File type conversion can be achieved using online tools, desktop software or command line tools. Online tools allow uploading files and selecting the desired output format, while desktop software requires installation and importing files for conversion. Command line tools require specific commands in the terminal. Additionally, manually renaming the file will change the file type, but may result in the file being unable to be opened.
How to change the file type
1. Use an online file conversion tool
- Access online file conversion tools such as Zamzar, CloudConvert or FileConverto.
- Upload the files to be converted.
- Select the desired output file type.
- Click the Convert button.
2. Use desktop file conversion software
- Install file conversion software, such as AnyMP4 Video Converter Ultimate or Movavi Video Converter.
- Open the software and import the files you want to convert.
- Select the desired output file format.
- Click the Convert button.
3. Use the command line tool
- to open a command line terminal (such as Windows Command Prompt or macOS Terminal).
- Navigate to the directory containing the files you want to convert.
- Use one of the following commands:
- Windows:
ffmpeg -i input.mp4 output.avi
- macOS:
avconv -i input .mp4 output.avi
(replace input.mp4
and output.avi
to match your filename and desired output format)
4. Manually rename the file (not recommended)
- Navigate to the directory containing the file you want to convert.
- Right-click the file and select "Rename".
- Add the desired extension to the end of the file name (e.g.
.avi
or.pdf
).
Note:
- Some file types may not be converted.
- Online conversion tools usually have file size limits.
- Manually renaming the file may make the file unopenable.
