Your file never leaves your device
Most online PDF tools upload your document to their servers and promise to delete it later. This one opens and edits the file inside your browser with the open-source pdf.js and pdf-lib libraries, so there is nothing to upload and nothing to delete.
Check it yourself: once this page has loaded, turn off your Wi-Fi. The tool keeps working.

Frequently asked questions
How do I add a stamp to a PDF?
- Add the PDF above, pick a stamp such as Approved or Paid, then click the page where it should go. Drag it into place, resize it from the corner, and press Download PDF.
Which stamps are included?
- Approved, Paid, Received, Reviewed, Final, Draft, Copy, Confidential and Void, each with an optional line showing today’s date. You can also upload your own image.
Can I use my company seal or logo as a stamp?
- Yes. Choose Upload an image and pick a PNG or JPG of your seal or logo. A PNG with a transparent background sits cleanly on the page; you can make one from a photo with Signature from Photo.
Is my PDF uploaded?
- No. The PDF and any image you add are processed in your browser and never sent to our servers. Once the page has loaded you can turn off your Wi-Fi and it still works.
Can I stamp several pages?
- Yes. Click on each page where a stamp should go. Every stamp can be moved, resized or removed before you download.
Does a stamp count as an approval or signature?
- A stamp is a visual mark; it does not record who placed it. When you need a record of who approved or signed a document and when, send it with an e-signature service instead.
