95 is the maximum you should use - there's no perceptual difference between
95 and 100, but the size increase is huge.

Anyway, with most images you can go even lower - when exporting a JPEG,
tick the Preview checkbox, and play with the settings. You should always
enable both Progressive and Optimize, as those losslessly reduce the file
size, and switch the DCT mode to Floating point (slightly improves quality,
and usually reduces the file size). Try also different subsampling options
- depending on image content, you can get quite a size reduction while
having very little visual difference.
