Converto: File Converter

Convert MKV and WebM to MP4, HEIC to JPG, video to GIF or MP3, PDF to images and images to PDF — on your iPhone, iPad and Mac, with no uploads, no account and no file-size limits.

Converto is a fast, private media converter. Every conversion runs on your device: your files never leave it, and it works offline.

VIDEO

Open MKV, WebM, MP4, MOV and M4V and convert to:
– MP4 1080p — plays everywhere (Apple TV, smart TVs, PCs): H.264, Full HD, HDR converted to SDR
– MP4 720p — smaller files for sharing
– MP4 original quality — repackaged with no re-encoding when possible, in seconds
– MOV, M4V and HEVC (H.265)
– Animated GIF — choose frame rate, width and length
– ProRes on Mac

MKV to MP4 and WebM to MP4 are repackaged on device without re-encoding: H.264, HEVC, VP9 and AV1 video with AAC, AC-3, E-AC-3, MP3 or Opus audio (VP9 and Opus require a recent iOS; VP8 and Vorbis are not supported).

VIDEO TO AUDIO

Extract the soundtrack from any video to MP3, M4A, ALAC, FLAC or WAV. When a film has more than one language, choose which audio track to use — for the converted video too.

SUBTITLES

PDF
