 - Single binary: no external tools required
 - Auto-detects input codec and infers output from the file extension
-- Supports AVIF, BMP, Farbfeld, GIF, ICO, JPEG, JPEG XL, PCX, PNG, PNM (PBM/PGM/PPM/PAM), PSD (decode-only), QOI, SVG (decode-only), TGA, TIFF, WebP and XBM

 - Lossy or lossless output with configurable quality
 - Thumbnail generation via Lanczos3 resampling
 - Per-codec flags for fine-grained control (see `ffwebp --help`)
