How to compress and decompress the bin file for OTA

[GaneshPodPoint]

Hi there,
I have seen in internet that some people are compressing the bin file for OTA.
Could you tell us that what library should i use to compress and decompress the bin file? and i have seen that it is done in esptool.py while flashing the bin file via serial port.

Thanks
Ganesh

Thanks for your support with no answer.

What was the solution?

Ive been curious about this too...it would be nice to not require 5 minutes just to OTA-download a bin to SPIFFS...
