Image Format Saver от piggystudio

Image Format Saver lets you save images from the right-click menu as PNG, JPG, WebP, or in the original image format.

All conversion happens locally in your browser. Images are not uploaded to a server, and the extension does not include tracking, ads, or affiliate injection.

Features:
- Save image in original format
- Save image as PNG
- Save image as JPG
- Save image as WebP
- Adjust JPEG and WebP quality
- Choose the background color used when converting transparent images to JPG

Notes:
- Animated GIF and animated WebP may become a static image when converted. Use original format to keep animation.
- Some protected, login-only, anti-hotlink, or blob URL images may not be convertible. In those cases, the extension will try to save the original image.
