Why In-Browser PDF Compression is Better

Email providers and job application portals frequently impose file size ceilings (such as 2MB or 5MB). High-resolution document scans, print-ready graphics, and embedded fonts can quickly balloon a PDF to tens of megabytes.

Our local optimizer parses PDF object streams, eliminates redundant cross-reference data, and compresses internal assets right inside your browser RAM. Your private files are never uploaded to remote cloud servers, guaranteeing absolute confidentiality.
