Why I Built a 100% Client-Side PDF Workspace (Zero Server Uploads)

Most online PDF tools require you to upload confidential documents, contracts, and financial receipts to external cloud servers. Even with strict data policies, server-side processing always poses privacy risks and upload speed bottlenecks.

To solve this, I built NextGen PDF — an entirely client-side web workspace where all PDF operations execute directly inside your browser using JavaScript and WebAssembly.

Why Client-Side Matters:

100% Local Privacy: Documents never leave your machine. No server uploads, zero data logs.
Instant Processing: No waiting in queues or uploading large files to slow cloud servers.
Completely Free: No paywalls, subscription limits, or sign-up gates.

Core Capabilities:

Merge & Split: Reorder, combine, or extract pages on the fly.
Convert Images to PDF: High-speed local conversion from PNG, JPG, and JPEG.
PDF to Images: Extract high-resolution standalone PNGs from document pages.
Zero-Server Workspace: Safe for confidential agreements, IDs, and financial records.

Would love feedback from the DEV community on speed optimizations, UI responsiveness, or features you'd like added next!
