Inside ConvertMaster Ultra
Fifty tools, one engine
Convert between video, audio, image and PDF formats. Trim, merge, compress, mute, reverse, boomerang and loop. Extract, boost, normalise and clean up audio with noise reduction and fades. Make GIFs, thumbnail sheets and vertical versions for Shorts, Reels and TikTok. Burn subtitles, add a watermark, create chapters or strip metadata, and turn audio plus a cover image into a podcast video.
A queue you can walk away from
Stack conversions and let them run, with live progress, cancel and retry. Hardware encoders are used where your phone reports them, and Settings tells you plainly what your phone supports. One-tap presets cover Social, Instagram, YouTube and Discord.
Everything in one library
Every output lands in the Library, where you can share, open, save or delete it.
Who it is for
ConvertMaster Ultra is built for creators, students, marketers and podcasters who want to convert media without sending it to someone else’s server.
It sits in the files & transfer part of the catalogue, and your media never leave the phone to be processed. There is no server behind ConvertMaster Ultra to send them to.
Local-first, by design
Plenty of the alternatives send your media to a server to be handled. ConvertMaster Ultra does not. Processing runs on your phone’s own processor, and the videos, audio and images you convert stay where you put them. Not for the conversions, which run on your phone. A connection is used for the ads in the free version and the Pro purchase check.
That is not a setting you enable, it is how ConvertMaster Ultra is built, which is why there is no account to create and no subscription to lapse. Full detail is in the ConvertMaster Ultra privacy policy.
