The Cheapest Win in Page Weight
WebP was designed as a direct replacement for JPEG and reaches roughly the same perceived quality at 25-35% less weight. Unlike AVIF it encodes almost instantly and has been supported by every major browser for years, which makes it the low-risk step for a site still serving JPEG. If you want to go further still, our JPG to AVIF converter trades encode time for another sizeable reduction.
Nothing Leaves Your Device
This tool runs entirely inside your browser. Your image is never uploaded to a server, which means it is also never queued, logged, or retained — and the tool keeps working with your network disconnected.
Key Features
- Quality slider from 1 to 100, defaulting to 80 — the point where WebP stays visually transparent for most photos
- Encodes in milliseconds, unlike AVIF which trades speed for size
- Batch convert and download everything as a single ZIP
- Runs in your browser, so large batches cost you no upload time
