Add Stamp to PDF Online

Add Stamp to PDF Online works in the browser with local processing, preview and download. Files stay on your device.

Files are not sent to a server. Processing runs in your browser, and the queue handles one file at a time so the device stays responsive.

Exact coordinates and batch values

Add at least one PDF and one image file. The stamp can be dragged on the thumbnail or in the large preview; exact coordinates open separately. The insertion is added as a regular image, with no e-signature or external services.

How to use it

Add the files, choose the tool settings and check the first result before processing the full queue.

Recommended settings

Start with the default values, then adjust one control at a time and review the preview. On phones, process fewer large files in one batch.

Privacy

Your files are not uploaded to a server. The editor runs in your browser with local libraries from this site.

Limits

Large images can take longer on phones. If the browser slows down, process fewer files at once or choose a smaller output format.
