Different volumes stay different. Normalize in an editor if the joins sound jumpy.
When Audio Joiner is the right page
Audio Joiner sits on this site because Audio and Audio are not interchangeable, even when they look similar in a file list. Stick two or more clips together into one file. Use the general audio tool when you know the player and you need to choose the target yourself. Use the general audio tool when you know the player and you need to choose the target yourself.

What you give up by leaving Audio
The converter reads the audio you upload and writes a new file in the format you pick. A named pair such as WAV to MP3 is clearer when you already know both formats. Lossy to lossless does not improve the take.
Keep the original recording.
What you gain, and do not gain, with Audio
Audio Joiner keeps the format family as Audio and still changes the file you can use. Use the general audio tool when you know the player and you need to choose the target yourself. MP3, WAV, AAC, OGG, FLAC, AIFF, Opus, and M4A are available after the converter loads once.
Convert only audio you have the right to use. The first run downloads the converter.
A test that matches the real file
Start from the question the other software asked. If it asked for Audio, Audio Joiner is the matching page. If it asked for something else, switch tools instead of hoping a similar extension will pass. Stick two or more clips together into one file. Files are joined in the order you add them and exported as one audio file. The limit is the part people skip, and it is the part that decides whether the download is usable. Different volumes stay different. Normalize in an editor if the joins sound jumpy. The file stays on your device. The first run downloads a converter, so keep this tab open. A phone runs out of memory on long files. A computer is the safer place for a big clip. Check three things in the download: it opens, the Audio material you cared about is still there, and the file size or the layout is what the form described. A new extension alone is not those three things. If a portal, a teacher, or a client rejects the file, send them the original Audio as well when you are allowed to. Audio Joiner is a convenience copy. It is not a new master. Audio conversions are one-way once the format is lossy. Audio Joiner can change the container or the codec so a player opens the file. It cannot make a muffled take clearer, and it cannot turn an MP3 into a studio master by calling the result WAV or FLAC. Finish the edit on the best copy you have, then make the share file once.
Here is the decision for Audio Joiner. You start with Audio and you stop when a real program accepts Audio. MP3, WAV, AAC, OGG, FLAC, AIFF, Opus, and M4A are available after the converter loads once. A named pair such as WAV to MP3 is clearer when you already know both formats. Lossy to lossless does not improve the take. If those two sentences describe a tradeoff you do not want, do not convert. Renaming the extension by hand will not do this job. Running the tool twice on its own output will not do it either.

Other jobs start from the homepage, where each tool is named for the conversion it actually does.
