Passthrough Video Converter

Passthrough converts compatible videos to MP4 on your iPhone, iPad, or Apple silicon Mac using Apple's AVFoundation. THREE PRESETS • Fast Passthrough preserves existing media streams when the source and MP4 container support them, avoiding re-encoding when possible. • Compatible 1080p exports a broadly compatible MP4 up to 1080p. • Efficient HEVC 1080p exports an HEVC MP4 up to 1080p. Output size depends on the source and preset. SIMPLE FILE WORKFLOW On iPhone and iPad, tap Add Videos to choose a movie in Files, select a preset, and tap Start. Completed files are saved in Passthrough's Converted Videos folder. Tap Share or Save to send a result to a destination you choose. To use a video from Photos, first save it to Files from Photos. On Mac, add videos, choose an output folder, select a preset, and click Start. Use Show to locate a completed file in Finder. SAFE OUTPUT Source files are not modified or deleted. Output files receive unique names instead of overwriting existing files. Passthrough validates the output's size, video track, and duration before assigning its final name. LOCAL CONVERSION No account, advertising, analytics, subscription, or developer-operated video upload service is used. Conversion runs on your device. File providers and sharing destinations you choose may use their own services. SUPPORTED INPUT AND LIMITATIONS Choose media supported by your device, including compatible MP4, MOV, and M4V files. Compatibility depends on the source media and selected preset; unsupported combinations display an error. Keep the mobile app in the foreground until conversion finishes. The queue is not restored after closing the app.
