About Merge Audio
This tool allows you to merge multiple audio files into a single file by concatenating them in the order you upload them. Perfect for combining podcast segments, music tracks, or any audio files that need to be joined together. Supports various audio formats including MP3, AAC, and WAV.
- Input
- Use the formats listed in the file chooser. Decoding depends on the selected tool and browser.
- Output
- Download the result in the format shown beside its filename. Batch ZIP is available only where the result area offers it.
- Processing
- The current implementation processes the selected files on this device. Processing libraries, language data or models may be downloaded separately; these resource requests do not require uploading the selected file.
- Limits and behavior
- File capacity depends on device memory and input encoding. Large or unsupported files can fail; encrypted PDFs may need to be unlocked before use. There is no site-wide file-size guarantee.
