Compress PDF to 100 KB, 200 KB or 500 KB
Type the size the portal wants and FABX re-renders each page at decreasing resolution until the PDF fits. Best for scanned documents (Aadhaar, marksheets, certificates, invoices). Pages are stored as images, so text becomes non-selectable — fine for uploads, not for editing.
How to compress pdf to 100 kb, 200 kb or 500 kb
- Choose the PDF.

Questions
Why is my text no longer selectable?
To reach small sizes reliably, each page is converted to a compressed image. For text-heavy PDFs that must stay searchable, use the light preset instead of a KB target.
Nothing leaves my computer?
Correct. Open the browser network tab while it runs — no requests are made. That matters for ID documents and financial papers.
What if it cannot reach the target?
It returns the smallest version it could make and tells you. Very detailed colour scans sometimes cannot go below ~30 KB per page.
