Resume File Format: PDF or Word?

"Never send a PDF, the ATS can't read it" is the most repeated piece of resume advice that is no longer true. It was true around 2010. Every mainstream applicant tracking system has parsed PDFs for years.

What each format costs you

A PDF renders identically everywhere. Your margins, fonts and spacing survive, and what the recruiter sees is what you built. The risk is that a PDF exported as an image — from a scanner, or from certain design tools — contains no text at all, and a parser reading it finds nothing. That failure is total and silent.

A .docx parses reliably but renders unpredictably. Open it on a machine without your font and the layout reflows; a two-page resume becomes three, and your carefully placed section break lands mid-bullet. It is also editable, which means a recruiter can alter it before it reaches the hiring manager — usually to strip your contact details, which agencies do routinely.

The test that settles it in ten seconds

Open your PDF, select all, copy, paste into a plain text editor. If your text appears, the file has a real text layer and any parser can read it. If you get nothing, it is an image and it will fail — that is the actual risk people are warning about, stated properly.

When Word still wins

• The application explicitly asks for .docx. Follow the instruction; it is sometimes a compliance test.
• You are going through a recruitment agency that reformats candidates onto their own template. They will ask anyway.
• The upload form rejects PDFs, which a few older systems still do.

What actually matters more than the format

Whether the document has a single-column reading order, standard section headings, consistent date formats and no text trapped in images or headers. Get those right and both formats parse. Get them wrong and neither does.

Name the file properly too: "Firstname-Lastname-Role.pdf". "resume-final-v3-USE-THIS.pdf" lands in a folder of two hundred files and tells nobody anything.
