Placement guide
Where a watermark earns its keep
A watermark on proofs tells clients which photos are still yours. The goal is to be legible without wrecking the frame, so placement and opacity matter more than size.
- Corners survive crops better than centers, but a tiled pattern deters re-use the most.
- 55 to 70 percent opacity reads clearly without burying the image.
- For selection proofs, size the mark at roughly 20 percent of the long edge.
- Keep one consistent mark across a gallery so screenshots stay traceable.
Frequently asked
Before you stamp
Does watermarking reduce photo quality?
The pixels under the mark change, the rest of the photo does not. This tool re-encodes at high quality, and you control the output format. For PNG input the export stays lossless.
Where should I place a watermark?
Corners survive social crops best; a tiled pattern across the frame is the strongest deterrent. For client proofs, bottom right at moderate opacity is the common choice, and the preview lets you test placement on your own photos.
Is it safe to watermark photos online?
Here, yes: this tool runs entirely in your browser. Your photos are never uploaded, there is no server processing, and closing the tab leaves nothing behind.
Can I watermark multiple photos at once?
Yes. Drop up to 50 photos, style the mark once, and export the whole batch as a ZIP. Each photo is processed at full resolution, one at a time, on your device.
Does the tool strip my photo metadata?
Yes. Re-encoding removes EXIF data, including GPS location, which is good for client privacy. Be aware it also removes embedded copyright fields, so keep your originals.
