2. Preview
Add an image or PDF above to see a live preview of your watermark.
3. Text watermark
Optional: logo / image watermark
Layer a PNG, JPG or WebP logo on top of (or instead of) the text watermark.
4. Download
A single file downloads directly; multiple files are packaged into one ZIP. Every PDF page is watermarked — there's no page cap.
Built to be fast, private and eco-friendly
Because every image and PDF is processed on your own device, no file ever travels to a server — that means less network traffic, less server compute, and a lighter footprint than upload-based watermarking tools, on top of being quicker for you.
Lighter on the planet
No upload, no server rendering — your device does the work, so each watermark costs less energy than a round trip to the cloud.
Private by default
Files never leave your browser tab. Close the page and everything is gone — nothing was ever stored anywhere else.
No PDF page limit
Ten pages or a thousand — every single page in every PDF you add gets the same watermark, automatically.
Folder & batch upload
Select individual files or an entire folder in one go. Everything is watermarked and zipped into a single download.
Text and logo, together
Stack a text watermark with a logo image, each with its own position, size, rotation and opacity.
9-position placement & tiling
Pin the watermark to any corner or edge, or tile it diagonally across the whole page for stronger protection.

Frequently asked questions
Is there a page limit for PDF watermarking?
No. Every page of every PDF you add is watermarked — there's no artificial page cap, whether your document has 5 pages or 500.
Are my files uploaded to a server?
No. Watermarking happens locally in your browser using JavaScript. Your images and PDFs never leave your device.
Can I watermark a whole folder of images at once?
Yes. Use "Choose folder" to select every image and PDF inside a folder, or "Choose files" to multi-select individually. Everything is processed and packaged into one ZIP download.
Can I use a logo instead of text?
Yes. Upload a PNG, JPG or WebP logo — it can be applied alongside or instead of a text watermark, with its own position, size and opacity.
What file formats are supported?
JPG, PNG and WebP images, and PDF documents. You can mix formats in a single batch.
Is this really free?
Yes — no account, no watermark on the watermark, no page or file-count limits enforced by us.
