Compress PDF to 90KB
The 90KB target is mostly a strategy: land safely under a 100KB cap with margin for portals that measure strictly — while keeping effectively 100KB-tier quality. We compress toward your target at the best quality that fits, never make the file larger than the original, and always show the real final size — very image-heavy files may land slightly above tight targets.

The margin play
Portals occasionally count size differently — bytes vs. kilobytes, before vs. after their own re-encoding. Targeting 90KB for a 100KB field removes the resubmission lottery: your file clears the gate every time, and the quality cost of those 10KB is minimal.
Same honest engine
Everything else works as always: best quality that fits, never larger than the original, the true size displayed before you upload anywhere.
