Free and unlimited use:

Our service is entirely free and without limits. Use it anytime, anywhere, for as many conversions as you need, without any restrictions.

Audio Size Preview:

Our audio size preview feature provides an estimate of the file size after conversion, regardless of the format. This tool helps users gauge whether the new file size meets their needs and storage capabilities, making it easier to decide on the conversion parameters for formats ranging from compressed to uncompressed audio.

Custom Quality:

Our conversion tool offers customizable options for audio bitrate and sample rate, allowing users to fine-tune the quality of their audio files. Whether you're converting to a format for professional use or casual listening, these settings provide the flexibility to optimize audio quality according to your specific requirements.

Fast conversion:

We value your time. Our service efficiently converts your AAC files to high-quality FLAC format, allowing for quick access to your uncompressed audio files.

Cross-Platform Accessibility: is accessible on any device with an internet connection. Convert AAC to FLAC effortlessly on your desktop, tablet, or smartphone, anytime and anywhere.

Privacy Protection:

Your privacy is our top concern. We ensure that your files are never stored on our servers, maintaining the security and confidentiality of your data.

Local Conversion:

Enhance your security by converting AAC to FLAC directly on your device. Our local conversion process prevents your audio files from being uploaded to our servers, protecting 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

Definition of FLAC

FLAC, which stands for Free Lossless Audio Codec, is an audio format known for its lossless compression of digital audio. Unlike lossy compression formats, FLAC retains the complete audio quality of the original source while still reducing file size. It's widely used by audiophiles and in applications where audio quality is a top priority.

Lossless Quality and Efficient Compression

FLAC's main advantage is its ability to compress audio without any loss of quality, offering a perfect digital copy of the original audio. This makes it ideal for high-quality audio storage, archival purposes, and audiophile music listening.

Compatibility with High-Fidelity Audio Systems

FLAC is supported by a growing number of high-fidelity audio systems and software players. It's becoming increasingly popular among users who demand the highest audio fidelity, including music enthusiasts and professionals.

Introduction to AAC Format

Definition of AAC

AAC, or Advanced Audio Coding, is a lossy digital audio compression format. It was designed as a successor to the MP3 format, with improved audio quality at similar bit rates. AAC is widely used in various digital platforms and streaming services due to its efficiency and quality.

Superior Audio Quality in a Compressed Format

AAC is celebrated for providing better audio quality than MP3 at the same bit rates, making it a preferred choice for efficient digital audio compression in consumer electronics and broadcasting.

Broad Device and Platform Compatibility

As a modern audio format, AAC is widely supported across various digital devices and platforms, making it a versatile choice for audio playback and distribution in the digital age.

What Happens When Converting AAC to FLAC

Conversion to a Lossless Audio Format

Converting from AAC to FLAC involves transforming the lossy compressed AAC file into the lossless FLAC format. This process allows for the preservation of the best possible audio quality from the AAC file, but it's important to note that any quality lost in the original AAC compression cannot be restored.

Increase in File Size

Since FLAC is a lossless format, converting from AAC will result in a significant increase in file size. This is a crucial factor to consider, especially if storage space is a concern.

Enhanced Audio Quality for Archiving and High-Fidelity Playback

By converting to FLAC, you ensure the highest possible audio quality for archiving and playback, particularly suitable for high-fidelity audio systems and critical listening environments.

Considerations When Converting AAC to FLAC

Evaluating the Need for Lossless Audio

Before converting to FLAC, consider whether the benefits of lossless audio justify the increased file size. FLAC is ideal for archival and high-quality audio playback but may be excessive for casual listening or portable devices with limited storage.

Understanding the Implications for Storage

Be aware that converting from AAC to FLAC will significantly increase the file size. Ensure that you have adequate storage space to accommodate these larger files, especially if you are converting a large music library.

Selecting Appropriate Conversion Software

Choose a conversion tool capable of handling the AAC to FLAC conversion without compromising the integrity of the audio data. Ensure that the software can effectively manage the conversion process, keeping in mind the specific needs of lossless audio formats.

Security in Conversion

For audio files with sensitive content, opt for a service that upholds privacy. performs AAC to FLAC conversions directly on your local device, ensuring absolute confidentiality and security of your files. This local conversion method safeguards your data from being uploaded to external servers and provides protection throughout the conversion process.
