JPG to WebP

A JPG to WebP converter re-encodes a JPEG photo into Google's WebP format, which usually stores the same picture in a noticeably smaller file. WebP supports both lossy and lossless compression, and for typical photographs its lossy mode reaches comparable visual quality to JPEG at roughly 25-35% fewer bytes. This tool runs entirely in your browser: it decodes each JPG with the Canvas API and re-encodes it as WebP, so your photos are never uploaded to a server. One detail worth understanding is that JPEG is already a lossy format, so converting JPG to WebP is a transcode, not a clean re-compression. The original JPEG compression artifacts are baked in and carried over, and the WebP step adds a second, usually mild, lossy pass on top. For that reason WebP shines most when you start from a high-quality source rather than an already heavily compressed JPG. WebP is supported in every current major browser, including Chrome, Edge, Firefox, and Safari, which makes it a safe default for websites where page weight and Core Web Vitals matter. It is a poor choice, however, for email attachments, print shops, or older software that still expects JPEG. Batch conversion lets you drop a whole folder of photos at once and download them together, which is handy when preparing a gallery, a product catalog, or blog images. Because everything happens locally, the tool is fast, works offline after the page loads, and keeps private photos private.
