Add a watermark to your photos
Protect your photos or brand your work with a text or logo watermark — pick the corner, size and opacity and see the result live. Works on whole batches, and your images never leave your device.
100% private: files are processed in your browser and never uploaded to any server.
How it works
- Drop one or more photos into the box above.
- Type your watermark text and pick a font — or switch to Logo and upload your PNG — then set size and opacity, or drag the watermark anywhere on the live preview.
- Click Apply and download the watermarked images.
What a watermark is really for
A watermark does not prevent anyone from taking an image. Anything visible on a screen can be captured, and a determined person can crop or paint out a mark in minutes. What a watermark does is establish attribution and raise the cost of casual reuse — it makes an image obviously yours as it travels, so that when someone reposts it the credit travels with it.
That reframes the design question. You are not building a lock; you are signing your work. The mark needs to be legible enough to read wherever the image ends up, and unobtrusive enough that the image is still worth looking at.
Placement and opacity
The corner is the conventional placement and the easiest to remove — a crop takes it with it. Placing the mark closer to the centre, or over an area that matters compositionally, makes removal costly, at the price of intruding on the picture. Where you land between those two depends entirely on whether the image is a portfolio piece meant to be admired or a product photograph you expect to be scraped.
Opacity is the other dial. Around 30 to 50 percent generally reads clearly without dominating, though it depends on what is underneath: a pale mark disappears over a bright sky and a dark one vanishes in shadow. If your images vary, a mark with its own contrast — light text with a subtle dark edge, or vice versa — survives both. Size matters too: a watermark sized for a full-resolution photograph becomes unreadable once the image is scaled down for social media.
Marking a batch consistently
A watermark works as identification only if it is the same every time. Applying it as the last step, across a whole set at once, keeps position, size and opacity consistent — and consistency is what turns a mark into recognition rather than clutter.
Keep unwatermarked originals. You will eventually need a clean version for a print, a client or a licensing request, and there is no way back from a flattened watermark. Since the work happens in your browser, marking a hundred photographs costs nothing and uploads nothing, which also means unreleased work never sits on someone else's server waiting to be marked.
Good to know
Where you put a watermark is a trade-off between visibility and protection. A corner is the least intrusive and the standard choice for signing your own work; the centre is much harder to crop out, which is what you want if the point is discouraging reuse. Low opacity in the centre is usually the better compromise.
For a logo watermark, use a PNG with transparency — a logo on a white rectangle will sit on your photo as a white rectangle. Size is measured as a share of the image width, so the same settings scale proportionally across a batch of photos with different dimensions.
You can also drag the watermark anywhere on the preview instead of using the position presets, and the exact placement carries over to every image in the batch.
Frequently asked questions
Can I watermark many photos at once?
Yes. The same watermark settings are applied to every photo in the batch, scaled proportionally to each image, and there is no file limit.
Where should I place a watermark?
Corners are the least intrusive; the center is the hardest to crop out. For real protection use the center at low opacity — for signing your work, a corner is the usual choice.
Can I use a logo image instead of text?
Yes — switch the watermark type to “Logo” and upload an image (a PNG with transparency works best). You can adjust its size, position and opacity exactly like a text watermark.
Does watermarking reduce photo quality?
The photo is re-saved at high quality with the text drawn on top; outside the watermark area the image is visually identical.
Are my photos uploaded to be watermarked?
No. The mark is composited in your browser and the result downloaded directly, so unreleased work never leaves your device.
