Upload a FLAC file and shrink its size. FLAC audio is lossless, so it shrinks by lowering the sample rate and bit depth.
Your file never leaves your device. All processing happens right in your browser, and nothing is uploaded to a server.
FLAC is already losslessly compressed, so the tool shrinks it by reducing the audio resolution: sample rate, bit depth, or both. The output is still FLAC, lossless at its new, lower resolution.
A 24-bit 96 kHz studio master downsized to 16-bit 44.1 kHz keeps CD quality at a fraction of the size, which is plenty for everyday listening.
Hi-res purchases and Bandcamp downloads often carry resolution far beyond what playback gear reproduces. Downsampling keeps you in the lossless world while reclaiming real space. When maximum shrinkage matters more than losslessness, FLAC to M4A or MP3 goes much further.
