Drag in one or more JPEGs, pick your preferred quality, and compare results instantly with an interactive
slider. Everything runs on-device: we use Canvas/WebCodecs when available and fall back to
@squoosh/lib in a dedicated worker for consistent, private conversions.
Drop JPEGs into the uploader or browse your device. We support files up to 20 MB each.
Choose your WebP quality, enable auto-downloads, and queue as many files as you like.
Use the slider preview to inspect results, then download individually or automatically.
WebP delivers smaller file sizes than JPEG at the same visual quality, which means faster loading times and better Core Web Vitals scores. Use this converter to upgrade product photos, blog graphics, and hero images without leaving the browser.
Batch conversions, adjustable quality controls, and interactive previews are available today. Next up: AVIF support and additional compression recipes powered by the same worker + WebAssembly architecture that runs in this release.
