BATCH (PRO) Add or drag several files and Converto converts them one after another, with progress for each file. Drag and drop on iPad and Mac. MORE – Import from Photos, the Files app, drag and drop or "Open in Converto" – Preview before converting: duration, resolution, page count – Keep the original quality with one tap, or fine-tune format, bitrate and resolution – Manage, preview and share your converted files – No ads, no watermarks, no tracking, no size limits FREE AND PRO Converto gives you 3 free conversions to try it out — any mix of images, audio and video. Converto Pro unlocks unlimited conversions and batch conversion, as a monthly or yearly subscription or a one-time lifetime purchase. ON MAC Converto includes a built-in local MCP (Model Context Protocol) server: AI agents like Claude Desktop or Cursor can convert your files through Converto. It runs only on your Mac (loopback, never exposed to the network) and is off until you enable it in Settings.

This one makes long conversions easier to live with, and fixes a few. – A film with more than one language? Choose which audio to keep, in the converted video and when you extract the audio. Works for a whole queue too. – Extract a video's subtitles to SRT or VTT, one file per language. – Videos and queues keep converting when you leave the app, and your iPhone shows how far along they are. Needs iOS 26, and you can turn it off in Settings. – Settings now shows how much space Converto is using, and frees it with a tap. Converted files also has Delete all. – Pick GIF and its width, frame rate and length are right there, not in Settings. – iPhone photos converted to WebP keep their colors. – On iPhone and iPad, 5.1 audio now converts to stereo too. It used to fail. – FLAC follows the channels and sample rate you choose. – Numbers and plurals are right in every language. – In the menu, Photos is now Photo Library, because your videos are in there too. – Large MKV films open using far less memory. – On Mac, iPhone photos keep their colors in every format, and ProRAW photos no longer come out dark. – The format tiles now say H.264 and H.265 next to MP4 and HEVC.
