PDF vs DOCX for ATS: Which Resume Format Passes Screening Better?
One of the most debated questions among job seekers: should you submit your resume as a PDF or a DOCX file?
The answer isn't as simple as it used to be. Modern ATS systems have evolved, but old ATS limitations still exist. In this guide, we'll break down exactly how different file formats perform across major ATS platforms and give you a clear recommendation.
The Short Answer
DOCX is the safest choice for maximum ATS compatibility. While most modern ATS systems handle PDFs well, DOCX files parse more reliably across the widest range of platforms. If the employer doesn't specify a format, upload a DOCX.
Test both formats with our free ATS resume scanner to see how each one performs.
ATS Compatibility by File Format
| File Format | ATS Compatibility | Best For | Risks |
|---|---|---|---|
| DOCX (.docx) | Excellent — Virtually 100% | Maximum compatibility | Minor formatting shifts between Word versions |
| PDF (.pdf) | Good — 85-95% | Preserving visual design | Some older ATS struggle; scanned PDFs fail completely |
| Plain Text (.txt) | Perfect — 100% | ATS-only submission | No visual formatting; unprofessional for human readers |
| DOC (.doc) | Good — 80-90% | Legacy system compatibility | Outdated format; can have compatibility issues |
How Different ATS Platforms Handle PDF vs DOCX
ATS compatibility varies significantly by platform. Here's how the major systems handle each format:
Workday
DOCX: Excellent parsing. Correctly extracts all text, section headers, bullet points.
PDF: Good parsing. May have minor issues with complex layouts.
Greenhouse
DOCX: Excellent. One of the most reliable formats.
PDF: Good. Greenhouse handles most PDFs well.
Lever
DOCX: Excellent.
PDF: Good to excellent.
SAP SuccessFactors
DOCX: Excellent.
PDF: Variable. Older SuccessFactors instances may struggle.
Taleo (Oracle)
DOCX: Excellent.
PDF: Variable — Taleo has historically had more PDF parsing issues than other platforms.
iCIMS
DOCX: Excellent.
PDF: Good to excellent.
When to Use PDF
Despite DOCX being generally safer, PDF is sometimes the better choice:
- When the employer specifically requests PDF — Always follow instructions
- When you need to preserve exact formatting — PDF ensures your resume looks identical on any device
- When applying to companies known to use modern ATS — Tech companies using Greenhouse, Lever, or modern Workday handle PDFs well
- When submitting via email directly to a recruiter — PDF looks more professional
When to Use DOCX
- When no format is specified — Default to DOCX for safety
- When applying to large corporations — They often use older ATS like Taleo
- When applying to government or legacy systems — These often have the most parsing issues
- When you're unsure about the ATS used — DOCX is the safest bet
PDF Pitfalls to Avoid
If you must submit a PDF, avoid these common problems:
- Scanned PDFs: A scanned document is an image, not text. ATS cannot read it. Always create PDFs from Word or Google Docs.
- Password-protected PDFs: Many ATS cannot open protected files.
- PDFs with embedded fonts: Unusual fonts may not render or parse correctly.
- PDFs with layers/transparency: Complex PDF features can confuse parsers.
How to Create an ATS-Friendly DOCX
- Use Microsoft Word or Google Docs (save/export as .docx)
- Single-column layout with standard fonts (Arial, Calibri)
- No tables, text boxes, or floating elements
- Standard section headers
- Save as "Word Document (*.docx)"
- Name your file professionally: "FirstName_LastName_Resume.docx"
How to Create an ATS-Friendly PDF
- Create your resume in Word or Google Docs first
- Ensure all text is selectable (not an image)
- Export/Save As PDF
- Open the PDF and try to select text — if you can, ATS can read it
