Resume File Format: PDF vs Word vs Others

The format matters more than you think

Your resume content can be perfect, but if the file format breaks, it doesn't matter.

The right format ensures:

• Your formatting stays intact (spacing, fonts, alignment)
• ATS systems can parse your content correctly
• Recruiters see what you intended (not a mangled layout)
• The file works across devices and platforms

Most of the time, that format is PDF.

Why PDF wins (most of the time)

PDF is the default choice because it preserves formatting.

When you export to PDF, what you see is what recruiters see. Your typography stays intact, your spacing remains consistent, your alignment doesn't shift. A resume that looks clean in your editor looks clean when printed or viewed on screen.

PDFs also work across platforms. They render the same on Windows, macOS, Linux, mobile devices. You don't have to worry about "does this recruiter have the right fonts installed?" or "will Word mess up my spacing?"

For ATS systems, modern parsers handle PDFs well. Most systems can extract text, dates, and structure from PDFs reliably. The parsing might not be perfect (no format is), but PDFs give parsers enough structure to work with.

When Word makes sense

Use Word (.docx) when:

• The job posting explicitly requests Word format
• The ATS system is known to struggle with PDFs (older systems, some niche platforms)
• You're applying to organizations that edit resumes before forwarding (rare, but happens)

Word has one advantage: it's easier for systems to extract and modify. But that's often not what you want — you want your resume to stay exactly as you designed it.

If you must use Word:

• Use standard fonts (Arial, Calibri, Times New Roman)
• Keep formatting simple (avoid complex tables, text boxes)
• Test that the document opens correctly in different Word versions
• Save as .docx (not .doc) for better compatibility

Other formats (and why to avoid them)

Plain text (.txt): Preserves nothing — no formatting, no structure, no visual hierarchy. Only use if explicitly requested. Your resume becomes a wall of text.

HTML: Some systems accept HTML resumes, but they rarely render as intended. The styling gets stripped or mangled, and you lose control over appearance.

Google Docs links: Don't share editable links. Export as PDF and send the PDF file.

Images (PNG, JPG): Some niche cases (portfolio sites, creative fields) use image resumes, but they break ATS parsing completely. Avoid unless you're in visual design and your portfolio is the primary proof.

ATS parsing: PDF vs Word

Modern ATS systems parse both PDFs and Word docs, but they parse differently.

PDFs preserve structure better. Headings, bullets, dates — if they're formatted correctly in the source, they stay formatted in the PDF. ATS parsers can use that structure to extract fields reliably.

Word docs are more flexible, which means parsers have to infer structure more. If your Word doc uses styles (Heading 1, Heading 2), parsing improves. If you manually format everything (bold, font size), parsing can struggle.

The practical difference: with PDFs, what you format is what parsers see. With Word, parsers sometimes miss formatting cues and extract content incorrectly.

This is why resume templates matter. Good templates use consistent formatting that parsers recognize: standard section headings, clear date formats, simple bullet structures. Whether you export as PDF or Word, that structure helps parsing.

Export quality matters

The best format is useless if the export is bad.

Common export mistakes:

• Low-resolution PDFs: Text looks blurry when printed or zoomed. Export at high quality (300 DPI for print, or use vector-based export when possible).
• Missing fonts: PDFs should embed fonts, but some exports don't. If a recruiter doesn't have your font installed, text might render differently.
• Broken layout: Complex formatting (tables, columns, text boxes) can break during export. Keep formatting simple and test the exported file.

A resume builder with proper export handles this automatically. When you export to PDF, fonts are embedded, resolution is correct, and formatting stays intact. You don't have to configure export settings or troubleshoot layout issues.

File naming matters too

Your resume file format matters, but so does the filename.

Bad names: "resume.pdf", "CV.docx", "document1.pdf"

Good names: "John-Smith-Resume.pdf", "Jane-Doe-Software-Engineer-Resume.pdf"

The filename should include:

• Your name (so it's findable if downloaded)
• Optional: role or keyword (if submitting to multiple jobs)

Keep it simple: no special characters, no spaces (use hyphens), no version numbers. "John-Smith-Resume-v3-FINAL.pdf" looks unprofessional.

A practical format checklist

Before submitting:

• Is the format what was requested? (Check the job posting)
• Does the exported file look correct when opened? (Test it yourself)
• Is the file size reasonable? (PDFs should be under 2MB typically)
• Is the filename professional and clear?

If you're using a resume builder, export handles most of this automatically. PDF exports are optimized for file size, fonts are embedded, and formatting stays consistent. You can export to PDF or PNG (for image-based submissions) without worrying about technical details.

The format choice decision tree

Here's a simple way to decide:

1. Did the posting specify a format? → Use that format
2. Is the ATS system known to prefer Word? → Use Word
3. Everything else → Use PDF

For 95% of applications, PDF is the right choice. It preserves formatting, works across platforms, and parses reliably in modern ATS systems.

The builder makes PDF export simple. You can export with one click, test the file immediately, and know it will look correct when recruiters open it. The templates are designed to export cleanly — spacing, alignment, and typography stay intact. For more on ATS compatibility, see how ATS systems work.
