What is an ATS and why should you care?
Understanding how Applicant Tracking Systems work is the first step to getting past them.
Without ATS optimization
- Resume gets auto-rejected before any human sees it
- Image-based PDFs are completely unreadable by ATS
- Missing keywords mean low ranking even if qualified
- Fancy formatting gets scrambled into gibberish
With Resumly ATS checker
- Real-time score updates as you type each section
- Text-based PDF output that every ATS can parse
- Specific suggestions for what to add or change
- Clean, standard formatting ATS systems expect
An Applicant Tracking System (ATS) is software used by virtually all mid-to-large companies to filter resumes before a recruiter reviews them. It scans for specific keywords, checks formatting compatibility, and ranks candidates. If your resume does not pass the ATS filter, no human will ever see it — regardless of your qualifications. Our built-in ATS checker analyzes your resume against the same criteria these systems use, so you know you are ready before you hit "Apply."

Understanding your ATS score
Here is what each score range means and what to do about it.
Your resume is fully optimized for ATS. You are ready to apply with confidence.

Your resume may be filtered out by some ATS systems. Follow the suggestions to improve.
Your resume is likely to be rejected by ATS. Significant changes are needed before applying.
6 ATS mistakes that get resumes rejected
Avoid these common formatting and content errors that cause ATS systems to reject otherwise strong resumes.
Using tables, columns, or text boxes
Fix: Use a single-column layout with clear section breaks. ATS parsers struggle with multi-column layouts and may scramble your content.
Saving as image-based PDF
Fix: Use a builder like Resumly that generates text-based PDFs. If ATS cannot select/copy text from your PDF, it cannot read your resume.
Fancy section headings
Fix: Use standard headings: "Work Experience" (not "Where I've Been"), "Education" (not "Academic Journey"), "Skills" (not "What I Bring").
Missing keywords from the job description
Fix: Read the job posting carefully. Mirror the exact terms they use — if they say "project management," use that phrase, not "managing projects."
Headers and footers for contact info
Fix: Many ATS systems cannot read content in headers/footers. Place your contact information in the main body of the resume.
Using abbreviations without spelling them out
Fix: Write "Search Engine Optimization (SEO)" first, then use "SEO" after. ATS may search for either form.
Why text-based PDFs are critical for ATS
Many resume builders use screenshot-to-PDF conversion, creating image files that look great but are completely unreadable by ATS. The text in your resume is literally a picture — no machine can extract words from it.
- • ATS sees a blank page
- • Cannot extract any text
- • Cannot match keywords
- • Auto-rejected every time
- • ATS reads every word
- • Full text extraction
- • Keywords matched accurately
- • Properly ranked and scored
Frequently Asked Questions
What is an ATS resume checker?
An ATS resume checker analyzes your resume against the same criteria that Applicant Tracking Systems use to filter candidates. It checks formatting, keywords, section structure, and completeness to predict whether your resume will pass automated screening.
Is the Resumly ATS checker free?
Yes, completely free. The ATS score is built into our resume builder and updates in real-time as you create your resume. There are no hidden fees, no premium tier required, and no upload limits.
How does the real-time ATS scoring work?
As you fill in each section of your resume (contact info, summary, experience, skills, education), our checker evaluates completeness, keyword density, formatting compliance, and overall structure. Your score updates instantly with each change.
What ATS score should I aim for?
We recommend aiming for 80% or higher before submitting your resume. A score of 90%+ means your resume is fully optimized. Scores below 70% indicate significant issues that could cause your resume to be filtered out.
Why do text-based PDFs matter for ATS?
ATS systems need to extract text from your resume file to analyze it. Image-based PDFs (created by screenshot-to-PDF tools) contain no extractable text — the ATS sees a blank page. Resumly generates text-based PDFs where every word is real, selectable text that ATS systems can read.
Can I check an existing resume I already have?
Our ATS checker is integrated into the resume builder rather than being a file upload tool. This means you get real-time feedback as you build, which is more actionable than a one-time scan. Simply start a new resume in our builder and enter your existing content to see your score.
Which ATS systems does this work with?
Our checker evaluates your resume against general ATS parsing standards used by all major systems including Workday, Greenhouse, Lever, iCIMS, Taleo, and BambooHR. The formatting and structure checks are universal across all ATS platforms.
Do I need to optimize my resume for every job application?
Yes, tailoring your resume for each job description significantly improves your ATS score and callback rate. Focus on matching the specific keywords and skills mentioned in the job posting. Our AI suggestions can help you identify the right keywords quickly.
