Why Client-Side Compression?

Most online compressors require sending your proprietary PDFs, personal photos, or internal business records to third-party cloud servers. File2File re-engineers compression to run inside your browser. Your data never leaves your device RAM, guaranteeing complete GDPR, HIPAA, and enterprise compliance.
