Bulk PDF Watermark
Apply the same watermark across a whole batch of PDFs in one go.
One stamp, every file
When a watermark needs to go on more than one document — a set of proposals all marked DRAFT, a folder of files stamped CONFIDENTIAL, a batch of proofs carrying your name — doing them individually is repetitive. This applies the same watermark to every PDF you drop in, so the whole set comes out consistently marked.
Set the text, opacity and angle once, and it is stamped across all of them.
Consistency is the benefit
The point of batching is not just speed, it is uniformity — every file ends up with an identical mark in the same place, which looks deliberate rather than ad hoc. Keep it light and diagonal so each document stays readable, and remember the whole batch is processed on your device, so sensitive files are never uploaded to be stamped.
How to watermark many PDFs at once
- Drop in all the PDFs you need to stamp.
- Set the watermark text and its look once — position, opacity and angle.
- Process the whole batch and download them together as a ZIP.
One setting, every file
When you have a folder of documents to send out — proposals, reports, photo proofs — watermarking them one at a time is a chore. Batch watermarking applies the same mark to every file in a single pass, so a hundred PDFs take about as long as one.
Keep the wording generic enough to fit all the files (your brand name or CONFIDENTIAL) rather than something specific to one document.
Common questions
Do all files get the same watermark?
Yes — that is the point of batch mode. For different marks, run separate batches.
How many PDFs can I do at once?
As many as your device's memory allows; larger batches simply take a little longer since it all runs locally.
Are the originals changed?
No. You download new, watermarked copies and your source files stay untouched.
Can I watermark many PDFs at once?
Yes. The same watermark is applied to every file you add.
Will the watermark look the same on each file?
Yes. One set of settings is applied across the batch for a consistent result.
Are my files uploaded?
No. The batch is watermarked in your browser.
