Add a Logo to a PDF
Stamp your logo onto every page — pick the corner, the size and the opacity. A PNG with a transparent background sits cleanly over the content.

Who uses this tool
🔒 Your files never leave your device
There is no upload step to worry about, because there is no server. The file you choose is processed by your own browser, on your own device, and the result downloads straight from its memory. Once this page has loaded, the tool keeps working with the internet disconnected — try it in airplane mode. Unlike sites that promise to “delete your files after one hour”, there is nothing to delete: your file was never sent anywhere. See how to verify this yourself →
💡 Tips for the best result
- Use a PNG with a transparent background — a white box around a logo is the most common mistake.
- 10–20% of page width is a tasteful corner logo; 40%+ at low opacity works as a brand watermark.
- For a text watermark like CONFIDENTIAL, use the watermark tool instead.
Frequently asked questions
Is my document or logo uploaded?
No — the stamping happens in your browser; both files stay on your device.
Can I put the logo on only the first page?
Currently it stamps every page. Split the PDF, stamp the first part, and merge back for first-page-only branding.
Will the logo look sharp when printed?
The image is embedded at its original resolution — use a logo of at least 600 px width for print.
