Cloud Converters vs. Client-Side Architecture
Cloud PDF Converters
- ✕Remote Server Upload: Private files travel across the web to cloud servers. This can risk your private data.
- ✕Data Retention Risk: Files may stay on cloud disks for hours or days. This increases the risk of data leaks.
- ✕Privacy Rules Risk: Sending files to cloud servers can break rules like GDPR and HIPAA.
- ✕Paywalls & Limits: Many sites force file quotas, wait queues, paywalls, and ugly watermarks.
Client-Side Memory Sandbox
- ✓Zero Network Use: Files run in your device memory with WebAssembly. Exactly zero bytes leave your machine.
- ✓Safe Memory: Your browser clears the temporary memory the moment you close the tab.
- ✓Strict Privacy: Complies with GDPR and HIPAA because no files are ever sent to a remote server.
- ✓100% Free Forever: Unlimited processing, exact KB targets, and zero watermarks on your files.
The Client-Side Document Processing Pipeline
Here is how our client-side runtime processes your files with mathematical precision:
File Loads Directly in Device Memory
When you pick a file, your browser loads it into temporary device memory. No network request is made. The file stays only on your device.
Local Document Parsing
Our code parses the PDF layout. It organizes the text, fonts, and pages. Text and shapes stay sharp without any loss.
Fast In-Browser Processing
Fast WebAssembly code runs your task. It compresses, rotates, or encrypts the PDF. It keeps text crisp and clean.
Instant Download & Safe Memory Cleanup
Your browser creates the new PDF file. You can download it right away. Your browser clears the temporary memory when you leave the page.
