis: structure, readability, and clear recommendations.
• All processing happens locally in your browser — your file never leaves your device.
• Results appear in seconds. No waiting, no uploads, no accounts.

Check → Fix → Re-check.
With A4CV, you can check your resume for ATS issues, edit instantly in the Resume Builder, and re-check as many times as you need — all without exporting, uploading, or creating an account.
