Select one or many JPG/JPEG images — they are converted to WebP on your device, never uploaded.
JPEG has been the web's photo format for 30 years — WebP does the same job in 25–34% fewer bytes. Convert your JPGs in bulk, right in your browser, for free.
We believe in privacy first. By leveraging HTML5 Canvas and native browser APIs, your images are converted on your device. Zero files are uploaded to our servers, ensuring your data remains yours.
Stop wasting time converting files one by one. Drag and drop dozens of images into the work area and convert them all at once with incredible speed.
Tweak the quality slider to find the perfect balance between visual fidelity and file size reduction. Works perfectly for both WebP and JPG outputs.
Need WebP? Convert JPG or PNG. Need JPG? Convert your WebP format images quickly. Flexibility to shift between next-gen and legacy formats in seconds.
JPG (JPEG) is the classic format for photographs, but its compression is showing its age. WebP, developed by Google, encodes the same photographic content 25–34% smaller at equivalent visual quality — which directly translates into faster page loads, better Core Web Vitals scores, and lower bandwidth costs.
Every modern browser supports WebP, so for websites, shops, and blogs there is little reason to keep serving JPGs. This converter re-encodes your JPGs to WebP entirely on your device using the browser's own codecs — your photos are never uploaded anywhere, and the tool even works offline.
Use the quality slider to pick your trade-off: 80% is an excellent default for web photos, while 90%+ is nearly indistinguishable from the original. You can convert dozens of images in one batch.
Drag and drop one or many JPG/JPEG files into the dropzone — batch conversion is supported.
The output format is already set to WebP. Switch to PNG instead if you need lossless output.
80% is a great default for web photos; raise it toward 100% for archival-grade fidelity.
Click 'Convert & Download All' and save the smaller WebP files to your device.
For photographic content, WebP is typically 25–34% smaller than JPEG at equivalent visual quality. Actual savings depend on the image and the quality setting you choose.
Both JPG and WebP are lossy formats, so re-encoding involves a generation of compression. At 80–90% quality the difference is invisible in practice; use higher settings if you're archiving.
No. The conversion runs entirely in your browser using the Canvas API — disconnect from the internet and it still works. Nothing you convert ever leaves your device.
All modern browsers (Chrome, Firefox, Safari, Edge) support WebP. Some older desktop software doesn't — if you need to go back, use our WebP to JPG converter.
