Choosing the right file format for your resume helps preserve formatting and pass ATS. In most cases, PDF is preferred unless the employer asks for Word.
PDF preserves your layout, fonts, and spacing across devices. It is widely accepted and often preferred by employers. Many ATS can parse PDFs. Use PDF when the job posting does not specify a format or when it says "PDF preferred."
Word (.docx)
Use Word when the employer explicitly asks for an editable document (e.g., "Submit in Word"). Some employers or recruiters prefer Word so they can edit or add notes. If the posting says "Word" or "editable format," use .docx.
ATS and Formatting
Both PDF and Word can work with ATS when the resume is formatted simply: clear headings, standard fonts, no complex graphics or columns. Avoid text boxes, headers/footers for critical content, and images that might break parsing.
Best Practice
Default to PDF unless the employer asks for Word. Use a clear file name: FirstName_LastName_Resume.pdf or .docx. If the posting does not specify, PDF is usually the safer choice.
