Why Local Compression Guarantees Maximum Privacy
Most online compression services upload your private financial statements, legal briefs, and corporate presentations to third-party cloud machines to perform optimization. This creates an unnecessary attack vector and violates confidentiality agreements.
With ForgePDF, all compression mechanics happen entirely client-side. The file never leaves your computer's RAM, providing strict adherence to global privacy regulations such as GDPR and CCPA.
