Government portals, job applications and visa systems often demand uploads under 100–200 KB. Whether a PDF can get that small depends on what's in it: a 2-page text document compresses far below 100 KB, while a 30-page photo scan physically can't without becoming unreadable.
Use “Strong” mode for maximum reduction. If you're still over the limit, split the document first and compress only the pages the portal actually needs. That combination solves most 100 KB requirements.

2Choose “Strong”, the smallest-size preset.
3Check the live size estimate, then download.
4Still too big? Use Split PDF to keep only the required pages, then compress again.
