How to Convert MP4 to FLAC Online & on Desktop
Import Your MP4 File
Open the MP4 to FLAC converter in your browser or launch the desktop software, then upload or import your MP4 video. Online tools are ideal for quick audio extraction, while desktop programs are better suited for large files, longer videos, or managing multiple conversions locally.
Select FLAC Output and Customize Audio Settings
Choose FLAC as the output format whether you convert MP4 to FLAC online or on desktop. You can keep default settings for fast results, or adjust sample rate, channels, and bitrate in the desktop converter to ensure high-quality, lossless audio output for music or professional use.
Convert, Save, and Review Your FLAC Audio
Start the MP4 to FLAC conversion and save the extracted audio file once processing is complete. Download it from the online tool or access it locally on desktop, then play and review the FLAC file to ensure the sound quality meets your expectations for playback, editing, or archiving.

Key Features of UniConverter MP4 to FLAC Converter
High Quality MP4 to FLAC Without Extra Loss
Extract audio from MP4 to FLAC using a lossless process that avoids additional compression. While converting from a lossy source cannot magically restore missing detail, it preserves the existing quality as faithfully as possible for editing, archiving, or careful listening.
Online MP4 to FLAC Conversion with No Installation
Convert MP4 to FLAC online directly in your browser for quick one‑off tasks. Upload a single video, choose FLAC as the output, and download your audio in minutes. The web tool is free to use, requires no registration, and does not support batch processing or parameter tweaks.
Batch MP4 to FLAC for Large Libraries
Handle dozens or hundreds of videos with the desktop MP4 to FLAC converter. Import multiple MP4 files, queue them together, and let the software process them in bulk while you work on something else. This batch capability is only available in the desktop version, not online.
Advanced FLAC Output Settings on Desktop
Fine‑tune your FLAC exports in the desktop app by adjusting sample rate, bit depth, channels, and bitrate‑related options. Create profiles for different workflows, such as 16‑bit FLAC for distribution or higher resolution for mastering. Online conversion does not offer export parameter control.
Simple Workflow for Extracting Audio from Video
Follow a streamlined workflow designed for all skill levels. Drag and drop MP4 files, select FLAC, and start converting in a few clicks. Clear labels, presets, and built‑in tips help you move from basic extraction to more advanced audio conversion when you install the desktop version.
