How to convert JPG to WEBP
WebP produces images that are roughly 25-34% smaller than JPEG at equivalent visual quality. For a website with dozens of product photos or blog images, switching from JPEG to WebP can cut image payload significantly and improve page load times. Converting your existing JPEG library to WebP runs entirely in your browser using a WebAssembly-compiled encoder, so your photos never leave your device and there is no batch size limit from a server.
WebP lossy uses a different compression algorithm from JPEG (based on the VP8 video codec) that handles gradients and texture more efficiently. At a WebP quality setting of 80, the result typically looks identical to a JPEG at quality 90 while being about 30% smaller. The tradeoff is that WebP is not supported in Internet Explorer and some older applications. For a modern website, WebP is the practical default for photos; keep the JPEG originals for backward compatibility if needed.
Upload your JPEG file
Drop one or more .jpg or .jpeg files. Batch mode converts multiple images in sequence.
Set WebP quality
WebP quality 80 is a strong default. This usually produces a file visually equivalent to JPEG quality 90 but smaller.
Convert locally
The WebAssembly WebP encoder runs in your browser. No network request is made; your images stay on your device.
Download the WebP files
The output size is shown next to each converted file. The size reduction is typically visible immediately.
Frequently asked questions
How much smaller will my WebP be compared to JPEG?
On average 25-34% smaller at equivalent perceptual quality, based on Google's benchmark studies. The exact savings depend on image content.
Will the WebP look identical to the original JPEG?
At quality 80+, the difference is not visible on typical screens. Both are lossy formats, and the WebP codec handles certain textures differently from JPEG, but the overall appearance is equivalent.
Does WebP work in all browsers?
All modern browsers (Chrome, Firefox, Edge, Safari 14+) support WebP. Internet Explorer does not. For sites still supporting IE, serving JPEG as a fallback via the HTML picture element is the standard approach.
Can I convert WebP back to JPEG if needed?
Yes, but you will incur another round of lossy compression. Always keep the original JPEG for any use case where re-encoding might be needed.
Should I serve WebP or AVIF on my website?
AVIF achieves even better compression than WebP but takes longer to encode and has slightly less complete browser support. WebP is the safer default today; AVIF is worth adding as a higher-priority source in a picture element.
