Wuffs is a memory-safe programming language plus a standard library for safely parsing, decoding and encoding untrusted file formats such as images, audio, video, fonts and compressed archives. It compiles to fast C code that can be used in C/C++ projects without the Wuffs toolchain, with buffer overflow, integer overflow and null dereference checks proven at compile time.

Use cases

• decode png gif jpeg images safely in C or C++
• parse untrusted file formats without memory safety bugs
• fast deflate and bzip2 decompression alternative to zlib
• embed safe codecs in browsers or operating systems
• write memory-safe decoders that run as fast as C
• decompress compressed archives without buffer overflows

When to choose

• you need C-speed codecs with memory safety guarantees
• you are parsing untrusted input in a large C/C++ codebase like a browser
• performance of zlib, libpng or giflib is a bottleneck

When to avoid

• you need a general purpose programming language for applications
• you want quick development - Wuffs requires explicit safety annotations and is slower to write
• you need formats not covered by its standard library
