FAQ
Image compression questions
Will compression upload images to the server?
No. This compressor uses browser Canvas APIs, so selected files stay on your device.
Which output format should I choose?
Choose WebP for most website delivery files. Choose JPG for systems that do not accept WebP or when you need a simple photo fallback.
Why can a compressed file become larger?
Small icons, already optimized files, or PNG graphics with flat colors may not shrink after canvas export. Compare the result before replacing originals.
