Help
Everything you need to install, set up, and get unstuck. Files never leave your device.
Install on your Mac
Download the .dmg from the download page, open it, and drag TeraConvert into your Applications folder. The app is built for macOS on Apple Silicon (M1 and later).
The app is signed and notarized. On first launch macOS shows a standard confirmation, so click Open. If macOS says the app cannot be checked, right-click the app in Applications and choose Open once. It opens normally every time after that.
Extra conversion tools
Images, video, audio, PDFs, text and image OCR work the moment you open the app, because TeraConvert ships its own copies of FFmpeg, Tesseract, qpdf and pdfium, and macOS handles most images and documents with its own tools. The formats left over, office files, ebooks and a few document conversions, use open-source engines that install through Homebrew.
Set up nothing in advance. When a file needs one of those engines the app says so, installs it in one click, and finishes your conversion on its own once the download completes. If Homebrew is not on your Mac yet, install it from brew.sh first, then come back and drop the file again.
Troubleshooting
A conversion failed. What now?
First press Retry, since most failures are a tool that was still installing. Open Technical details on the error card to see which engine ran, then check that its tool is installed under Settings. If it fails again with the same file, the source may be corrupt, so try another file to narrow it down.
Are there file size limits in the browser?
The browser converts one file at a time within size caps: images up to 25 MB, video up to 500 MB, audio up to 100 MB, and PDFs up to 100 MB. Larger files, batch conversion, and more formats need the Mac app. Your first conversion is free, so you can test your file before you buy Pro.
A format is not supported in the browser.
The website converts 200+ pairs in the browser, which covers the common ones. The desktop app handles 800+ supported conversions using native engines, so formats like HEIC, AIFF, and EPUB route there. When you drop such a file on the website, it points you to the desktop app for that job.
OCR is missing words from my scan.
The built-in OCR reads printed text and clean layouts well. Handwriting, stylized fonts, and dense multi-column pages fall outside what it targets, so results there are partial. For higher accuracy on difficult scans, the desktop app runs Tesseract with more language packs.
The app will not open on first launch.
The app is signed and notarized, so first launch shows a standard macOS confirmation where you click Open. If macOS says it cannot check the app, right-click TeraConvert in Applications and choose Open once. macOS remembers your choice and opens it normally after that.
How do I update?
The desktop app checks for updates on launch and every few hours, then installs them in the background. You can also open Settings and choose Check for Updates to update right away. Updates are included for everyone who owns Pro.

Uninstall
Quit the app, then drag TeraConvert from Applications to the Trash. Tools you installed through Homebrew stay in place because they are standard system packages you may use elsewhere. Remove any you no longer want with brew uninstall.
