Why offline is the point
Every free converter online works the same way: your file goes to their server.
Online converters what you give up
- Your file leaves your computer. Contracts, invoices, medical scans, client drawings
- Free tiers cap files per day and often add a watermark
- Broken on planes, air-gapped machines, and restricted networks
- The service can change, monetise, or vanish — and the files went there anyway
FormatMagician local engine
- Nothing is transmitted. No telemetry, no analytics, no upload
- Unlimited batches — drag a folder, get a folder back
- Works with the network disconnected, which is also your proof
- Common formats are free; the full version unlocks the advanced ones without a subscription
