PDF or DOCX: Which File Format Should You Use for an ATS Resume?

PDF or DOCX: The Short Answer

Follow the job posting first. If it names a format, use that one. If it accepts both, upload a DOCX when the form reads your resume into fields, and send a PDF when a human will open the file. Both formats are accepted by the ATS platforms that document their rules, so the file type is rarely what decides whether your resume parses. The layout inside the file usually matters more.

Advice online conflicts because some guides say PDF is always safer and others say DOCX always is. The sections below separate what vendors and employers have published from what is only opinion. For how the parser itself reads a file, see how an ATS resume parser reads your resume.

Which File Types Do Major ATS Platforms Accept?

Every ATS below documents support for both PDF and Word files. The details differ in size limits and in which older formats they accept. This table reflects each vendor’s help center as of October 2026, so check the upload form itself, because individual employers can restrict formats.

None of these lists include Google Docs, Apple Pages or Canva project files. Export to PDF or DOCX before you upload.

Which Format Does an ATS Parse More Accurately?

DOCX has a slight edge in published employer guidance, while PDF has the edge for keeping your design intact. Roche’s candidate guidance recommends .docx or .pdf, says PDFs hold their formatting best, and says .docx is the format ATS systems parse most accurately (Roche). A DOCX stores its text in a structured, XML-based package, so a parser has little to guess about where text starts and ends.

That edge is small when the PDF is built correctly. A PDF exported from a word processor carries a text layer the parser can read, and Greenhouse and Lever both list text-based files as parseable. The difference appears when a PDF was scanned, screenshotted or flattened into an image. Greenhouse names an image upload as a cause of an unsuccessful parse, and Lever states it cannot parse image files.

Some guides argue PDF is the better ATS format because it never shifts layout between devices. That is true for display, but it does not change how the text is extracted. Display fidelity matters to the person who reads your resume. Extraction accuracy matters to the parser.

When Is a PDF the Better Choice?

Choose PDF when a person is the reader and the layout matters. That covers emailing a recruiter or hiring manager, sending a resume through a messaging app, attaching it to a LinkedIn message and uploading to a portal that states PDF as the required or preferred type. A PDF looks the same on every device and cannot be edited by accident.

Choose PDF over DOCX in these cases:

• The posting says “PDF” or lists PDF as the only accepted type.
• You are sending the file directly to a person, not into a form that fills fields.
• Your DOCX shows different spacing or fonts when opened in another program or on another operating system.

Roche’s guidance also notes that many candidates keep two versions of their resume: a plain one for parsers and a more designed one for people (Roche). A single clean, single-column resume can serve both purposes, which is the approach we describe in our guide on how to create a resume.

What Matters More Than the File Format?

Layout and file hygiene cause more parsing failures than the choice between PDF and DOCX. Roche advises avoiding tables, text boxes, logos, images, graphics, columns, and header or footer content, because some systems read columns straight across the page and may drop text placed in headers and footers (Roche). Greenhouse’s own parse-failure article lists graphics, photos, word art, image-only uploads and files over 2.5 MB (Greenhouse).

Check these before you think about format:

1. One column. Put contact details, experience, education and skills in a single top-to-bottom flow.
2. Contact details in the body. Keep your name, email and phone out of the header, footer and text boxes.
3. Standard headings. Use labels such as Experience, Education and Skills.
4. Plain text for skills. Skill bars, icons and rating dots are graphics, not text.
5. A small file. Stay well under 2.5 MB, which is Greenhouse’s parse ceiling.

A format choice cannot rescue a resume that is too complicated to parse. The article on how an ATS resume parser reads your resume shows how a two-column layout can scramble text, and the ATS optimization category collects our other parsing guides.

Which Format Should You Pick in Each Situation?

Match the format to where the file is going. The table below gives a default for each case, and the posting’s instructions override every row.

If you are applying outside the United States, the file format advice does not change, but the document name may. See CV vs resume for how the terms differ by region.

How Can You Test Your File Before You Upload It?

Run a five-minute text test on the exact file you plan to upload. It approximates what a parser sees, though it does not reproduce any specific ATS. If the text comes out clean, you have removed the most common causes of a failed parse.

1. Select the text. Open the file and try to highlight a sentence with your cursor. If you cannot, the file is probably an image.
2. Copy and paste. Select all, copy, and paste into a plain text editor such as Notepad or TextEdit in plain-text mode.
3. Read the order. Check that the sections appear in the same order as on the page and that lines from different columns are not interleaved.
4. Look for missing pieces. Confirm your name, email and phone number appear. If they are missing, they were probably in a header, footer or text box.
5. Check the file size. Keep it comfortably under 2.5 MB for Greenhouse and under 5 MB for Workable.
6. Remove leftovers in a DOCX. Accept or delete tracked changes and comments so they cannot show up as stray text.

Run the test again after every export. A small layout edit can change how the file is built.

How Do You Export a Clean PDF or DOCX?

Export from the program where you wrote the resume, and do not scan, photograph or screenshot a printed copy. In Microsoft Word, use File, then Save As, then choose PDF or Word Document (.docx). In Google Docs, use File, then Download, then pick Microsoft Word (.docx) or PDF Document (.pdf) (TopResume).

Prefer .docx over the older .doc extension. TopResume notes that differences between Word versions and between Mac and PC can alter a resume’s formatting, and an older .doc file is more exposed to that. Keep one clean DOCX as your master file and export a fresh PDF from it whenever you edit, so the two versions never drift apart.

If you build your resume in a tool, check what it exports before you rely on it. The 7resume resume builder is designed around ATS-friendly, text-based output, and the same five-minute test applies to any file from any builder. If you are starting from a role-specific layout, the builder has pages for software engineers, data analysts, project managers, registered nurses and other roles.

Frequently Asked Questions

Is PDF or DOCX better for ATS?

Neither is universally better. Both are accepted by the major ATS platforms that publish their rules, and Roche’s guidance gives DOCX a small advantage for parsing accuracy. Use the format the posting requests, and fall back to DOCX when an upload form will read your file into fields.

Can an ATS read a PDF resume?

Yes, if the PDF contains real text. Greenhouse and Lever both document support for PDF files. A PDF made from a scan, a photo or a screenshot has no text layer, and Greenhouse and Lever both list image-based files as something they cannot parse.

Should I upload a .doc or a .docx file?

Use .docx. Greenhouse and Workday HiredScore still list .doc as accepted, but .docx is the current Word format, and TopResume warns that Word version differences can change formatting. Save as .docx unless the posting says otherwise.

What about Google Docs, Pages or Canva files?

Export them first. None of the vendor lists above include those native formats. Download a DOCX or PDF, then run the copy-paste test before you upload.

Does file size matter for an ATS resume?

Yes. Greenhouse accepts uploads up to 100 MB but cannot parse a resume larger than 2.5 MB, so a heavy file can attach to your profile with no extracted data. Workable limits resumes to 5 MB. Remove images and heavy graphics to keep the file small.

Should I send a PDF when I email a recruiter?

Yes, unless the recruiter asks for Word. A PDF keeps your layout fixed for a person reading it, and some staffing recruiters ask for a Word file because they edit resumes before forwarding them. Follow the request when there is one.
