FAQ
Keep PNG format?
True lossless PNG optimization needs specialized codecs. Here, WebP/JPEG gives predictable size wins.
Is transparency kept?
Saving as WebP keeps transparency. JPEG fills transparent areas with white.
Are my files stored on a server?
No. Images are processed with Canvas in this browser; there is no upload request at all. Closing the tab clears memory.
Can I process several images at once?
One image at a time for now, so you can check the preview and final size for each file.
