Understanding PDF Merger

Combining separate PDF reports, signed contract annexures, medical test records, or academic research chapters into a single master file is a regular administrative chore. Many online PDF merging tools enforce restrictive file size limits, charge monthly subscription fees, or upload confidential personal paperwork to unknown third-party cloud servers. **Secure In-Browser Document Merging:** Our PDF Merger runs entirely within your browser client powered by the robust `pdf-lib` engine: - **Zero Cloud Uploads:** Your sensitive contracts, tax records, and legal briefs remain strictly on your physical machine. - **Lossless Assembly:** PDF page trees, vector fonts, embedded graphics, and text layers are copied directly into a newly generated document stream without rasterization, preserving crisp print sharpness. - **Selective Page Extraction:** In addition to combining whole files, you can specify individual page ranges for any document (e.g., `1-5, 8, 11-14`). The merger extracts precisely those designated pages while omitting unneeded sections. - **Fast Reordering:** Easily adjust document ordering using intuitive drag-and-drop or accessible keyboard controls. **Handling Encrypted or Corrupt Files:** If an uploaded PDF is password-protected or encrypted, the system identifies it and displays a clear notification so you can supply an unencrypted copy. Everything runs privately and swiftly in your browser with zero data retention.
