Why PDF is better than .docx for sharing documents
A Word document displays differently depending on the version of Word, the operating system, the installed fonts, and the page size configured on the recipient's machine. A carefully formatted resume that looks perfect on your MacBook can arrive with shifted margins, substituted fonts, and broken table borders on a Windows PC running an older Office version. PDF locks the layout: every character, every line break, every image position is fixed as absolute coordinates. The recipient sees exactly what you intended regardless of their software.
PDF is also universally readable — every modern browser opens PDFs natively, no application install required. For anything you don't want edited (resumes, invoices, contracts, reports), PDF is the correct format.
What Word features survive PDF conversion
- Text and formattingBold, italic, underline, font size, and color all convert reliably. Paragraph spacing and indentation are preserved as fixed positions in the PDF coordinate system.
- Images and shapesEmbedded images convert with no quality loss. Shapes and drawing objects are rasterized or preserved as vector paths depending on the converter.
- HyperlinksClickable links are preserved in the PDF and remain clickable in PDF readers. Useful for documents with references or navigation.
- What does NOT convertComments, track changes, and revision history are not included in the PDF output (by design — you typically don't want reviewers seeing these). Macros and form fields may or may not convert depending on the converter.
The font issue that makes PDFs look wrong
If your Word document uses a font that isn't embedded in the PDF output and isn't installed on the recipient's machine, the PDF reader substitutes a fallback font — typically a generic serif or sans-serif. This changes character spacing and can reflow text or break the layout. Good converters embed all fonts used in the document into the PDF file, making it self-contained. If your PDF looks different on another machine, open it in Acrobat Reader, go to File → Properties → Fonts, and verify all fonts are listed as "Embedded Subset".
Resume DOCX to PDF — what job boards and ATS expect
Most job applications ask you to upload a resume. Uploading a .docx file risks the formatting breaking in the hiring manager's version of Word. Uploading a .pdf locks your layout permanently and makes it ATS-safe. Here's what each major platform expects:
| Platform | Accepted formats | Notes |
|---|---|---|
| LinkedIn Easy Apply | PDF (recommended), DOCX | PDF renders consistently in recruiter inboxes |
| Indeed | PDF, DOCX, RTF, TXT | ATS parses all; PDF preserves visual layout |
| Greenhouse (ATS) | PDF (recommended) | Most Greenhouse clients prefer PDF for ATS parsing |
| Lever (ATS) | PDF, DOCX | PDF avoids font-substitution on Lever preview |
| Workday (ATS) | PDF, DOCX | Some Workday implementations parse DOCX poorly — use PDF |
| Direct email to recruiter | Always PDF — DOCX may arrive reformatted on mobile | |
| Google Careers | PDF, DOCX | PDF preferred to prevent font rendering issues |
When converting your resume, check that the output PDF uses standard fonts (Calibri, Arial, Times New Roman, Georgia). These are universally embedded and display consistently on every device. Decorative fonts from Google Fonts or Adobe Fonts are sometimes not embedded — the font section of your PDF properties (File → Properties → Fonts in Acrobat Reader) will list "Embedded Subset" for any correctly embedded font.
