Emotes get unnecessarily compressed

[saucylegs]

Often when a GIF emote is added, the bot will compress it even if it is already less than 256kB. The result is the bot adds an emote that is much blurrier than it would be if it was added manually.

@saucylegs Would you mind sending an emote that's smaller than 256 kB but got compressed anyway?

Now that I test this again, it appears that it only happens if you use an existing emote in the command, e.g. em/add test2 :test1:

That compressed this: https://cdn.discordapp.com/emojis/764339726664204350.gif?v=1

Discord imposes a limit of 256 KiB on emotes, yet that emote is in fact 294,544 bytes large. EM's strategy for compressing emotes is to just halve their size repeatedly until they're less than 256 KiB. So how did that emote get to be larger than the size limit in the first place? The most likely explanation is that the original image for that emote was larger than the size limit, so Discord itself tried to compress the emote, but it got larger when compressed or resized. Yes, GIF is really this horrible.

As for workarounds, you can try using gifsicle's optimization features before uploading. I'll leave this issue open as a reminder to try gifsicle within EM.
