Could you build this?
No Designing and implementing a novel lossy image compression format using Discrete Cosine Transforms requires specialized signal processing, binary encoding, and codec engineering skills.
What it would actually take: Building a custom image codec requires deep knowledge of digital signal processing (2D DCTs, quantization matrices, chrominance subsampling) and bit-level serialization. The stack typically involves writing the core encoder and decoder in C, Rust, or Zig for performance and safety, followed by compiling to WebAssembly for browser support. Tuning quality versus byte constraints requires extensive empirical benchmarking against existing algorithms like JPEG, BlurHash, and ThumbHash.
