PDF vs. Word: Which File Format Do ATS Scanners Prefer?

The File Format Debate

When it comes time to submit your resume, you face a seemingly simple decision that can have significant consequences: should you submit a PDF or a Word document? This question has been debated in career circles for years, and the answer is more nuanced than most people think. The right choice depends on the ATS being used, the company's preferences, and how your resume was created.

The Case for PDF

PDF, or Portable Document Format, is designed to preserve your document's layout exactly as you created it, regardless of what device or operating system opens it. This is a major advantage for visual consistency — your carefully chosen fonts, spacing, and alignment will look identical on every screen and printer.

Modern ATS platforms parse text-based PDFs with high accuracy. Systems like Greenhouse, Lever, Workday, and modern versions of Taleo can extract text, identify sections, and index keywords from well-structured PDFs without issues. The key qualifier is "text-based" — the PDF must contain actual selectable text, not a scanned image of text.

PDFs also have the advantage of being tamper-proof. Once exported, the content cannot be accidentally modified, which ensures the recruiter sees exactly what you intended.

The Case for Word (DOCX)

DOCX files are the native format for Microsoft Word and are inherently text-based, making them easy for any ATS to parse. Some older ATS platforms that were built before PDFs became standard were designed primarily for DOCX processing. For these legacy systems, DOCX may provide slightly more reliable parsing.

DOCX files are also editable, which can be an advantage or disadvantage. Some recruiters prefer DOCX because they can reformat your resume or add their agency's branding before forwarding it to clients. However, this editability also means your formatting might be altered unintentionally.

When PDF Is Better

• When the job application does not specify a format preference
• When your resume uses custom fonts or precise formatting you want to preserve
• When applying through modern ATS platforms (Greenhouse, Lever, Workday)
• When emailing your resume directly to a hiring manager
• When you want to ensure your document cannot be accidentally altered

When DOCX Is Better

• When the job posting explicitly requests a Word document
• When applying through older ATS platforms known to struggle with PDFs
• When working with recruitment agencies that need to edit or rebrand your resume
• When the application portal only accepts DOCX files

Formats to Never Use

Some file formats should never be used for resume submissions:

• .jpg, .png, or other image formats: ATS cannot extract any text from images. Your entire resume is invisible to the system.
• .pages: Apple Pages format is not supported by most ATS platforms and may not even open on Windows systems.
• .odt: Open Document Format has inconsistent ATS support and may lose formatting.
• Google Docs links: Always download and upload a file rather than sharing a link. ATS cannot crawl external links.

How to Create an ATS-Safe PDF

Not all PDFs are created equal. A PDF exported from a word processor like Google Docs, Microsoft Word, or our free resume builder contains embedded text that ATS can read. However, a PDF created by scanning a physical document, exporting from a design tool like Photoshop, or "printing to PDF" from certain applications may be image-based — meaning ATS sees a blank page.

To verify your PDF is text-based, open it and try to select text with your cursor. If you can highlight individual words, it is text-based and ATS-safe. If clicking selects the entire page as one block or does not allow selection at all, it is image-based and needs to be recreated.

Our Recommendation

For the vast majority of modern job applications, PDF is the best choice. It preserves your formatting, is universally readable, and is parsed accurately by all major ATS platforms in use today. Only switch to DOCX if the job posting explicitly requests it.

Our free resume builder exports clean, text-based PDFs that are optimized for both ATS parsing and visual presentation. Every resume you create is guaranteed to be parseable by any ATS on the market.
