FormatFox is a free iPhone app that converts images, PDFs, and audio entirely on your device ā 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 ā after size of every file PRO ā 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.
