What does this tool solve?
Adjust multiple images to JPG, PNG, or WebP in the browser. Results show the before and after file sizes plus the signed size change, while JPEG and WebP quality can be tuned before downloading or passing the results to another image tool.

The browser decodes each image, draws it to a Canvas, and exports the selected MIME type as a local Blob.
Changing the output format or quality automatically regenerates all current results without uploading the source files; More actions passes the current results to another image tool.
What are the edge cases and limits?
- JPG, PNG, and WebP output is supported where the browser reports the requested MIME type.
- JPEG exports use a white background for transparent pixels and may remove EXIF metadata.
- PNG output is lossless and does not use the quality slider.
