Hi HN,
I made a lightweight, header-only GIF decoder in C, inspired by stb-style libraries.
No dynamic allocation, portable, and optimized for embedded devices.
I made this to replace giflib for embedded and low-resource use cases.
It's:
header-only (drop-in),
zero-allocation (you provide the buffer),
faster LZW decoding (turbo mode),
compatible with C89 environments, etc.
Happy to get feedback or suggestions!

Listing code size numbers for arm-none-eabi-gnu might be good advertisement (compile/"size" output of a file using all the functions is enough, no need to figure out some target to link or have a main() for)

Good point — thanks! I’ll add a compiled code size example using `arm-none-eabi-gcc` and `size` to the README.
P.S. When I said size, I meant that it is very light and if you use it in a project, the binary itself will be smaller, and I used the ARM to test it.

What do you mean by this? Because the code I'm looking at does not appear to be C89.

You're right to question that — thanks for catching it. I aimed for C89-style compatibility (e.g., no `stdint.h`, minimal features), but I may have overlooked some modern extensions.

I see this phrase, complete with em-dash, dozens of times a day, every day.
Everyone does, I guess.

Haha fair point Guilty as charged — I guess I went full "HN polite mode" there.
But yeah, seriously appreciate the feedback — makes the project stronger.

I've seen some claim that it may imply the usage of LLMs.

Very nice project, interesting that there's a couple header-only projects on the front page today [0].
Thanks! Yeah, seems like it's header-only Thursday
I love the stb-style “drop-in and go” approach — it keeps things clean and easy to adopt, especially for low-level or embedded projects.
