The facts
Each one read from Jpegli's own pages, with the date it was checked.
What it does
- Adaptive quantization
- Jpegli uses adaptive dead-zone quantization with higher zero-coefficient thresholds in noisy image regions than in smoother regions.checked 12 Oct 2026
- API access
- Yeschecked 24 Sep 2026
- Build outputs
- Building the project produces cjpegli and djpegli binaries and a libjpeg.so.62.3.0 shared library that can replace a system library with the same name.checked 11 Oct 2026
- Build targets
- The build documentation describes cross-compiling for other architectures and mentions additional environment setup for Windows targets.checked 11 Oct 2026
- Command line and library
- Building the project produces cjpegli and djpegli binaries and a libjpeg shared library intended as a drop-in replacement for the system library of the same name.checked 12 Oct 2026
- Compatibility
- Google describes Jpegli as a fully interoperable encoder and decoder that complies with the original JPEG standard and its conventional 8-bit format.checked 12 Oct 2026
- Compression
- Google says Jpegli can compress high quality images 35% more than traditional JPEG codecs.checked 12 Oct 2026

- Encoder inputs
- The encoder supports 16-bit unsigned and 32-bit floating point input buffers.checked 12 Oct 2026
- Floating-point processing
- Color-space conversion, chroma subsampling, and DCT use floating-point precision before final quantization.checked 11 Oct 2026
- Integration
- The library is designed as a drop-in replacement compatible with the libjpeg62 API and ABI.checked 11 Oct 2026
- Intended users
- The README identifies the Git guide as being for developers and provides build and testing instructions for the project.checked 11 Oct 2026
