/ About the tool
Why convert images to AVIF or WebP?
AVIF and WebP usually produce much smaller files at quality close to JPG/PNG.
Smaller payloads help LCP, transfer cost and — at scale — CO₂e estimates. This is not an emissions measurement.
Conversion is local (canvas). Images never leave the browser.
/ Formats
Which format to pick?
WebP
Web Picture Format
Wide support — solid size/compatibility trade-off.
JPG
JPEG
Legacy standard without transparency — often a fallback.
PNG
PNG
Lossless with transparency. WebP/AVIF usually cuts transfer a lot.
/ FAQ
Frequently asked questions
Yes (like JPG). Quality ~80 is a common start. Use higher quality for logos.
Decode yes in newer versions. Encode depends on the browser — fall back to WebP.
Canvas encoding usually drops metadata. Treat this as strip.
