1. Add your images

Or drop JPG, PNG or WebP files here. Up to 30 images, 20 MiB each, 80 MiB total and 16 million pixels per image. Animation is not preserved.

Choose images to begin.

2. Design your watermark

Text size, logo width and margins scale with each image. Long or rotated marks shrink to fit. Metadata is not copied; JPG adds the chosen background to transparency.

Using Batch Image Watermark

Add a consistent text signature or logo to a group of images without uploading them.

  1. Choose or drop up to 30 JPG, PNG or WebP images. Each image can be up to 20 MiB and 16 million pixels; total source size is limited to 80 MiB.
  2. Choose text or a logo, then adjust relative size, opacity, margin, position and rotation. Check each image using the preview selector and original-image toggle.
  3. Choose PNG, JPG or WebP and create the downloads. Save individual images or the ZIP; original files are unchanged.

Example

Use bottom-right text at 5% size, 3% margin and 65% opacity.
A 1,000-pixel shorter edge uses a 50-pixel text size and a 30-pixel margin; a 2,000-pixel edge uses 100 and 60 pixels. Long marks shrink to fit.

Questions & answers

Does a watermark stop people copying an image?

No. A watermark communicates attribution and may discourage reuse, but it does not prevent copying or removal. Repeated marks cover more of the picture and can reduce readability.

Do images keep their original dimensions?

Yes. Export preserves the decoded image dimensions. Camera orientation is applied by the browser; metadata such as EXIF is not copied.

Can I use a transparent logo?

Yes. Choose a transparent PNG logo. PNG and WebP output preserve image transparency; JPG fills transparent areas with your chosen background.

Is a logo the same size on every photo?

Its width is a percentage of each image’s shorter edge. Text size and margins are relative too, so mixed image sizes get consistent proportions.

Can I watermark GIFs or animated images?

This tool exports still images and does not preserve animation. Use GIF Watermark for GIF animations.

Are my files uploaded or saved?

No. Your images and logo are processed in this browser session. Clear or close the tool to release them.
