Yeah, but if the user can't say whether the user wants compressed data
or not, just tweaking the compression level is always going to be bad
for one use case (canvas) or the other (uploads).

Using PNG even for uncompressed data does sound better than BMP.
Alpha channel, 16bpp color, color management, etc. can all still
apply.
