Why does my PDF look different from my Word file?

Word renders with the fonts installed on your machine. PDF embeds fonts. Subset embedding (the default) keeps file size small but can subtly shift glyph widths. If you need pixel-identical, set Word to fully embed fonts in Options → Save.

Yes — with Acrobat Pro, PDFescape, or by converting to Word and back. The 'PDF is uneditable' myth comes from default viewers like Preview that hide the editing tools.

Which format is smaller?

Usually PDF, because fonts are subset-embedded and images can be downsampled. A 30 % size reduction is typical for Word → PDF.

Can I sign a PDF without printing it?

Yes. Acrobat, Preview (Mac) and most PDF readers support drawn signatures. For legal validity, use a Digital Signature (PKI cert).

Which format works best on phones?

PDF. Word's mobile reflow is improving but still inconsistent. PDFs look the same on every phone.

Should I send a resume as PDF or Word?

PDF — every ATS in 2026 reads PDFs perfectly, and you guarantee the recruiter sees the formatting you designed. Send Word only if the job posting explicitly asks.

PDF vs Word: When to Use Each Format (2026)

Word documents and PDFs solve different problems. Send a contract as .docx and the recipient can secretly edit a clause; send a draft article as PDF and the editor can't fix typos without exporting twice. Choosing the right format for the right moment saves embarrassment, security incidents and hours of formatting cleanup. Here's the practical 2026 rulebook.

What each format is actually for

Word (.docx) is an editable document. It carries structure (headings, paragraphs, tables, lists) and visual layout, but it's primarily a working file. Two people on different Word versions or Word vs Google Docs will see slightly different layouts.

PDF (.pdf) is a fixed-layout document. Pages render pixel-identical on every device — that's its entire purpose. Fonts are embedded; layout doesn't reflow. It's hard to edit; that's a feature, not a bug.

When to use Word

Drafting and collaborating — edit, comment, track changes.
Templates that recipients need to fill in (CVs, forms, briefs).
Anything that will go to a typesetter, translator or proofreader.
Long documents that need a clickable table of contents you'll regenerate.
Reports where the data tables update from Excel via a linked field.

When to use PDF

Final delivery — invoices, contracts, certificates, official letters.
Print-ready files — brochures, posters, decks.
Anything legally binding — PDFs are accepted in court as the 'final' version.
Files going to recipients you don't know — guarantees they see the layout you intended.
Forms you want filled in once and returned (PDF forms with form fields).
Anywhere you need to lock down editing, copying or printing (PDF permissions).

What you lose converting Word → PDF

Comments, track changes, hidden text and Word-specific revision history are stripped (some are converted to PDF annotations; others are dropped silently). Macros and embedded VBA disappear. Linked Excel data is flattened to its current values.

What you lose converting PDF → Word

Original Word layout was destroyed when you exported to PDF; the converter rebuilds it from the visual representation. Expect: page breaks in odd places, tables converted to fixed-position text boxes, fonts substituted if the original isn't installed, footnotes turned into footer text. Manual cleanup is almost always required.

Step-by-step: Word → PDF the right way

1Inside Word, run the Accessibility Checker (Review tab) to add alt text to images.
2Update all fields (Ctrl+A then F9) so dates and references show the latest values.
3File → Save As → PDF. Tick 'Document properties' and 'Document structure tags for accessibility'.
4Check the resulting PDF in any viewer — colours, fonts and layout should match.
5If the file is over 5 MB, run it through a PDF compressor before emailing.

Step-by-step: PDF → editable Word

1Open the EazyAITools PDF → Word converter.
2Upload the PDF (text-based, not a scanned image — for scans, use the OCR tool first).
3Download the .docx output.
4Open in Word. Fix table formatting, page breaks and header/footer placement manually — budget 5 minutes per 10-page document.
5Save as .docx (modern format) — never .doc, which strips modern features.

Security & permissions

PDFs support two layers: a user password (required to open) and an owner password (required to edit, print or copy). Word documents support password-on-open (decent encryption since Office 2007) but not granular permissions.

If you're sending a contract: PDF + owner password to block editing. If you're sending a template: Word with a 'Read-Only Recommended' flag (easy to override, but signals intent).
