How to edit a PDF
- Choose your PDF and press Open PDF editor.
- Pick a tool: Edit text (click existing text), Add text, Whiteout, Highlight, Shape, Draw / Sign or Image.
- Drag objects to move them; use the corner handle to resize; change font, size, colour, bold and italic in the bar above the pages.
- Press Download PDF. You can keep editing and download again.
Good to know
- Fonts: PDFs usually contain only the letters they use, so new text is written with the closest standard font — Helvetica/Arial, Times or Courier — at the original size and colour. For Arial, Helvetica, Times New Roman and Courier documents the result is identical.
- Hidden original text: edited text is covered, like in other online editors. Tick Remove hidden original text before downloading to turn edited pages into images so the old words are gone for good (useful for redacting).
- Scanned PDFs have no real text — use Whiteout plus Add text, or run OCR first.
- Standard PDF fonts support Latin characters; other scripts are replaced with "?".
Is it safe?
Yes. The whole editor runs in your browser with PDF.js and pdf-lib, so your document is never uploaded to a server.
Frequently asked questions
Can I change the existing text of a PDF?
Yes. Choose "Edit text" and click any line of real (not scanned) text, then type.
Will the font be exactly the same?
The size, colour, position, bold and italic are kept, and the closest standard font family is used. Documents set in Arial/Helvetica, Times or Courier look identical; for other fonts the new words use the nearest match.
Can I sign a PDF?
Yes — use Draw / Sign to draw your signature, or insert a signature image.
Is there a page or size limit?
Up to 300 pages and 100 MB.
Is it free and private?
Yes, it is free, needs no sign-up and your file never leaves your device.
