Watermark Questions

Yes. Upload up to 100 PDFs (or drag an entire folder), select Add Watermark, configure the text and appearance, click Run. Every page of every file gets the watermark. All results are delivered as a single ZIP.
In one batch run, all files share the same watermark settings. For different watermarks on different files, run separate batches — each takes seconds to configure.
The watermark is burned into each page as part of the PDF content stream. It's not a removable annotation overlay. For maximum security, combine with the Flatten to Image operation to make the PDF a pure image-based document.
Online: up to 100 files per batch. Desktop app (Windows): unlimited files with no size restrictions, fully offline.
