Watermark the image formats you already use

Use JPG, PNG, WebP, AVIF, GIF, or BMP files up to 50 MB. Export as JPG, PNG, or WebP and choose a practical quality for sharing, publishing, or archiving.

JPG / JPEG

Best for photos and everyday sharing. Transparency becomes white.

PNG

Best for screenshots, logos, and transparent assets.

WebP

Smaller files for websites, blogs, and product pages.

AVIF / GIF / BMP

Accepted as input. Animated GIFs are exported as the first frame.

Your images stay on your device

The page uses the browser File API, Image, and Canvas APIs to read, compose, and export locally. Originals are not sent to MediaKit servers or stored in the cloud. Temporary object URLs are released when you clear the task or close the page.

FAQ

Frequently asked questions

Will my image be uploaded?

No. The browser reads, composes, and exports your image locally with the File API and Canvas.

Can I add my own logo?

Yes. Switch to Logo, then choose a PNG, SVG, JPG, or WebP image. Transparent PNG or SVG files work best.

Why does my JPG have a white background?

JPG does not support transparency, so transparent pixels are exported with a white background. Choose PNG or WebP when transparency matters.

Can I watermark multiple images?

This page is designed for quick single-image editing. A batch workflow can be added as a separate tool because multiple large images use more browser memory.
