Frequently Asked Questions
Detailed answers regarding our WebAssembly architecture, privacy guarantees, pricing value-exchange, and developer API integrations.
Is it really 100% private?
Yes. For 95% of formats, our Rust-compiled WebAssembly engine runs directly in your browser's sandboxed memory. No bytes ever leave your device or touch an external network. For complex CAD/video formats that require ephemeral edge worker isolates, isolate memory is completely destroyed within 30 seconds of completion.
How do rewarded ads and offerwalls work if I don't want to pay?
If you exceed your daily quota of 5 free cloud edge conversions, you can watch a 15-second sponsor video or complete an interactive survey on our offerwall to earn 3 instant conversion credits without entering credit card details.
What is the maximum file size supported?
Free in-browser WASM conversions can process files up to 2GB depending on your device RAM. Cloud edge conversions for free users are capped at 50MB per file; Pro users can upload and process up to 2GB per file across all audio, video, and 3D CAD engines.
Can I integrate OpenFileConverter into my own application via API?
Yes. We offer both a high-throughput REST API and Cloudflare Worker Service Bindings for zero-latency in-isolate byte conversions. Explore our interactive API documentation and token management dashboard to generate production keys.
“Converting 500MB video files without waiting 10 minutes for cloud uploads saved our design agency hundreds of hours per month.”

“Zero retention wasn't a nice-to-have for our legal compliance team—it was mandatory. OpenFileConverter is the only converter we allow across our organization.”
