Watermark image

Add text, a logo, or a tiled mark to one image or a whole batch.

Protect photos or credit your work with either styled text or a logo image. Both modes support precise placement, opacity, rotation, single marks, tiled patterns, and batches of up to 20 images.

Watermarking runs locally in your browser, so client photos and unreleased work never leave your device.

JPG · PNG · WebP · up to 20 files · 50 MB each

How it works

  1. Add images. Drop, paste, or choose up to 20 JPG, PNG, or WebP files.
  2. Choose text or logo. Type and style a text mark, or add a logo image, then set placement, opacity, rotation, and an optional tiled pattern.
  3. Apply and download. Watermark the whole batch in one pass and download images individually or as a ZIP.

Frequently asked questions

Are my photos uploaded when I watermark them?

No. Everything runs locally in your browser using the Canvas and File APIs. Your files are never uploaded to a server, and nothing is stored after you close the page.

Can I watermark many photos at once?

Yes. Up to 20 images can be watermarked in one batch with identical settings, then downloaded together as a ZIP.

Can I control the watermark's transparency?

Yes. Opacity is fully adjustable, so the watermark can be a subtle credit or a strong deterrent.

Does a text watermark reduce image quality?

The watermark is composited onto the image and the file is re-encoded at high quality; outside the watermark itself, any difference is visually negligible.

Should I use text or a logo watermark?

Text is fastest for names, copyright notices, and URLs. A transparent PNG logo is better when you need a consistent visual brand mark.

Can I repeat a watermark across the image?

Yes. Both text and logo modes support tiled patterns for broader coverage.
