Method 2 - Convert Video to FLAC Online (For Small Files)

If you need to convert a few small video clips and prefer not to install software, consider using an online tool like CloudConvert, which can work right in your browser.

CloudConvert is a popular online file converter that supports various types of file conversions, including video to FLAC. And unlike many other online tools, CloudConvert lets you upload relatively bigger files up to 1 GB. But the tradeoff is the slower processing speed, because it'll take extra time for the upload and relies heavily on your internet connection. Besides, you're allowed to convert at most 10 files per day. So, it'll be a convenient option only if you just want to make a few small file conversions.

⚠️ Privacy Alert: Do not upload personal files because the process takes place on third-party servers.

Step 1: Visit CloudConvert's MP4 to FLAC Converter: https://cloudconvert.com/mp4-to-flac.

Step 2: Click Select File to upload a video or simply drag a file here. You can upload MP4, MOV, WebM, FLV, and many more. It accepts up to 5 files at a time.

Step 3: The output format is already set to FLAC, but you can click Options to adjust the parameters according to your needs. You can also enter the Start time and End time to trim the video.

Step 4: Click Convert to begin the conversion.

Step 5: After conversion, download the converted file to your device.

Method 3 - Convert Video to FLAC with VLC Media Player

This method is especially for users who have already installed VLC media player on their computers. What you might not know is that VLC also includes a basic media converter besides being a media player. While not so intuitive, it gets the job done eventually.

FAQs

1. Does converting a video to FLAC improve sound quality?

If the source video has lossy audio (e.g., AAC in MP4 or Opus in WebM), converting to FLAC won't improve the sound quality, but will keep the exact audio fidelity contained in the source video.

2. Can Windows 10/11 play FLAC natively?

Yes. Both Windows 10 and Windows 11 natively support FLAC audio playback without needing third-party codecs.

3. Is FLAC better than MP3 for video audio extraction?

If you want to preserve the highest audio quality, then yes, FLAC is better than MP3. But if you want smaller files, MP3 is the better choice.
