I’m trying to make waterfalls spectrum data of very wide band to be shown on a webpage in browser remotely, so I’m trying to find the best way to compress data to be shown as much as possible to transfer it over the internet.
The format I’m looking at is just a 0-255 number for a pixel, and array of them represents each row of 1 tick of a spectral data, the larger the number – the lightest the pixel, or smth like this.
The piece I want to be shown momentarily is at least 1000×600 pixels, with additional uploads if needed while browsing history, but that I will do programmatically.

So as I understand there should be uint-8bit-only grayscale formats that do compression, I need it for both transferring speeds and taking place on a disk (since there’s a lot of data to be saved).
What are they?
Thx.

I tried to look in the internet but was overwhelmed by the information.
