Edit PDF Online – Add Text, Sign & Annotate

About PDF Toolkit

Add text, a handwritten signature, highlights, white-out boxes, and images on top of any PDF page, then download the result. Nothing is uploaded and there is no watermark.

This editor overlays your changes on the existing page, so the original text and layout stay intact and selectable. It is ideal for filling forms, signing agreements, marking up drafts, and redaction-style white-out.

Every edit is applied in your browser with no server involved, which matters for contracts, medical forms, and anything with personal data.

What you can use it for

  • Fill in and sign a PDF form without printing it.
  • Add your signature and date to an agreement.
  • Highlight key clauses before sending a document to a colleague.
  • White-out an account number or address before sharing a statement.
  • Drop a logo or stamp image onto a page.

Frequently asked questions

How can I edit a PDF for free without signing up?

Add your PDF, use the Text / Draw / Highlight / White-out / Image tools, then click Apply & download. It is free, with no account and no watermark.

Can I edit the existing text in a PDF?

You can add new text on top of the page, but rewriting the document's original text is not supported — this is an annotation and markup editor. Use white-out to cover text you want to hide, then add new text over it.

Is white-out the same as redaction?

It draws an opaque box over the content. The underlying text still exists in the file, so treat it as visual redaction, not secure removal.

Are my PDFs uploaded?

No. Editing and exporting run entirely in your browser; your file never leaves your device.

Can I sign a PDF here?

Yes. Use the Draw tool to draw your signature with a mouse, trackpad, or finger, then place and resize it on the page.

Does it work on mobile?

Yes — the editor supports touch, so you can sign and annotate on a phone or tablet.
