Add Watermark to Image
Quick answer
Stamp a text mark or an uploaded logo across one photo or an entire batch, with control over position, opacity, size and rotation, all rendered locally before you ever hit download.
What the add watermark to image does
A watermark here can be typed text, such as a studio name or a copyright line, or an image you upload, such as a logo with a transparent background. Either one is placed using a nine-point grid (the four corners, the four edge midpoints, and dead center) so it lands in a predictable spot across a whole set of photos, and from there you control opacity, scale relative to the image, and rotation angle.
For a stronger deterrent than a single corner mark, the tile option repeats the watermark in a grid across the entire frame at low opacity, the way stock photography sites do, which is much harder to crop out than a single logo tucked in one corner. The batch mode applies the same settings to many files in one pass, which matters if you are watermarking an entire shoot of fifty or a hundred proofs rather than one image at a time.
It is worth being direct about what a visible watermark actually accomplishes. It discourages casual reuse, someone right-clicking and saving your photo to repost without credit, and it makes the source obvious at a glance. It is not a security or licensing mechanism: a single corner mark can be cropped off, and even a tiled mark can be painted or cloned out by anyone with enough patience and basic editing skill. Treat it as a low-friction speed bump for casual copying, not as protection against someone determined to remove it.
How to use it
Add your source images
Upload one photo, or several at once if you want the same watermark applied across a batch.
Choose text or a logo
Type a text watermark or upload a logo file with a transparent background.
Position and style it
Pick a spot on the nine-point grid, or enable tiling to repeat it across the frame, then set opacity, scale, and rotation.
Preview across the batch
Check a few different photos in the set, since a corner placement that looks right on one image can overlap the subject in another.
Export
Download the watermarked images individually or as a batch.
Your images never leave your device
A freelance photographer sharing low-resolution proofs before a client has paid the final invoice, or an illustrator posting a preview of a commissioned piece before the client has publicly announced it, both need the mark applied without handing the unwatermarked original to a third party in the process. Because the compositing happens on a canvas in your browser, the clean source file never has to be uploaded anywhere just to get a mark stamped onto a copy of it.

- Works offline after the first visit
- No account, no watermark, no limits
Format and quality tips
Low opacity plus tiling beats one bold corner mark
A single solid logo in a corner is trivial to crop off entirely, losing nothing but a few pixels at the edge. A repeating tile at 10 to 20 percent opacity is visually unobtrusive but sits across the whole subject, so removing it requires editing the entire image rather than just trimming a border.
Keep the source file separate from the export
Always keep your unwatermarked original somewhere safe. If you ever need a clean version for a print order or a licensing deal, you want the source, not a version you have to try to un-mark.
Frequently asked questions
Can a watermark be removed from my photo?
A determined person with editing skills can often remove or paint over a watermark, especially a light single-corner one; a tiled, semi-transparent watermark across the whole image is considerably more work to remove cleanly.
What image format should my logo watermark be?
Use a PNG with a transparent background so only the logo shape composites onto the photo, rather than a white or colored rectangle sitting on top of it.
Can I watermark many photos at once?
Yes, batch mode applies the same text or logo, position, opacity and scale settings across every file you add in one pass.
What opacity should I use for a watermark?
Somewhere around 40 to 60 percent for a single visible corner mark keeps it legible without covering the subject; tiled watermarks usually look better much lower, around 10 to 20 percent.
Does a watermark protect my copyright?
A watermark is a deterrent and a visible credit, not a legal protection mechanism by itself; your copyright exists independently of whether the image is marked, but marking it does make casual reuse without credit less likely.
Can I rotate the watermark diagonally across the image?
Yes, the rotation control accepts any angle, which is common for a diagonal proof stamp across the full frame.
