FormatFox: File Converter

FormatFox is a free iPhone app that converts images, PDFs, and audio entirely on your device — no subscription, no uploads, and no account. It converts HEIC, JPG, and PNG, resizes images, and combines multiple photos into a single PDF, all offline. A one-time Pro unlock adds batch conversion and audio transcoding to M4A, WAV, AIFF, and CAF.

Most converters meter you to one file, hide a weekly subscription behind the Save button, or quietly upload your private files to a server. FormatFox does none of that. Every conversion runs 100% on your device. Your files are not uploaded. It even works in Airplane Mode.
