Convert JPG to WebP Online — Smaller Files, Same Quality
Reduce image size by 25-35% by converting JPG to WebP.
About JPG to WebP
WebP is a modern image format that provides 25-35% smaller file sizes than JPG at equivalent visual quality. Converting your JPG images to WebP is one of the easiest ways to speed up your website, improve Core Web Vitals scores, or reduce storage and bandwidth usage. All major browsers — Chrome, Firefox, Safari, and Edge — now support WebP, making it a practical replacement for JPG in most web contexts. This tool performs the conversion entirely in your browser using the Canvas API, so no files are uploaded to any server and your images remain completely private. Adjust the quality slider to find the perfect balance between file size and visual fidelity for your specific use case. Web developers will appreciate the significant bandwidth savings, especially for image-heavy pages like portfolios, e-commerce catalogs, and media galleries. Bloggers and content creators can use this tool to optimize hero images and thumbnails before publishing. Batch processing support means you can convert an entire folder of JPGs to WebP in one go, saving time on large projects.
Questions
How much smaller will my WebP file be?
WebP files are typically 25-35% smaller than equivalent JPG files at the same visual quality. For a 1 MB JPG, you can expect a WebP around 650-750 KB.
Do all browsers support WebP?
Yes, all modern browsers — Chrome, Firefox, Safari, Edge, and Opera — support WebP. The only browsers that don't are Internet Explorer and very old versions of Safari (pre-14).
Should I use WebP for my website?
Absolutely. WebP is the recommended image format for the web. It offers the best balance of quality and file size, directly improving page load times and Core Web Vitals scores.
What quality setting should I use for WebP?
The default 85% keeps photographic detail intact. Drop to the Web ready preset (72%) when file size matters more, or pick Keep quality (94%) when the point is just the format change.
Will my photo come out sideways?
No. Phone cameras often store the image rotated and rely on an EXIF orientation tag, and the tool applies that rotation to the pixels while decoding — so the WebP displays upright everywhere, even though the EXIF tags themselves don't survive the re-encode.
Is my file uploaded to a server?
No. Transmute processes everything locally in your browser using JavaScript and WebAssembly. Your files never leave your device — there is no server, no upload, no cloud processing.
