Your documents
StampAPDF processes PDF files entirely inside your web browser. When you merge, split, rotate, stamp, watermark, or convert a document, the file is never uploaded to our servers — the work happens on your own device and the result is saved directly back to your device.
Saved stamp & signature images
The Stamp & Sign tool lets you save small images (such as a signature or company stamp) to a library so you can reuse them. These images are stored in our database so they are available on your next visit. Do not save images you are not comfortable storing; you can delete any saved image at any time using the × button in the library, which removes it from our database.
Analytics and advertising
We may use third-party advertising (such as Google AdSense) to keep StampAPDF free. Advertising partners may use cookies or similar technologies to serve ads based on your interests. You can learn how Google uses data at policies.google.com/technologies/partner-sites and opt out of personalised advertising at adssettings.google.com.
Data we do not collect
We do not require accounts, do not collect names or email addresses, and do not see the contents of the PDF files you work with.
