PDF vs DOCX: Which Resume File Format Do ATS Prefer?
The definitive answer to a debate that costs job seekers interviews — and when each format is the right call.
It's one of the most common job-search questions: should you send a PDF or a Word document? Here's the honest answer.
The short version
- DOCX is the most universally parse-able format. Older enterprise ATS (Taleo, iCIMS, some Workday flows) read it most reliably.
- PDF preserves your formatting exactly and is parsed well by most modern systems — as long as it contains real, selectable text.
When to use each
- Uploading to a company ATS / job portal: DOCX is the safest default unless they specify PDF.
- Emailing a recruiter directly or applying somewhere modern: PDF keeps your layout intact.
- When in doubt: have both ready and follow the posting's instructions.
The mistake that breaks both
A PDF exported as an image (scanned, or "print to PDF" from some tools) has no readable text. Test it: open the file and try to select and copy a line. If you can't, neither can the ATS.
The format matters less than the content and structure — but when a posting doesn't specify, DOCX is the lower-risk choice.
