Frequently asked questions

Can I sign a PDF with this?

Yes — click Sign, draw your signature on the pad with mouse or finger, place it on the page, resize and download. The signature is embedded into the PDF itself.

Can it edit text that's already in the PDF?

No browser-only tool can truly rewrite embedded PDF text — that requires desktop software like Acrobat. What you can do here: white-out the old text and type the correction over it, which is how most online editors handle it too.

Is whiteout a real redaction?

Visually yes, but the text underneath may still be technically extractable from the file. For genuinely sensitive redaction, white-out and then run the file through our PDF Toolkit's Compress (which rebuilds pages as images, destroying the hidden layer).

Does typed text support all languages?

Added text uses the PDF-standard Helvetica font, which covers English/European characters. For Hindi or other scripts, write the text as an image (screenshot) and place it with the Image tool.

Are my contracts uploaded anywhere?

No. Rendering, editing and saving all happen in your browser tab.
