Songs, sets, split recordings — stitched into a single MP3, in your order. Never uploaded.
Drop audio files here or click to browse
MP3, WAV, M4A, OGG — even video soundtracks. Reorder below, join, download one MP3. Nothing is uploaded.
Merge songs without a server
A DJ set from singles, an album ripped into pieces, chapters of an audiobook: joining MP3s is one of the oldest jobs on the internet, and most sites still solve it by making you upload every song and wait. QuietPix runs FFmpeg in your browser instead — the merge happens at your machine's speed, works offline once the page is loaded, and your music stays yours.
Order matters, so the queue is explicit: reorder with the arrows until the tracklist reads right, then join. Gapless, sample-to-sample, no added silence. To cut an intro or trim dead air first, use the audio trimmer, then come back. For mixed-format piles — not just MP3s — the same engine powers theaudio joiner.
Frequently asked questions
How do I join MP3 files into one?
Drop your MP3s, put them in order with the arrows, click Join. You get a single MP3 with the tracks back to back, made entirely in your browser — nothing is uploaded.
Do the joined MP3s lose quality?
The tracks are decoded, concatenated sample-to-sample and re-encoded once at 192 kbps — transparent for speech and casual listening. There is no second-generation stacking of encodes per track.
Can I mix MP3s with other formats?
Yes. WAV, M4A, OGG, FLAC and even the audio track of a video can sit in the same queue; everything is normalized to one sample rate and stereo layout before joining.
Is there a limit on the number of songs or total length?
No. Your device does the work, so a hundred tracks or a two-hour set are fine — longer jobs simply take longer. No caps, no watermark, no account.
Are my songs uploaded?
No. The audio engine (FFmpeg compiled to WebAssembly) downloads once and runs on your device. Your files never leave your computer.
