Frequently Asked Questions

Will this always get my PDF under 100KB?
This tool compresses PDF overhead — cross-reference tables and metadata. PDFs with uncompressed structure can see significant size reduction. Heavily scanned or already-optimised PDFs may not reach 100KB; consider splitting or reducing image content for those.
Is my file uploaded to a server?
No. Compression runs entirely in your browser. Your PDF never leaves your device.
