Why Use This PDF Compressor?
Exam portals (SSC, UPSC) and government portals (UIDAI, PF) have incredibly strict requirements for uploading documents like Aadhar cards, PAN cards, or caste certificates. They typically demand files under 500KB and reject standard PDFs generated by mobile scanners.
100% Offline & Secure
Unlike other popular PDF tools that force you to upload your sensitive ID proofs to their cloud servers, FileHubTools uses advanced WebAssembly to compress the PDF directly inside your browser. Your documents never leave your device.
Flattening for Security
When you compress a PDF using our tool, we automatically "flatten" the document. This means any editable fields, hidden layers, or selectable text are fused into a single image layer. Government portals prefer flattened PDFs because they cannot be easily tampered with or modified.
