Very easy but also very useful one, changing a file format e.g. a .wma file to .mp3 file
Changing a file format
- Use Google to search for what you want to go from and to (e.g wma to mp3, HEIC to jpg etc)
- Open one of the websites from the results, the two I use most ffrequently are CloudConvert and FreeConvert
- Upload the file to the website, change any settings to fit your needs and hit convert
- Download finished file (sometimes websites auto download upon completion)
