01 / CONSTRAINT ANALYSIS
Private, Instant PDF Size Reduction
Most online PDF compressors upload your confidential contracts, financial audits, and medical records to external cloud servers. For sensitive documents, this presents an unacceptable compliance and privacy risk.
Bitmorfy performs document optimization directly in your browser session using pdf-lib. It rebuilds the cross-reference table, enables Flate stream compression on uncompressed objects, and discards duplicate embedded resource dictionaries.
Your document never leaves your machine, making it fully compliant for legal, corporate, and personal privacy requirements.
