What kind of image is it? Reducing the number of colors in a PNG is usually inferior to JPEG compression.
Some instance admins don’t even use the built-in pict-rs server so media cannot be uploaded natively at all.
Some only allow month-old accounts to post images up to 500 kiB.
Others leave the limits on the relatively high defaults: 10 MiB per file and up to 900 frames for soundless animation/video, which must be in WebM format and VP9 codec (or it will need to be reencoded, which usually fails). It’s easy to use ffmpeg or HandBrake to create low-bitrate 30-second HD videos that fit but the limits are not visible to users and even the defaults are nowhere to be found in Lemmy documentation, I had to read the source code.
