How do I watermark multiple PDFs at once?
Open Batch Watermark, add your PDFs, set the watermark text or image and its position, then run it. Each output is saved locally with the watermark applied.
Batch Watermark
Apply the same text or image watermark to a batch of PDFs in one operation. Every file is processed locally in your browser.
Frequently asked questions
Is batch watermarking free on the web?
Yes. Batch watermarking is free in the CyvoDocOps web app and needs no account.
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.
