FormatFox: File Converter

Batch & audio, 100% offline

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

FormatFox converts images, PDF and audio on your device. Conversions work offline, your files stay local, and Pro is a one-time unlock, not a subscription. 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. FREE, forever: • Convert HEIC, JPG and PNG • Resize images • Combine photos into a single PDF • See the exact before → after size of every file PRO — one simple, one-time unlock (no subscription): • Batch-convert many files at once • Transcode audio: M4A, WAV, AIFF, CAF • Quality & compression control • Keep EXIF metadata • "Convert with FormatFox" share action from any app • Remove ads No account. No login. No tracking of your files. Just convert and get on with your day. Recommendations for our other apps load online.
