Write on PDF od CodeKP

Open any PDF in Firefox and instantly type, draw, sign, highlight, save or print. Works completely offline, with no uploads, no accounts, and no watermarks.

A free PDF editor that runs entirely in your browser. Fill in PDF forms, annotate documents, add your signature and print, without sending a single file to anyone.

WHAT YOU CAN DO

• Type anywhere on a PDF. Choose the font, size, colour, bold, italic, underline and strikethrough, or put a coloured background behind your text.
• Write in a handwriting font when a form should look filled in by hand rather than typed.
• Drag out a text box for longer notes and let the words wrap inside it.
• Fill in forms and paperwork on screen instead of printing them out and writing by hand.
• Select words on the page and highlight, underline or strike them through in one click.
• Highlight text by dragging across it, in any colour.
• Draw freehand with the pen, for a circled figure or a scribbled note in the margin.
• Draw rectangles, circles, lines and arrows to mark up a page.
• Add tick and cross marks for quick approvals.
• Sign PDFs. Draw your signature with a mouse, trackpad or touchscreen, or upload a photo of your signature on paper and have the background removed automatically.
• Search the whole document with Ctrl+F, however many pages it has.
• Undo and redo, rotate the view, zoom, and clear everything in one click.
• Every shortcut is one keystroke away: press ? for the full list.
• Print straight to your printer, or save a finished copy to your computer.

BUILT FOR REAL DOCUMENTS

• Opens documents with thousands of pages without slowing down, because only the pages near your screen are rendered.
• Your notes are written into the PDF as real text and real vector shapes, not as a screenshot, so printed output stays sharp at any size.
• Password-protected PDFs are supported. You are asked for the password, then you can annotate as usual. Saving writes an unlocked copy: the password and restrictions are removed from that file. Save shows a one-time warning before the download. Printing decrypts the PDF in memory for the print dialog; it does not download a file.
• Notes are saved automatically and come back the next time you open the same document.

COMPLETELY PRIVATE

• No uploads. Your PDFs never leave your computer.
• No account, no sign in, no subscription.
• No watermarks on anything you print or save.
• No ads, no trackers, no analytics.
• Works offline.

Every PDF is processed locally inside Firefox. There is no server involved at any point.

WORKS WITH PDFS FROM ANYWHERE

Links you click, files on your computer, PDFs generated by a web page, and finished downloads. If a PDF ever slips through, the toolbar button pulls it into the editor.

You can turn the whole thing off at any time from the toolbar button, and a single click sends any document back to Firefox's normal PDF viewer.
