EzGz - An easy to use single header no dependency library for decompression of .gz archives written in modern C++ (probably faster than zlib)
You may be right about this. I'm actually mainly concerned about including as just including it can increase binary size substantially, see e.g. https://github.com/nholthaus/units/issues/32

I personally use, and recommend, the units library by Holthaus: https://github.com/nholthaus/units

Hello, PNG
CRC is a table and 5 lines of code. That's trivial.
>zlib is 23k lines
It's not needed to make a PNG reader/writer. zlib is massive overkill for only making a PNG reader or writer. Here's a tiny deflate/inflate code [2] under 1k lines (and could be much smaller if needed).
stb[0] has single headers of ~7k lines total including all of the formats PNG, JPG, BMP,. PSD, GIF, HDR, and PIC. Here's [1] a 3k lines single file PNG version with tons if #ifdefs for all sorts of platforms. Removing those and I'd not be surprised if you could not do it in ~1k lines (which I'd consider quite simple compared to most of todays' media formats).
>Of course they're not common formats so you're stuck with complex formats like PNG
BMP is super common and easy to use anywhere.
I use flat image files all the time for quick and dirty stuff. They quickly saturate disk speeds and networking speeds (say recording a few decent speed cameras), and I've found PNG compression to alleviate those saturate CPU speeds (some libs are super slow, some are vastly faster). I've many times made custom compression formats to balance these for high performance tools when neither things like BMPs or things like PNG would suffice.

EzGz - An easy to use single header no dependency library for decompression of .gz archives written in modern C++ (probably faster than zlib)
Right now I'm using a C library (https://github.com/jibsen/tinf) due to size constraints. Adding a few hundred kB is prohibitive in that space.
What are some alternatives?

Stm32-FatFs-Gzip - This project offers a simplified compressor that produces Gzip-compatible output with small resources for microcontrollers and edge computers. He uses the very basic LZ77 compression algorithm and static Deflate Huffman tree encoding to compress / decompress data into Gzip files.
