Yes. Switch to the "Image" tab, upload your logo (PNG recommended for transparency support), and adjust its size, opacity, and position. Your logo will appear cleanly on every page.
The watermark is embedded into the PDF pages as content. It cannot be removed by simply opening the PDF. Advanced editors may attempt removal, but for most practical purposes it is permanent โ especially in mosaic mode.
Yes. Use the "Apply To" dropdown to choose all pages, first page only, odd pages, even pages, or a custom range like 1-3, 5, 8-10. You can also browse every page in the live preview before downloading.
Completely safe โ because nothing is actually uploaded. The entire watermarking process runs inside your browser using JavaScript. Your file never touches any server. Safe for contracts, certificates, or financial statements.
Not directly. A password-protected PDF is encrypted, so it must be unlocked first. Use our free Remove PDF Password tool to unlock it, then come back here to add your watermark. If you want to protect the final file again, you can add a password afterwards with the same tool.
Yes. Add your text or upload your logo or signature, then drag it on the live preview to place it exactly where you want. With Mosaic turned on, the position you choose becomes the starting point of the tiled pattern, so you can shift the whole pattern too. Use the Reset button to go back to the 9-point position grid. The final PDF matches the preview.
