Short version
Follow the instructions in the job posting first. If they ask for Word, send Word; if they ask for PDF, send PDF. If nothing is specified, a PDF with real text is a safe choice for online application forms, because it looks the same on every device. Keep a Word copy as well, since recruiters and staffing agencies sometimes need to edit or reformat a resume.
When PDF is better
PDF preserves fonts, spacing and page breaks exactly. Nothing shifts when it opens on a phone, a Mac or an older PC. It is also harder to change by accident. Make sure it was exported from a word processor or builder and so contains selectable text, not a scan or a screenshot.
When Word is better
Some older application systems, agencies and recruiters prefer .docx because they can edit it, add their own cover details or reformat it to a house style. A .docx also opens in Google Docs and LibreOffice. Use common fonts and avoid text boxes and tables so that it looks the same in different programs.
Mistakes to avoid
These cause real problems in either format:
- Sending a scan or a photo of a printed resume (no text to read).
- Putting contact details in the page header or footer, where some systems skip them.
- Using an unusual font that is replaced on another computer and shifts your layout.
- A vague file name. Use something like “Alex_Morgan_Resume.pdf”; the builder names downloads this way for you.
- A password on the file, which many systems cannot open.
Frequently asked questions
Do ATS prefer Word?
Modern systems read both well. Problems come from layout choices (columns, text boxes, images) and from scanned files, not from the format itself.
Can I get both from one design?
Yes. The free resume builder downloads the same resume as a PDF and as a Word file with one click each.
