How Online File Conversion Works
MasterConverter transforms documents, images, audio, and video using our own dedicated server-side engines. Every file is processed safely with strictly bounded resources:
Strict File Security & User Privacy
Unlike other websites, we never sell your data, monetize your documents, or send files to third-party conversion APIs.
- Isolated Storage: Uploads and conversion results are stored outside the public web root in private directories.
- Signed One-Time Downloads: Download URLs use cryptographically signed tokens that expire automatically.
- Automatic 60-Minute Wipe: An automated background sweep permanently deletes input and output files from the server.
- No Accounts Required: Convert files anonymously without handing over your email address or personal credentials.
