Convert MP4 to FLAC directly on your device for enhanced security and privacy. Our local conversion process means your videos are not uploaded to our servers, guaranteeing the confidentiality of your files, especially important for sensitive or personal data.

Audio parameters

Audio Bitrate:

Audio bitrate is a key determinant of audio quality and file size, measured in kilobits per second (kbps). Common bitrate values range from 128 kbps, suitable for standard quality, to 320 kbps for high-quality audio. In professional settings, bitrates can be even higher. Our tool allows you to choose from a variety of bitrate options, enabling you to strike the perfect balance between sound quality and file size based on your specific needs, whether it's for casual listening or high-fidelity audio playback.

Sample Rate:

The sample rate, measured in hertz (Hz), defines how many times the audio is sampled per second. Standard CD-quality audio uses a sample rate of 44.1 kHz, while professional audio recordings often use 48 kHz or higher, up to 192 kHz for high-resolution audio. Our conversion tool lets you adjust the sample rate to suit your requirements, offering the flexibility to choose between standard quality for everyday use and higher rates for detailed, professional-grade audio production.

Introduction to FLAC Format

High-Quality Lossless Audio

FLAC, or Free Lossless Audio Codec, stands out for its ability to compress audio without any loss of quality. This ensures that the audio remains true to the original recording, making it a preferred choice for audiophiles and professionals seeking pristine audio fidelity.

Efficient Compression and Metadata Support

Despite being lossless, FLAC efficiently reduces file sizes to about 50-60% of their original size. It also supports rich metadata, including artist and track information, as well as album art, enhancing the listening experience.

Wide Compatibility

FLAC is supported by a vast array of playback devices and software, ranging from dedicated audio players to smartphones and home entertainment systems. This wide compatibility, combined with its high-quality audio, makes it a versatile choice for various audio applications.

Introduction to MP4 Format

Definition of MP4

MP4, or MPEG-4 Part 14, is a digital multimedia container format, used for storing video, audio, and other data such as subtitles and images. It's highly popular for streaming over the internet and boasts extensive compatibility with various devices and software.

Broad Compatibility

MP4 is known for its broad compatibility with a wide range of digital devices and playback software, making it a universal format for digital media storage and streaming.

Efficient Compression

With its efficient compression capabilities, MP4 allows for high-quality video and audio content to be stored in relatively small file sizes, facilitating easier streaming and downloading.

What Happens When Converting MP4 to FLAC

Audio Extraction

The conversion process involves extracting the audio part from the MP4 file. This step isolates the audio data, preparing it for conversion into the FLAC format.

Format Conversion

After extraction, the audio is converted to FLAC format. This process involves encoding the audio data into FLAC's lossless compression format, ensuring no loss of audio quality.

Quality Preservation

Given FLAC’s lossless nature, the conversion aims to preserve the highest possible audio quality from the original MP4 file. This ensures that the output maintains the integrity of the original audio.

Considerations When Converting MP4 to FLAC

File Size

FLAC files, being lossless, are larger in size compared to lossy formats. It's important to consider storage capacity when converting to FLAC.


While FLAC offers superior audio quality, it's crucial to ensure that your playback device or software supports the FLAC format.

Privacy and Security

For MP4 files containing sensitive information, choose a conversion service that ensures privacy. performs conversions locally on your device, preventing your data from being uploaded to external servers and maintaining confidentiality throughout the conversion process.
