Any file up to 500 MB. Drop several files and they come back as one ZIP. Many image, audio and video conversions run in your browser; anything else is uploaded and removed within the hour.
Convert JPEG raster images to WEBP format quickly and securely using ConvertX. This tool is essential for web developers and content creators optimizing site performance.
Both JPEG and WEBP are raster image formats, but WEBP is a modern standard developed by Google designed specifically for the web. When you convert a JPEG to WEBP, the underlying pixel data is re-encoded into the WEBP container structure. Because both formats rely on lossy compression, translating from one to the other involves decoding the original JPEG blocks and re-compressing them into WEBP blocks.
Since both formats use lossy compression algorithms, this conversion involves re-compression. Repeated lossy compression can cause a slight degradation in visual quality, so you should avoid multiple consecutive conversions between these formats.
We built this project so anyone can convert files without paywalls, accounts, or hidden limits. Here is what that promise means in practice.
Every converter on ConvertX is free to use: no trials, no premium tiers, and no credit packs. We will never put core conversion features behind a subscription. Whether you convert one photo or a hundred files a week, the price stays zero.
Many image, audio, and video conversions run entirely in your browser. Your files never leave your device for those jobs. When server processing is required for documents or specialized formats, uploads are handled securely and removed automatically — typically within one hour.
A quick guide to strengths and trade-offs of popular formats — so you pick the right one before converting.
