The file you upload is the first thing the ATS touches. Here is how PDF and DOCX actually compare in real parsing tests — and how to export either one safely.
Last updated August 11, 2026
Quick Answer
Both PDF and DOCX work when exported correctly. Plain-text DOCX has the lowest parsing failure rate (~4%), while clean single-column PDFs fail ~18% of the time when complexly styled — and table- or multi-column-based files fail 31%+. The safest choice: export a real-text PDF or DOCX from Word or Google Docs with a single-column layout. Avoid design-tool PDFs, scans, and image-based exports entirely.
Real parsing tests give a clear ranking. EDLIGO's 2025 analysis of 1,000 rejected resumes across Workday, Taleo, and Greenhouse measured failure rates by file type — and the gap between formats is dramatic.
| File type | Failure rate | Best for |
|---|---|---|
| Plain-text DOCX | ~4% | Maximum compatibility — the safest default |
| Clean single-column PDF | ~18% (when complexly styled) | Designs that need fixed layout |
| Table- or multi-column-based files | 31%+ | Avoid — highest risk format |
| Scanned or image-based PDFs | Effectively unreadable | Never use for applications |

The rule of thumb
If you are unsure, export DOCX from Word or Google Docs. If you need a PDF, use 'Save as PDF' from the same tools — never export from a design app or print-to-PDF from a scan.
PDF wins on presentation fidelity; DOCX wins on parsing compatibility. When both are offered, either is acceptable as long as the file is a real-text export.
The select-text test
Open your PDF and try to select the text with your mouse. If you can highlight and copy individual words, it is a real-text PDF. If the whole page highlights as one image, an ATS cannot read it either.
Parsers are only half the audience. The recruiter who opens your file after screening has preferences too — and they rarely match the parser's.
The golden rule across all upload types
Whatever the method — file upload, cloud link, or paste — verify the text the system will read: single column, standard headings, real text, contact info in the body.
| Situation | Best format | Why |
|---|---|---|
| Corporate portal upload | DOCX or PDF | Both parse well; match the portal's preference |
| Emailing a recruiter directly | Renders identically; can't be edited | |
| Government / legacy systems | DOCX | Lowest failure rate, most compatible |
| Design-forward roles (portfolio context) | Fixed layout matters; keep text real | |
| ATS-heavy volume applications | DOCX | ~4% failure rate is the safest baseline |
Which format for which situation
Yes, indirectly — file type drives parsing reliability. Plain-text DOCX fails ~4% of the time, clean PDFs ~18% when complexly styled, and table/multi-column files 31%+. Both formats work if the text is real and the layout is single-column.
