What to check in the finished file
The goal is a usable result, not merely a file with a new extension. For this workflow, convert MOV videos to MP4 right in your browser. Files never leave your device.. Keep an untouched original until you have confirmed that the output works in its destination app and that no expected content is missing.
- Open the saved file and confirm it is complete and readable or playable.
- Compare the output with the original, especially text, dimensions, audio and page order where relevant.
- Check that the file meets the target app’s upload, compatibility or size requirements.
Common problem and how to avoid it
Converting a container may require transcoding and can change the output size. If the first result does not meet the requirement, return to the original and adjust the relevant settings rather than repeatedly converting an already degraded output.
