What inputs does PDF Watermark accept?

PDF Watermark accepts the file types listed in the tool UI. Convert unsupported formats first or use a related Tentaco tool.

Are files uploaded?

No. PDF Watermark processes the standard mode locally in your browser; Tentaco does not receive your input for that path.

Is there a file size limit?

Practical limits depend on your device and browser memory. Very large files may be slow or fail in PDF Watermark — shrink the file and retry.

How do I download the result?

After processing, PDF Watermark shows a download action. Save locally; Tentaco does not auto-archive to a cloud library.

Does it work on mobile?

Yes, PDF Watermark runs in mobile browsers. For very large media, desktop is often more comfortable.
