What types of watermarks can I add?

Text watermarks with custom font size, color, opacity, and position. Image watermarks may be added in a future update.

Where can I position the watermark?

Five positions are available: top-left, top-right, center, bottom-left, and bottom-right.

Yes. Use the opacity slider to set the transparency of the watermark text from 0% (invisible) to 100% (fully opaque).

Yes. The watermark overlays every frame so it appears consistently throughout the animation.

Once burned into the GIF, the watermark cannot be removed without access to the original un-watermarked file. Always keep a copy of the original.

The tool uses the system default sans-serif font for maximum compatibility. Custom font support may be added in the future.

A shadow effect is automatically applied to improve readability on both light and dark backgrounds.

Currently one watermark is applied per session. Apply the tool multiple times to add sequential layers.

Re-encoding is required, which reduces the palette to 256 colors. The quality impact is typically minimal for text overlays.

No. A new watermarked GIF is created in your browser. Your original file is not modified.
