What is How to Convert?

How to Convert product thumbnail

How to Convert is a desktop file converter for people who need to change formats without sending files to a cloud service. Users can right click a file or drag files into the app, then convert, compress, crop, resize, or trim them using local conversion tools behind a graphical interface. The app supports more than 6,000 conversions across images, video, audio, documents, email, and subtitles on Mac, Windows, and Linux.

Why How to Convert works

Searching for a one off converter often means uploading a private file to an unfamiliar server or wrestling with command line tools for a simple format change. How to Convert puts those conversion tools behind right click and drag and drop controls while processing files locally, so a format change stays on your computer instead of passing through an unknown server.

How to Convert features

  • Local file conversion. Files are processed on the computer rather than uploaded to external servers. The desktop app can run completely offline after its initial license validation.
  • Over 6,000 conversions. One app handles thousands of combinations across images, video, audio, documents, email, and subtitles.
  • Right click conversion. Convert or compress files directly from their folder. The same menu can also crop images and trim audio or video.
  • Batch processing. Drop multiple images, videos, or documents into the app and convert them together instead of processing each file separately.
  • Compression and format controls. Resize and compress images, adjust video resolution and codecs, extract audio, and choose lossless or lossy PDF compression.

Who How to Convert is for

  • People handling private documents or media who do not want files uploaded to a third party conversion server.
  • Designers and content creators regularly moving between image, audio, and video formats who want those jobs in one desktop app.
  • Nontechnical users who need tools such as FFmpeg, Pandoc, LibreOffice, or ImageMagick without working through shell commands.
  • People processing folders or photo collections who need to convert several files in one batch.
