Our Mission

Every PDF tool. One simple workspace.

DocuNexa was built to eliminate the chaos of sketchy PDF websites filled with popup ads, file size throttles, and privacy risks.

We believe your documents belong to you. We do not store, view, or train models on your uploaded files.

Created with students and teachers in mind, making 800-page textbooks easy to digest as modular unit PDFs.

Our page-slicing and PDF engines preserve original vector graphics, embedded fonts, and print resolutions.

High-quality document tools should be universally accessible without paywalls on essential productivity.

In-Memory Processing: Documents loaded into memory via ArrayBuffer APIs and discarded upon tab closing.

MIME & Byte Validation: Strict file structure verification prevents binary execution or corrupted streams.

Safe Filename Sanitization: Automatic stripping of forbidden characters, preventing filesystem collisions.

No Tracking Pixels: Zero third-party behavioral analytics or invasive telemetry injected into documents.

Offline Capability: Web Worker based processing functions reliably even with intermittent connectivity.

File System Access API: Direct local folder saves without double browser downloads where supported.
