can we use it for 7z compression instead of gzip

No, as web browsers only support gzip and Brotli compression. The 7Z format uses LZMA2 compression.

Thank you, but the gzip size i getting larger for my .wasm it nears 38MB I want it to get it around 18-20MB
for in work and the original size of my .wasm is 131MB can you help to reduce it?

No, as web browsers only support gzip and Brotli compression. The 7Z format uses LZMA2 compression.

But the compression of 7z is getting less than the gzip size how to use it for loading and preloading the .wasm and .pck with a .7z extension can help with this, please?

@learnyTown

Sir, please give me a reply on how to use it
and how to compress the file up to 20 MB from 131MB for Gzip file compression.

Is there any one to solve my problem?

About `incorrect header check error:
I solved this error and upload my game at CrazyGames QATool and works ok:
1- Comment or remove this lines:

// if (file.endsWith(".wasm") || file.endsWith(".pck")) {
//		file += ".gz"
//	}

2- Rename Gzipped .wasm and .pck files and remove .gz extension.
And now my game runs ok on both local and remote servers.
