Turn JPG photos into WebP files in your browser — the same picture at roughly two-thirds of the size, which is why most sites serve WebP today. Nothing is uploaded: your photos stay on your device. Free, no sign-up, no watermark, up to 20 files at a time.
Drop JPG files here to convert to WebP
JPG in, WebP out — up to 20 files, 50.00 MB each. Nothing is uploaded.
WebP uses a newer compression method than JPG and reaches the same visual quality in roughly two-thirds of the bytes. On a photo-heavy page that difference shows up directly in load time: a gallery of twenty 200 KB JPGs becomes about twenty 140 KB WebP files, which is 1.2 MB less to transfer.
The conversion happens entirely on your device. Your browser decodes the JPG, paints it on a canvas and encodes the result as WebP — no round trip to a server, which also means no upload time and no waiting in a queue.
Keep the JPG whenever the file has to leave the web: sending it to a print shop, attaching it to a form that only accepts .jpg, or opening it in an older desktop editor. WebP wins on size; JPG still wins on ubiquity.
Once. WebP re-encodes the picture, and because JPG is already an approximation the second pass adds a little loss. At the default 90% it is hard to see; below that, softness starts to show around edges and text.
Yes. WebP is supported by Chrome, Edge, Firefox, Safari and Opera, and any browser released in the last decade will display it. The exceptions are old desktop software — a photo editor from before 2018 may refuse to open WebP, so keep the JPG if that is where the file is going.
Usually 25–35% at the same visual quality. The saving is largest on photographs and smallest on flat-colour graphics or images that were already heavily compressed — a JPG saved at quality 60 will not shrink much further.
Yes. The pixel dimensions are kept identical — a 4000×3000 photo stays 4000×3000. Only the encoding changes, so you never lose detail by resizing.
Yes — up to 20 files per run, each up to 50 MB. Everything runs on your own device, one file at a time, with no upload and no queue.
No. Decoding and encoding both happen inside your browser with the Canvas API and a Web Worker, so your photos never leave your device.
Shrink photos to an exact target size (1 MB, 500 KB, 200 KB, 100 KB, 50 KB, 20 KB) without uploading them. Runs 100% in your browser — private, free, no sign-up, no watermark.
Convert WebP to JPG without uploading anything. Runs 100% in your browser — free, private, no sign-up, no watermark, and the original pixel dimensions are kept.
Convert SVG to PNG in your browser without uploading. Reads the SVG’s own width, height or viewBox so the PNG comes out at the right size, with transparency preserved.
Convert AVIF to JPG without uploading. Runs 100% in your browser — free, private, no sign-up, and the original pixel dimensions are preserved.
