Bulk watermark
Tile a repeating watermark across every photo in a batch.
How to use Bulk watermark
- Drop the whole batch of images onto the upload area.
- Type your watermark text and pick its colour, or upload a logo instead.
- Adjust the size, angle, gap and opacity sliders to get the tiled pattern you want.
- Choose an output format under Save as and click Apply to batch.
- Click Download all to save every watermarked image as a zip.
A single watermark in one corner is easy to crop out — this instead repeats the mark across the whole photo on a rotated grid, the same technique stock photo sites use, so there's no clean area left to crop around it.
Angle, spacing and opacity are all adjustable — a steep diagonal at low opacity reads as a subtle, professional overlay rather than something that competes with the photo underneath. The live preview updates as you adjust each setting, so you can dial it in before applying it to the whole batch.
Everything runs in your browser — nothing is uploaded, so there's no limit on how many photos you protect at once. Set it up on the first photo, apply it to the batch, and download the results together as a ZIP.
Questions
How is this different from Add watermark?
Add watermark places a single mark once, in one of nine positions — good for a subtle credit line. This one repeats the mark across the entire photo on a diagonal grid, which is much harder to crop or clone-stamp away — the right choice when you're actually trying to deter someone from lifting your photos.
What angle and opacity should I use?
A diagonal around -30° is the conventional choice — it reads clearly without following the photo's natural horizontal or vertical lines. Keep opacity low (20-40%) if you still want the photo itself to be the focus; push it higher for a more aggressive, unmistakable mark.
Can I use my logo instead of text?
Yes — switch to Logo and upload an image, ideally a PNG with a transparent background so the tiled copies don't show as solid boxes.
Can I apply the same watermark to a whole folder of photos?
Yes — that's the point of this tool. Drop in the whole batch, set the watermark up once using the preview, and apply it to everything together.
Are my photos uploaded anywhere?
No. The watermark is drawn entirely in your browser — the files never leave your device.
