Batch Watermark
Apply the same text or image watermark to a batch of PDFs in one operation — each file processed locally in your browser under the Pro plan.
Files are processed locally in your browser — no upload is required for this tool.
Frequently asked questions
How do I watermark multiple PDFs at once?
Open the Batch Watermark tool (Pro plan), add your PDF files, set your watermark text or image and position, and run. Each file is saved with the watermark applied.
Is batch watermarking available on the free plan?
No. Batch processing requires the Pro plan. Single-file watermarking is free.
Can I use a logo image as the watermark?
Yes. You can use a text watermark or upload a PNG/JPG image to use as a watermark across all files in the batch.
Are the files uploaded to process the watermark?
No. Every file in the batch is processed locally in your browser — nothing is sent to a server.
Is it safe? Are my files uploaded?
These tools run locally in your browser — for supported local operations your files are not uploaded to a server. Processing the document on your own device avoids sending it to a third party.
