Edit & annotate

Edit text in PDF online

Click on any line of your PDF and rewrite it, like in a word processor. windpdf edits the document's own text runs, the original font is preserved, and rotated text stays rotated.

Files stay private: PDFs and images are edited in your browser.

Original font preserved

windpdf reuses the font embedded in your document and embeds only the glyph subset you actually use, so edited text is indistinguishable from the original.

Rotated text supported

Text at any angle stays editable in place, the edit box, selection and highlights follow the rotation instead of snapping back to horizontal.

Runs in your browser

Editing is done by the MuPDF engine compiled to WebAssembly. Your file is processed on your device and only uploaded if you choose to save it to your drive.

The text editor, up close

This is what opens when you click Edit text: your own page, the editor's selection frame, and a floating bar carrying the fonts already embedded in the file.

Click the line, rewrite it

The blue frame and its handles are the editor's real selection chrome. You type, and windpdf rewrites the text run underneath instead of covering it with a white box.

What the edit leaves alone

Only the run you touched is rewritten. The rest of the page stream is copied through untouched.

A scan has nothing to edit yet

Scanned pages are images. Run OCR in editable mode first and the words come back as real text runs you can click into.

Rotated text edits at its own angle

Diagonal watermarks, rotated tables, vertical labels: the edit box, the selection and the highlights all follow the rotation instead of snapping back to horizontal.

Real PDF text editing, not an overlay

Most online "PDF editors" paint white boxes over your text and add new text on top. windpdf rewrites the actual text runs inside the page content stream: unedited text is left byte-for-byte untouched, and the edited run keeps its font, size and color.

Because the document's own embedded font is reused, there is no font substitution and no layout jump, the line you fix looks exactly like the lines around it.

A PDF page edited with windpdf: the original font is preserved and highlights follow the rotated text at the same angle

What you can do with the text editor

  • Fix a typo, a wrong date or an old price directly in the sentence
  • Delete a word or a whole text block, the surrounding layout is preserved
  • Move or resize a text block; paragraphs reflow inside the box
  • Edit rotated or vertical text without straightening it first
  • Copy-paste text while keeping the original formatting

Frequently asked questions

No. windpdf reuses the font already embedded in your PDF and embeds only the extra glyphs your edit needs. The edited text keeps the original typeface, size and color.

Yes. Rotated text runs stay editable at their own angle, the editing box, selection and highlights all follow the rotation.

A scanned page is an image, so there is no text run to edit. Run the OCR tool first to get a searchable or editable text layer, then edit it.

No. Editing happens in your browser with the MuPDF WebAssembly engine. The file only leaves your device if you explicitly save it to your windpdf drive.
