Watermark Image
Add a text or logo watermark to your own photos — choose the position, opacity and rotation, batch several at once, and download. Free, private and processed entirely in your browser.
Text watermark
Logo watermark (optional)
Watermarking happens in your browser — your images are never uploaded.
How it works
Each photo you add is drawn onto an HTML <canvas> scaled to fit your
screen so you can preview the watermark instantly. Your text is painted with the chosen
font, colour, opacity and rotation at the position you pick, and any logo is drawn on top
at the scale and transparency you set. When you click Apply watermark,
the tool repaints the watermark onto a fresh canvas at the image’s real resolution and
exports a downloadable file — so the mark stays crisp even on large pictures. The source
format is kept (JPEG, WebP or PNG) wherever possible. Because every step runs in
JavaScript on your own device, nothing is ever uploaded.
How to watermark an image
- Drop one or more of your own images into the tool.
- Type watermark text and/or upload a logo PNG.
- Set the font, size, colour, opacity, rotation and position.
- Click Apply watermark to render at full resolution.
- Download each image, or grab the whole batch as a zip.
Watermark your own work — honestly
A watermark is a simple way to label images you own: photographs you took, designs you made, product shots, screenshots for a tutorial, or proofs you send to a client before final delivery. A subtle © your name in a corner credits the work without spoiling it; a bold tiled mark across the whole frame makes a preview hard to lift and reuse. This tool is built for that legitimate use — watermarking images you have the right to mark. It is not for stamping your name onto someone else’s photo or removing an existing watermark.
Doing it locally keeps your files private and the workflow fast. There is no upload queue and no server holding your originals, which matters for unreleased product photos or personal pictures. Need to prepare the images further? Resize them with the resizer, shrink the file with the compressor, or change format with the converter.

Frequently asked questions
How do I add a watermark to an image?
Drop one or more photos, type your watermark text or upload a logo PNG, then adjust the size, opacity, rotation and position. The preview updates live; click Apply watermark to render each image at full resolution and download it.
Can I watermark several images at once?
Yes. Select multiple files and the same watermark settings are applied to every image. When there is more than one result the tool also bundles them into a single .zip so you can grab them all in one click.
Can I use my own logo as a watermark?
Yes. Upload a PNG (transparency is preserved) or any image as the logo, then set its position, scale and opacity. You can combine a logo and a text watermark on the same image, or use either on its own.
What does a tiled watermark do?
Choosing the Tiled / repeat position stamps the text diagonally across the whole image in a repeating pattern. That makes the mark much harder to crop out, which is useful for proofs, previews and contact sheets you share publicly.
Are my images uploaded to a server?
No. Everything runs in your browser with the Canvas API — the original photo, the logo and the finished watermarked file never leave your device. This tool is meant for watermarking images you own or are authorised to use.
Image Tools watermarks images entirely within your browser. Files are never uploaded.
