PDF stability
A well-exported PDF preserves fonts, spacing, page breaks, and layout across common viewing environments.
Compare PDF and DOCX resume formats for layout stability, ATS parsing, editing, and employer instructions so you send the file type the hiring workflow expects.

Quick answer
Follow the employer's requested file type first. PDF is a strong default when no format is specified because it preserves layout across devices. DOCX can be appropriate when a recruiter or ATS explicitly requests Word. In either format, keep essential content as real text and test the final file before sending.
What matters most
A well-exported PDF preserves fonts, spacing, page breaks, and layout across common viewing environments.
Word files can be easier for some recruiting workflows to edit or parse, but rendering can vary by software and installed fonts.
If the employer specifies PDF, DOCX, or a portal text field, use that format regardless of generic advice.
Inside PortCV
PortCV's resume engine keeps the structured source separate from the final delivery file. Build and verify one source resume, then export the supported format appropriate to the application instead of treating the attachment as your editable master.

PDF is designed to preserve page appearance, which makes it useful for resumes with carefully tuned spacing, page breaks, and typography. Most modern recruiting workflows can handle text-based PDFs, but a scanned image PDF may not expose text reliably.
After export, try selecting a sentence in the PDF and verify links and fonts. A visually correct file can still contain broken text or missing characters.
Guide 02
Some recruiters, agencies, government systems, or older application tools may request DOCX. Word documents can be modified or normalized by the recipient, which is useful in some staffing workflows but can alter your visual formatting.
Use common fonts and review the document after conversion. Do not rename a PDF extension to .docx or vice versa; the actual file format matters.
Guide 03
Applicant systems differ. Clean text, recognizable headings, logical reading order, and a supported resume file type matter more than internet claims that every ATS prefers the same extension. Follow the application portal's accepted formats and instructions.
When people ask what format to save resume files in, the employer's instruction is the first answer. If none is given, a text-based PDF is often a practical default because it preserves presentation. A Word file is appropriate when DOCX is requested.
If the portal extracts a preview, inspect it when possible. Correct obvious parsing errors before submitting.
Questions people ask
PDF is often preferable for layout stability when no format is specified, while DOCX is appropriate when an employer or recruiter requests Word.
Many modern systems can read text-based PDFs, but ATS capabilities vary. Use a clean export and follow the employer's accepted formats.
Usually send the requested format rather than multiple attachments unless the recruiter asks for alternatives.
