What's the best way to convert MP3 to FLAC on Windows 11?

I wanted to convert MP3s to FLAC before, and I didn't want to install any additional software. Later, I found that Windows' built-in function can also do it. Although it is a bit cumbersome, it is absolutely safe and suitable for people who need simple conversion. The following are the specific steps, which can be regarded as a hidden MP3 to FLAC method.

Steps:

1. Find Windows Media Player on your computer and drag the MP3 files to be converted into the media library.
2. Click the "Burn" option, drag the MP3 files to the burning area on the right, and create an audio CD list.
3. If your computer has an optical drive, you can burn it directly to a physical CD; if you don't have an optical drive, use the virtual CD tool to create a virtual disc, and then burn the audio CD to the virtual disc.
4. Extract to FLAC file:

Click "Tools > Options > Extract Music".

• In the extraction settings, set the output format to FLAC and select the appropriate audio quality.
• Return to the main interface, select the burned CD, and click "Extract Music". Windows will extract and convert the audio tracks to FLAC format and save them to the specified folder.
• Check the extracted files to confirm that all MP3s have been successfully converted to FLAC, and the process is complete.

I think this method is suitable for small batch conversions. It is completely completed by the system's own functions and does not require downloading any third-party software. It can also be regarded as a hidden MP3 to FLAC conversion trick. Although the efficiency is average, it is absolutely safe and reliable, especially for friends who need to convert occasionally. I hope it helps you!
