Convertly PDF & File Converter

Convert files right on your iPhone. PDFs, photos, video, audio and documents — compress, merge, split, change format, or scan to a searchable PDF. Nothing is uploaded, there's no account, and no sign-in. Every conversion runs entirely on your device.

Most file converters send your files to a server. Convertly doesn't. There's no network code, no analytics, and no tracking — your files never leave your phone. That makes it faster, it works offline, and it means a private document stays private.

PRIVATE BY DESIGN
No account. No sign-in. No servers. No analytics. No ads that follow you. Your files are processed on your iPhone and stay there.

A couple of honest notes
• There's no MP3 export — iPhones can play MP3s but can't create them, so audio is saved as M4A/AAC, the closest high-quality equivalent.
• A few older or uncommon video formats (MKV, WebM, WMV, FLV) can't be opened on iOS — the app tells you clearly instead of failing quietly.
