Images, text, Markdown, HTML, CSV, RTF, EPUB, unencrypted legacy MOBI, docx, xlsx, xls, and pptx are converted locally in the browser. Legacy doc/ppt, encrypted MOBI, and complex Kindle formats need a future server-side converter.

About this tool

PDF to PDF regenerates a standardized copy when a document has unusual structure, weak compatibility, or needs consistent output. It reads existing pages into a new PDF container but cannot guarantee repair of every corrupt object, missing font, or complex interactive form.

Regeneration can change metadata, bookmarks, annotations, forms, attachments, digital signatures, and accessibility tags. Documents requiring legal validity, long-term archiving, or print color accuracy need dedicated signature, preflight, or PDF/A tooling.

How to use it

  1. Open the original first

    Confirm page count, orientation, and critical content and note bookmarks, forms, or signatures.

  2. Generate a new copy

    Keep the page open while all pages are processed.

  3. Compare every important feature

    Check page count, text, images, links, and special behavior before replacing a working copy.

Supported range and limits

Accepted sources
Word, Excel, PowerPoint, EPUB, MOBI, JPG, PNG, WebP, TXT, Markdown, HTML, CSV, RTF
Layout fidelity
DOCX keeps common paragraph styling, tables, and images; HTML uses embedded and inline CSS; Excel keeps worksheets, table borders, merged cells, and common row and column sizing; PowerPoint remains content-focused
Fonts
Uses fonts available to the browser; a font not installed locally falls back to a substitute
From images
Each image becomes its own page, sized to the image's aspect ratio
Lost in conversion
Macros, complex fields, comments, tracked changes, Excel charts and floating images, interactive form fields, and slide animations
Where it runs
Entirely in the browser; the source document is never uploaded

When you would use it

  • Improving reading compatibility

    Create a simpler copy of an ordinary document that some viewers cannot open reliably.

  • Normalizing a workflow input

    Produce a version readable by the current toolchain before merging, splitting, or watermarking.

  • Standardising office documents for distribution

    Once Word, Excel and PowerPoint files are PDFs, recipients need no matching software and the layout does not shift between versions.

What to know before you start

  • Digital signatures depend on file bytes and normally become invalid after regeneration.
  • Password-protected or severely damaged PDFs may not be readable or fully reconstructable.
  • Ordinary PDF regeneration does not establish PDF/A conformance.

Frequently asked questions

Does Convert to PDF upload my files?
No. Images, text, Markdown, HTML, docx, xlsx, xls, and pptx are converted locally in the browser in this first release.
Does Office to PDF preserve the original layout?
The current browser version extracts docx paragraphs, Excel table rows, and pptx slide text before generating a PDF. It is useful for quick archiving. Complex layouts and legacy doc or ppt files will need a future server-side converter.
How much EPUB and MOBI support is included?
EPUB is read from the book package and XHTML spine order before generating a PDF. MOBI currently supports text extraction from unencrypted legacy MOBI/PalmDOC files; encrypted MOBI, AZW/KF8, and complex Kindle files need a server-side converter.
Can I convert files in bulk?
Yes. Upload multiple files, then download each converted PDF individually or export everything as a ZIP.
Which PDF tools are planned next?
Planned tools include merge, split, compress, image conversion, edit, annotate, sign, watermark, encrypt, decrypt, and OCR.
Why does the layout differ from the original?
DOCX and HTML are rendered into PDF by the browser rather than the original application. Common styling and images are retained, but font availability, complex fields, line-height calculation, and pagination can still differ from Word. When layout must match exactly, use the source application's own Export as PDF.
Why did the fonts change?
The document used a font your browser cannot access, so rendering fell back to a substitute. Install the font on the system, or switch the source document to a widely available one.
