Benefits of converting FLAC to MP4
Get broad compatibility across browsers
Switching from FLAC to MP4 means your file now offers broad compatibility across browsers, phones, and smart TVs with efficient H.264/H.265 compression.
Wider compatibility
FLAC is great for lossless compression that preserves full audio fidelity at roughly half the size of WAV, but not every app or device handles it well. Converting to MP4 sidesteps that, so the file opens wherever you need it to.
No quality compromise
ConvertFastHub runs FFmpeg at production settings, preserving as much of the original FLAC fidelity as the MP4 format allows.
Keep your original too
Converting doesn't touch your source file — you get a brand-new MP4 file back and can keep both versions.
