LocalConvert
The file converter that never uploads your files

Free · iOS 16+ · iPhone & iPad · 30+ languages
Most file converters send your files to someone else's computer
Online converter websites work by uploading your document to a server, converting it there, and sending it back. Your contract, ID scan, or client data sits on infrastructure you don't control. LocalConvert takes the opposite approach.
Online converter websites
- Your file is uploaded to a remote server before anything happens
- You depend on the site's retention policy and security practices
- Ads, trackers, and upload caps on many free tiers
- Useless without a connection — slow on bad Wi‑Fi
LocalConvert
- All conversions happen on your device — files never upload to servers
- No analytics, no tracking, completely private
- No file size limits and no server delays — conversion at device speed
- Works fully offline: airplane mode, subway, anywhere
