Screenshot JPG
by phoupraw
Screenshot JPG converts each PNG screenshot a player takes into a JPG file, which takes less disk space than the original.
What it does
After the player takes a screenshot, the mod reads the saved PNG file, converts its pixels to JPG format and writes the JPG to the screenshots folder. The original PNG is then deleted, so only the smaller file remains. Players who capture many screenshots in a session can keep the folder smaller without changing how they take them.
If a converted JPG turns out larger than the PNG it came from, the mod ignores that screenshot and keeps the PNG as it is. The mod runs only on the client, so a server does not need it and players on multiplayer servers can use it alone. Screenshot JPG is a Fabric mod with files for 1.21 and 1.21.1, and the latest build is 0.1.1 for 1.21.1.
Screenshot JPG is released under the Mozilla Public License 2.0 and is not open source. It is installed on the player's side alone, so servers need nothing.
