Questions about Audio Joiner
Can I join files of different formats?
Yes. Each file is decoded to raw samples, then resampled to a common rate and channel count before they are concatenated, so MP3, WAV, M4A and OGG can be mixed.
Is there a limit on how many files I can merge?
There is no fixed cap, but long audio is held in memory while it is decoded and encoded, so keep the total reasonable on low-memory devices.
About Audio Joiner
Join multiple audio files into one track with our free online Audio Joiner. 100% browser-based, fast, and private—no login or file uploads required.
These audio tools edit sound without a desktop editor: trim and join clips, convert formats, record from microphone, and adjust volume, speed, pitch or equalisation while you listen to the result.
This tool runs in your browser. The file is not uploaded. Work on a copy and preview before downloading: trimming and speed changes are destructive to the loaded clip, and re-encoding a lossy file twice adds audible artefacts.
