How It Works (Technical Specs)
fbutube compresses images locally using browser technology. Depending on the file type and settings, compression can be lossy (smaller files with minimal visual change) or closer to lossless (especially for some PNG cases). The process may also remove unnecessary metadata to help reduce file size.
- Lossy vs. lossless compression
- EXIF / metadata optimization
- Modern format options like WebP conversion (available in our converter tools)
- Quality-focused encoding approaches inspired by common standards like MozJPEG and OptiPNG
