Why convert JPEG to WebP?
WebP uses VP8 block prediction and arithmetic entropy coding (rather than JPEG's older 1992 Huffman coding), producing cleaner gradients and fewer blocky artifacts at low bitrates.
Private by design: zero uploads
Instant client-side Canvas/WASM encoding—no file size limits or server queues.
Frequently asked questions
What quality slider value is best for JPG to WebP?
A WebP quality setting between 80 and 88 generally matches the visual sharpness of a 90% JPEG at a noticeably smaller file size.
