How Our PDF Tools Work
Everything runs directly in your browser — privately, instantly, and securely. Here's how we deliver professional-grade PDF editing without uploading your files.
Your PDFs Never Leave Your Device
Macix uses advanced client-side technologies (WebAssembly, Web Workers, Offscreen Canvas) to process every action locally. This ensures total privacy — ideal for corporate, legal, academic, and financial documents.
- Zero uploads — fully browser-based
- Professional-grade PDF engine
- Compatible with all major browsers
A Simple 3-Step Workflow
1. Load Your PDF
Choose any PDF on your device. The file stays fully local — not a single byte is uploaded.
2. Apply Tools & Transformations
Merge, split, compress, rotate, convert, reorder, watermark, extract — all processed instantly within your browser.
3. Download the Result
Once complete, save the processed PDF or extracted files with a single click. No compression tricks, no quality loss.
Powered by WebAssembly
Our PDF engine is compiled to WebAssembly (WASM) — the same technology behind high-performance desktop apps — and runs at near-native speed in your browser.
- Over 10× faster than classic JavaScript solutions
- Optimized for large files (100–500MB PDFs)
- Ideal for professional workflows and teams
Only Pay for Successful Actions
No subscriptions. No monthly contracts. You simply use tokens for each successful operation — predictable, affordable, and flexible.
- Tokens deduct only on success
- No charge for errors or failed files
- Top up anytime
Merge & Split
Smart page rendering and structure parsing let you reorganize documents with total control.
Compress & Optimize
Advanced compression algorithms reduce size by up to 70% while preserving readability.
Convert & Extract
Extract text, images, or convert pages into JPG — perfect for design, research, or republishing.
Enterprise-Level Security
Because everything runs locally, even sensitive corporate documents remain fully private. No uploads, no servers, no data retention.
- Zero-knowledge processing
- No data storage or logs
- Ideal for legal & compliance workflows
