Frequently asked questions
How much smaller is WebP than JPG?
Typically 20–35% at equivalent visual quality. Your exact saving is shown next to each converted file.
Does double lossy compression hurt quality?
Each lossy re-encode loses a little. Convert from the best original you have, and avoid repeatedly converting back and forth.
Should I keep my JPG originals?
Yes — keep originals as your archive and serve WebP copies on the web. This converter never modifies your source files.
About this tool
If your site serves JPG photos, re-encoding them as WebP is one of the cheapest performance wins available — same visual quality at meaningfully smaller sizes, better Core Web Vitals, less bandwidth. This converter does it without any upload: drop your JPGs, choose a quality, and download WebP files with the size delta shown per file. Both formats are lossy, so the sensible workflow is converting from your best-quality JPG original rather than one that has already been recompressed several times.
