The preflight checker measures a draft and a media file against every limit recorded for a platform, in the browser, without uploading anything. Opening it from this page preselects this platform.
How current this is
A platform can raise or lower a limit without announcing it. The value above is read for a freshly connected account with no elevated eligibility, and the date beside the source is the day a person last read that document.
