This app allows you to add watermarks to PDFs and save them as PDF or image (JPEG).
You can use all features for individual pages without needing to register or log in.
When sharing PDFs with clients or publishing them online, you can check metadata, annotations, and bookmarks.
You can also decide whether to keep these elements during conversion.
All processes are done locally on your device, and no PDF or operation data is sent to our servers.
