Guide updated:
Choose a supported target format and review compatibility before starting conversion.
Open this guide using the “How to use this tool” link below the tool name. It includes steps, screenshots and videos for computers and phones.
Before you start
Keep the original video. File extension, codec and player compatibility are different things.
Try with a demonstration file — video.mp4
These small files were created for this guide and contain no personal data.
Step-by-step instructions
- Choose the source video and wait for its details and conversion settings.
- Select a target format supported by the device or application where you will use it.
- Review the available quality, size and codec options. Avoid enlarging a small source without a reason.
- Check the displayed price or confirmation, start conversion and wait for the result.
- Play the new file, check its picture and sound, and save the converted copy.
On a computer
Use the full-width working panel to compare the source, settings and result. Keep the original file so you can try another setting without replacing it.
On a phone
Choose the source from Files or your device file manager. Scroll down to the settings and result; keep this tab open until the operation finishes.
In Safari on iPhone, open the sharing menu and choose Save to Files if the result opens in a new tab. In Android Chrome, check Downloads. Keep this tab open until processing finishes.
For a better result
A broadly supported container alone does not guarantee playback; the codecs inside it also matter.

Questions and troubleshooting
Why is the output bigger than the source?
A higher bitrate, less efficient codec or different quality setting can increase file size.
Can conversion recover missing detail?
No. A larger resolution or bitrate cannot recreate detail that was absent from the source.
If you see a message that the service is overloaded, wait and try again later. A failed attempt does not mean that your source file has changed.
