FAQs for MP4 Converter
Common answers so you can keep moving.
Which files can I use with MP4 Converter?
The upload area shows which file types are accepted. If a file is rejected, convert it first or check that its extension matches its real type.
Is my file uploaded?
Small image conversions can run in your browser; most other conversions are processed on our servers and the file is removed afterwards by an automated cleanup job.
The conversion failed or never finished
Check that the file opens correctly on your device and is not password protected or corrupted, then try again. Very large files can fail on slow connections; try a smaller file or a different browser.
The result looks different from the original
Different formats store different features. Check whether the target format supports what you used (transparency, animation, fonts) and choose another format if it does not.
