PDF or Word? What three ATS vendors document

Instead of an opinion, here is what Greenhouse, iCIMS and Workday say in their own documentation about resume files, and what USAJOBS says for federal jobs. Accepted types can vary by employer, so the upload box on the application has the final say. Whichever type you send, it should be a document with real, selectable text, not an image of one.

Our summary of each system's own documentation, read October 11, 2026. Documentation changes, so check the source before you rely on it.

What the vendors say can trip up a resume parser

Greenhouse's help center lists formatting its resume parser may not interpret correctly, and says these issues may leave a partial parse that someone has to correct by hand. The list includes:

  • graphics, photos or word art
  • a resume uploaded as an image rather than a document
  • tables, headers and footers
  • your name and contact details in a header, footer or text box
  • a columned layout
  • no clear sections, and differing formats throughout each section
  • spaces between the letters of a word
  • incomplete job titles, such as "Sr. Account Exec" instead of "Senior Account Executive"

Workday's documentation says parsing results can vary with a resume's format and the order of its words, and that resumes without images or image-based styles give the best results. Greenhouse adds that parsing can make mistakes, so review every field it fills in before you submit.

FAQ

Frequently Asked Questions

A layout a resume parser can read into the right fields. Greenhouse's help center lists formatting its parser may not interpret correctly, including graphics, photos or word art; tables, headers and footers; a name and contact details in a header, footer or text box; a columned layout; and a resume without clear sections. Workday's documentation says resumes without images or image-based styles give the best parsing results. So use one column and clear section headings such as Experience, Education and Skills, keep your name and contact details in the body of the page, and leave out tables, graphics and photos.
