How it works
Three steps, all of them on your device.
1. Drop file
Drag a file in or pick one — nothing leaves your device yet.
2. Local WASM processing
Your browser's own WebAssembly engine converts it, entirely on-device.
3. Instant save
Download the result immediately — no upload, no queue, no server.
Frequently asked questions
- Do you store my files?
- No. Conversion happens entirely in your browser via WebAssembly. Files are never uploaded to any server.
- Why does the first conversion take longer?
- The WebAssembly engine (~30MB) has to load once per browser tab. Every conversion after that is fast.
- Is there a usage limit?
- 10 conversions per hour per IP address, with files up to 500MB — just to prevent abuse. No accounts, no upgrades, no catch.
