DOCX vs PDF for ATS: Which Resume Format Actually Gets Read

The format question comes up in almost every resume conversation. PDF looks professional and consistent — it displays the same way on every screen, every device. DOCX looks editable. Most candidates choose PDF for exactly that reason.

Here's the problem: the first thing that reads your resume usually isn't a human. It's an applicant tracking system. And how well it reads your resume depends significantly on the file format.

Why Format Matters for ATS Parsing

When you upload a resume to a company's careers portal, the ATS runs it through a parsing engine before any human sees it. The parser's job is to extract your name, contact details, work history, education, and skills — and load them into a structured candidate database.

The parser doesn't care how your resume looks. It cares about how cleanly it can extract text from your file.

The two formats solve different problems. PDF was designed as a presentation format — it preserves visual layout by describing where every character appears on a page. DOCX was designed as a document format — it stores text in structured XML, with explicit tags for headings, paragraphs, and styles. ATS parsers are built to consume structured text. That gives DOCX a structural advantage.

The Three Types of PDF Resumes

Not all PDFs behave the same way in an ATS. There's an important distinction.

Text-based PDF — created by exporting from Word, Google Docs, or similar tools. The text is embedded in the file and can be extracted by a parser. Most modern ATS systems can handle these reasonably well, though complex layouts can still cause problems.

Design-tool PDF — created in Canva, Adobe Illustrator, Figma, or InDesign. Even though it looks like a document, the text is often stored in vector paths, not as extractable text characters. Many ATS parsers can't read these at all, or extract garbled output.

Scanned PDF — a photograph or scan of a printed resume. The ATS sees an image. It cannot extract any text. This results in a blank candidate profile, often with no error message to tell you something went wrong.

If you're submitting a PDF, it must be a text-based PDF from a standard word processor — not a design tool, not a scan.

Where DOCX Performs Better

The XML structure of a DOCX file exposes information that helps an ATS parser: heading levels, paragraph styles, document structure. When you mark a section as Heading 2 in Word, the DOCX file explicitly tags that element. The parser can use those tags to identify section boundaries and map content to the right fields — Work Experience, Education, Skills.

A PDF, even a clean text-based one, contains positional information ("this text appears at coordinates X, Y") rather than structural information ("this text is a section heading"). The parser has to infer structure from layout, which introduces more opportunity for error.

The practical result: the same resume content, exported as DOCX versus PDF, will often produce a more accurate candidate profile as a DOCX. Dates are less likely to be scrambled. Job titles are less likely to split. Skills are more likely to be extracted correctly.

The ATS-by-ATS Reality

Different systems handle formats differently:

Workday accepts both DOCX and text-based PDF. DOCX is the safer choice, particularly for complex documents, because Workday uses paragraph styles as parsing signals. Text-based PDFs work but provide fewer structural hints.

Taleo (used by many large enterprises) has historically had more trouble with PDFs than DOCX. Its parser handles clean single-column DOCX most reliably. Taleo also has documented issues with special-character bullets (•, ◆, →) — plain hyphens are safer.

Greenhouse handles text-based PDFs well and is generally the most parser-tolerant of the major systems. DOCX still works reliably; the format gap is smaller here.

SAP SuccessFactors recommends DOCX through its own guidance and has documented parsing failures with design-tool and scanned PDFs.

iCIMS parses both formats but, like most systems, produces more accurate results from DOCX on complex layouts.

The through-line: no major ATS system reliably prefers PDF over DOCX. Several explicitly prefer DOCX.

When PDF Is Still the Right Choice

Format isn't a binary rule. Context matters.

When emailing a recruiter directly — a PDF is the right call. It will display identically on their screen, and they're reading it as a human, not parsing it through software. A DOCX file emailed directly can display differently depending on their version of Word.

When a recruiter or job posting explicitly requests PDF — follow the instruction. Some recruiters prefer PDF because it prevents candidates from editing the document after submission.

When applying to a company with a modern, tolerant ATS — a clean, single-column, text-based PDF will usually work fine.

The default, when you're uploading to a company careers portal with no format instruction: use DOCX.

What Format Can't Fix

Format is one variable. It doesn't compensate for the other factors that cause ATS failures.

A two-column layout will break parsing in DOCX just as it does in PDF. Tables used for layout cause problems in both formats. Contact information placed in a Word header section may not be extracted regardless of file type.

Format matters, but structure matters more. A single-column DOCX with standard section headings, no tables, and contact details in the document body will outperform a two-column DOCX every time. For a complete breakdown of structure requirements, see the ATS-friendly resume format guide.

The Simple Rule

Submit DOCX when you're uploading to a company careers portal and no format is specified. Submit PDF when you're emailing a human or when the posting explicitly asks for it.

PassATS accepts both PDF and DOCX resumes. It extracts your resume text, matches it against the job description keywords, and rewrites it in ATS-safe format — so what gets submitted to the parser is optimised for the system on the other end.
