Convert BMP to JPG in your browser
BMP is used by Windows since the 1980s, stores pixels uncompressed, very large since pixels are uncompressed (a 4K BMP can exceed 30 MB). JPEG is the more practical choice when universal: every browser, OS, design tool and ancient CMS opens JPG without effort. Filzy converts BMP to JPG fully in your browser using Rust 'image' crate for decoding and optimised JPEG encoder in Rust for encoding. The original file never leaves your device, no upload, no tracking, no daily cap. You can drop a single file or batch dozens at once and download the result as a ZIP.
Files stay on your device
Your BMP files are decoded inside a Web Worker via WebAssembly. Nothing reaches a server, nothing is logged, no temporary copy is kept anywhere.
Quality preserved by default
Filzy decodes the BMP pixels, then re-encodes them with optimised JPEG encoder in Rust at high quality. EXIF metadata is preserved when the target format supports it.
Batch entire folders
Drop dozens of BMP files at once. Filzy converts them in parallel using your CPU cores and packages everything as a single ZIP archive.
