Compress PDF to 100KB Online

Shrink PDF files aggressively for strict application forms and document portals that require very small uploads.

Quick answer

A 100KB target is strict, so image-heavy PDFs may need image downscaling before compression. Keep a readable backup copy if text clarity matters.

Privacy note

Keep the source file saved until the output is verified. Browser-local tools avoid uploads where possible, and heavy conversions use encrypted temporary processing only when the format requires it.
