AppConvert turns your files into the format you need — and does it on your phone.
Out of 110 tools, 105 run entirely on your device. Your video never leaves it, your documents are never uploaded, and nothing waits in a queue on a server. Turn on aeroplane mode and they still work.
WHAT YOU CAN CONVERT
• Video — MP4, MOV, MKV, AVI, WebM, HEVC, ProRes. Compress a video, extract its sound, turn a clip into a GIF.

NO SIZE LIMIT
A two-gigabyte video is a two-gigabyte video. There is no upload to wait for and no cap to run into — only the free space on your phone.
TRIM AND SPEED, BEFORE YOU CONVERT
Video and audio tools come with a player. Set the start and end of the extract, change the speed, and hear the result before the conversion starts.
IT KEEPS WORKING WHEN YOU LEAVE
A long encode continues in the background. Leave the app, take a call, come back when it is done.
THE FIVE TOOLS THAT NEED A CONNECTION
Office documents require a full office suite, far too heavy for a phone. Word, PowerPoint and Excel to PDF, PDF to Word and text recognition are therefore handled on our servers. Each one is marked with a cloud icon before you choose it, so you always know where your file goes.
