## What is FormatFox?

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. Nothing is 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.
