ATS Resume Scanner — Frequently Asked Questions

What is an ATS resume scanner?

An ATS (Applicant Tracking System) resume scanner is a tool that analyzes your resume to determine how well it will be parsed and scored by automated hiring software. It checks for keyword matches, proper formatting, section structure, and overall compatibility with Applicant Tracking Systems used by employers. Over 75% of large companies use ATS software to filter resumes before human review, making ATS optimization essential for job seekers.

Our free ATS resume checker provides instant, detailed analysis to help you beat these automated systems.

What file formats does the ATS scanner accept?

Our ATS resume scanner accepts the following file formats:

• PDF (.pdf) — Most common format, works with most ATS systems
• DOCX (.docx) — Word documents, typically parse most reliably across different ATS platforms
• Plain Text (.txt) — Simple text format for quick testing

Maximum file size is 5MB. For the best results, we recommend using DOCX format when possible. Learn more in our PDF vs DOCX for ATS comparison guide.

What is a good ATS resume score?

Our ATS scanner scores resumes out of 100 points:

• 80-100: Excellent — Your resume is highly optimized for ATS systems
• 60-79: Good — Your resume has a good chance of passing, with room for improvement
• 40-59: Fair — Some improvements needed for better ATS compatibility
• 0-39: Poor — Significant optimization required to pass ATS screening

The score is based on keyword matching (40%), formatting (25%), structure (20%), and readability (15%). For detailed tips on improving your score, read our ATS-friendly resume guide.

How can I make my resume ATS-friendly?

Follow these proven strategies to optimize your resume for ATS systems:

1. Use standard section headers (Work Experience, Education, Skills)
2. Match keywords from the job description naturally throughout your resume
3. Avoid complex formatting like tables, columns, text boxes, and graphics
4. Use a simple single-column layout with standard fonts (Arial, Calibri)
5. Submit in DOCX format when possible
6. Include clear dates (MM/YYYY) for all positions
7. Use bullet points to highlight achievements
8. Include both acronyms and full terms (e.g., "Search Engine Optimization (SEO)")

Does ATS reject PDF resumes?

Most modern ATS systems (like Workday, Greenhouse, and Lever) can parse PDFs effectively. However, some older ATS platforms still struggle with PDF files. DOCX (Word) documents tend to parse more reliably across different ATS platforms.

Our recommendation: unless the employer specifically requests a PDF, submit your resume as a DOCX file. If you must submit a PDF, ensure it's created from Word (not scanned) and is text-searchable. Learn more in our detailed PDF vs DOCX comparison.

What does the ATS score breakdown include?

Our ATS score is broken down into four specific categories:

• Keyword Match Analysis (40 points) — How well your resume matches the keywords and phrases from the job description
• Format Compatibility (25 points) — How well your resume formatting works with ATS parsers, checking for issues like special characters, tables, and complex layouts
• Section Structure (20 points) — Whether your resume includes all essential sections that ATS systems look for, like contact information, work history, education, and skills
• Readability Assessment (15 points) — Overall readability, resume length, bullet point usage, and date formatting for both ATS and human reviewers

Can I use the ATS resume checker on mobile?

Yes, our ATS resume scanner is fully responsive and works on all devices including smartphones, tablets, and desktops. The interface automatically adapts to your screen size for a seamless experience. You can upload resumes and paste job descriptions from any device.

How many times can I scan my resume?

There are absolutely no limits. You can scan your resume as many times as you want, against as many different job descriptions as you like, completely free. This allows you to optimize your resume for each specific job application. We encourage job seekers to test multiple versions of their resume against different job descriptions to maximize their chances of passing ATS screening.
