Official Commitment: We never store, log, analyze, or train AI on your uploaded files. Ever.
OpenFileConverter is engineered from the ground up as a stateless conversion engine. Our legal and architectural guarantee ensures that your confidential documents, tax forms, photos, and CAD models remain entirely in your control.
OpenFileConverter Privacy Architecture & Zero-Retention Commitment
How our dual-runtime architecture guarantees zero file leakage across all platforms
The Client-Side Sandbox
95% of standard conversions (PDF, HEIC, WebP, SVG, MP3, ZIP) run directly inside your local browser memory using Rust WebAssembly and SIMD acceleration. Your files are never sent across the internet, guaranteeing zero network transmission and total immunity from server-side interception.
Ephemeral Cloudflare Pyodide Isolates
For massive files (>128MB) or legacy codecs requiring cloud execution, jobs execute in isolated, RAM-only Cloudflare V8 sandboxes. No persistent hard drive disk writes ever occur. The isolate memory space is cryptographically shredded and recycled within 30 seconds of job delivery.
