- Always verify converted graphics in your target application before archiving original files.
Frequently asked questions
Frequently asked questions
Because JPEG does not support transparency, transparent areas are filled with a solid background color during conversion.
WebP provides superior lossy and lossless compression compared to JPEG and PNG, helping websites load faster.
No. All format conversion uses HTML5 Canvas `toBlob` encoding directly in your web browser.
AVIF decoding and encoding depend on your browser version. If AVIF is unsupported, the tool suggests WebP as a compatible alternative.
