Re-encode WebP with optimised parameters. Strip bloated metadata. Process entirely in your browser - no upload to any server.
Drag & drop or click to browse (WEBP)
WebP was designed to be small - but even WebP files can carry unnecessary metadata, suboptimal encoding parameters, and embedded ICC colour profiles that bloat file size significantly.
FastCompressor re-encodes WebP files using VP8/VP8L at optimised bitrates, strips non-essential metadata, and gives you the lightest possible file without a visible quality change.
Google's Squoosh and most converters produce WebP files at default parameters.
Those defaults aren't always optimal.
FastCompressor applies content-aware bitrate selection - sharpening where needed, compressing where not.
A WebP exported from Adobe Lightroom or Photoshop often contains 30-80KB of embedded EXIF, ICC colour profiles, and XMP data.
FastCompressor strips what's unnecessary while preserving what you need.
Every WebP compressor that runs 'in the browser' but actually uploads - iLoveIMG, Convertio, CloudConvert - sends your files to their servers.
FastCompressor processes WebP files entirely locally.
Frontend developers don't compress one WebP at a time.
They compress entire /assets/ folders.
FastCompressor's folder watch mode automatically compresses new WebP files as you export them.
Built for professionals who need speed, privacy, and quality.
Learn how it works
WebP is efficient. Uncompressed WebP isn't.
When Google introduced WebP, it promised 25-35% smaller files than JPEG at equivalent quality. That's true - when WebP is compressed correctly. The problem is that most tools export WebP at maximum quality by default. Figma, Photoshop, and export pipelines all do this. You get a .webp file that's already smaller than a JPG - but still far larger than an optimally compressed WebP.
FastCompressor's WebP compression analyses both the lossy and lossless components of each WebP file and re-encodes with content-aware settings. The result: a WebP file that is typically 30-50% smaller than the original exported version, with no visible quality difference at standard viewing sizes.
For web developers: WebP is the dominant format for web delivery in 2026, with 97% browser support. But the compression quality of your WebP files matters as much as the format itself. A poorly compressed WebP is larger than a well-compressed JPG.
For WordPress users: If you're using a plugin to auto-convert images to WebP, the output quality setting matters. Default is usually 80 - but many images can go to 70-75 with no visible change. FastCompressor's desktop app lets you set per-folder quality targets for complete control.
