Troubleshooting

Windows says "Windows protected your PC". The installer isn't code-signed yet. Click More info, then Run anyway, or install from the Microsoft Store.

A Mac says the app can't be opened, or that Apple can't check it for malware. Try to open it once and click Done, then go to System Settings > Privacy & Security and click Open Anyway (see Installing). The button only appears after you have tried to open the app.

Android won't install the APK. Allow your browser or file manager to install apps when Android asks, and check that the phone runs Android 10 or newer.

Video is slow. Turn on Use graphics card in the Video section (Windows and Mac). Very long or 4K videos still take time.

Text recognition misses words. Use a sharper, straighter photo and choose the right alphabet next to Languages (see Text recognition (OCR)).

A Word or PowerPoint file doesn't look exactly right as a PDF. Install LibreOffice (free) for exact Office layouts (see Documents).

Something else went wrong. Report it from Settings > Your data > Send an error report, or open an issue. On Windows, the file %APPDATA%\Universal Converter\app.log helps to find out why.
