When 500KB is the limit
Plenty of portals accept up to 500KB. This is a comfortable target for multi-page or lightly scanned PDFs that would lose too much detail at 100–200KB.
Quality kept, size honest
We compress toward 500KB, keep the file no larger than the original, and always report the real final size.
