About Word to PDF

PDFBolt converts Microsoft Word documents to PDF directly in your browser, with two conversion modes tuned for different use cases. Smart mode uses our document intermediate representation for fast conversions (~2–5 seconds) with editable text and ~80% layout fidelity. High Fidelity mode renders the document using the browser's layout engine for ~95% Adobe-quality visual reproduction — text becomes part of the rendered image, but the result looks indistinguishable from the original Word document.

Because both modes run entirely in your browser, your Word file is never transmitted anywhere. This is especially important for confidential documents — contracts, HR paperwork, financial records, legal filings — where handing the file to a third-party converter is unacceptable.

The output PDF is universally compatible — renders correctly in Adobe Acrobat, Chrome, Firefox, Safari, and every major PDF viewer. File sizes are optimized automatically.

How it works

  1. Upload your .docx or .doc fileDrag the file into the converter, or click to browse. Works with Word 2007+ (.docx) and legacy Word 97-2003 (.doc).
  2. Choose Smart or High FidelitySmart mode is fast and keeps text selectable (best for most documents). High Fidelity produces pixel-perfect visual match (best for résumés and designed documents).
  3. Click ConvertConversion runs locally in your browser using WebAssembly and the native rendering engine. Progress shows in real time.
  4. Download your PDFThe resulting PDF opens in any PDF viewer — Adobe Acrobat, Chrome, macOS Preview, mobile apps.

When to use Word to PDF

Submitting résumés to job applications
Applicant tracking systems prefer PDF. Convert your Word résumé to a pixel-perfect PDF that looks exactly the way you designed it — no font substitution surprises.
Locking in formatting before emailing a contract
Avoid the situation where the recipient's Word version re-flows your contract. PDF preserves page breaks, signatures, and layout for every reader.
Academic paper submissions
Most journals and conferences require PDF submissions. Convert your formatted manuscript with confidence that fonts and equations render identically.
Archiving finished documents
PDF is a long-term format that renders consistently decades from now. Convert completed Word documents to PDF before archiving so they never depend on a specific Office version.

Frequently asked questions

Which mode should I pick — Smart or High Fidelity?
Start with Smart — it is fast and keeps text selectable/searchable (important for accessibility and archiving). Switch to High Fidelity if the output layout differs from your Word source (unusual fonts, tight designs, tables with complex layouts).
Does it work with .doc files (the old Word format)?
Yes. Both .doc (Word 97–2003) and .docx (Word 2007+) are supported. If you have .odt (OpenDocument), save it as .docx from LibreOffice first.
Will Microsoft fonts be preserved?
In Smart mode, common Microsoft fonts (Calibri, Cambria, Arial, Times New Roman) are substituted with their open-source equivalents (Carlito, Caladea, Arimo, Tinos) which have identical metrics — the result looks visually identical. In High Fidelity mode, whatever your browser displays is what gets rendered.
Is the output PDF searchable?
Yes in Smart mode — text is embedded as real PDF text, so Ctrl+F works and screen readers can read it. In High Fidelity mode, text becomes part of an image and won't be searchable.
Why is the file size different from my Word source?
PDFs include embedded fonts and compressed page streams, so file size depends on content — simple text documents come out smaller than the Word source; documents with many images come out similar or larger. Use Compress PDF afterward if you need to email a smaller file.
Does this handle complex layouts like tables and images?
Yes for most cases. Smart mode handles tables, inline images, headers/footers, and page numbering well. For documents with tight visual design (e.g. magazine-style résumés), High Fidelity mode is more reliable.
