Media convert tool

iMediaTool is a complete video and audio toolbox that does everything on your phone — nothing is ever uploaded. Convert and compress video (H.264/H.265, MP4/MKV/MOV, up to 4K) with one-tap presets for LINE, Instagram, YouTube, WhatsApp and email. Cut, merge, rotate and crop, change speed, reverse, apply colour filters, add watermarks, burn in subtitles, add background music, capture frames or make GIFs. For audio, work with MP3 (CBR/VBR), AAC, M4A, FLAC, WAV, Opus, AC-3 and DTS: cut, merge, change speed and pitch, edit tags and cover art, make ringtones, and add fades, volume changes, loudness normalisation and noise reduction. iMediaTool reads DTS and AC-3 soundtracks most phones cannot play, upmixes stereo to 5.1 surround, and lets you check every channel with its built-in playback test and channel level meter. Vocal separation, speech-to-subtitles, a processing queue you can pause and reorder, share-to-app, 50 languages and five themes are included, on phones, foldables and tablets.
