PDF Editor

Write on top of a PDF, cover content with white boxes, and add images or your signature. The original content stays as it is, so the result stays sharp.

Cover boxes only hide content visually. The original text underneath stays in the PDF, so if you need to fully remove personal information, run the saved file through PDF Compress in Strong mode, which rebuilds each page as an image.

Your files never leave this device

When it helps

Printing a form just to write your name and date, then scanning it back in, takes time. With this tool you can type directly onto the PDF and draw your signature in place.

Your edits are saved as a layer on top of the original pages. The original text and graphics stay untouched, so everything remains sharp when zoomed and the file barely grows. English text uses a built-in font. If you type Korean, the NanumGothic font is embedded, adding about 0.7MB.

To fix a wrong word, cover it with a white box and type the correction on top. You can also extract all text from the document and save it as a TXT file.

FAQ

Can I edit the existing text directly?

Not directly. Cover the original text with a white cover box and type new text on top of it. This works well for most form and document fixes.

Does a cover box securely remove content?

No. The content is hidden on screen and in print, but the original text is still inside the PDF and can be copied or extracted. To remove sensitive data completely, save the file and run it through PDF Compress in Strong mode to rebuild the pages as images.

How do I add a signature?

Press Signature, draw in the box with your mouse or finger, then press Insert. It is added as a transparent PNG, so it sits naturally on the document. You can also add a saved signature image with the Image button.

Can I edit rotated pages?

Positions follow what you see, but on pages rotated by 90 degrees the added text may follow the page original direction. Fix the rotation first with PDF Organize, then edit.

Are my edits saved automatically?

No. Closing the page discards your edits, so always download the PDF with the save button when you are done.
