How to watermark many photos at once
Drop in all the photos you want to protect. Type your name, shop or social handle, or switch to Logo and pick your logo image. Choose one of the nine positions, or Tile to repeat the mark across the whole picture. The preview updates instantly; click any thumbnail to check another photo. Press Download to save one photo directly, or a ZIP when there are several.
Tips for a good watermark
- An opacity of 30–60% stays visible without spoiling the photo.
- A corner mark keeps the picture clean; a tiled, slightly rotated mark is much harder to crop or paint out.
- Turn on Shadow so white text stays readable on bright areas.
- Use a PNG logo with a transparent background so only the logo itself appears.
Will the quality drop?
Photos are saved at their full original size. Choose Same as original to keep each file's format, or JPG with quality around 90 for a good balance of sharpness and file size.
Are my images uploaded?
No. Everything happens inside your own browser, so your pictures never leave your device. It even keeps working if you go offline after the page loads.
