Processing tips

Save common settings before converting. If keys cannot be derived for new mflac/mgg files, try batching downloaded files from the same source. Failed files are skipped; successful files can still be downloaded.

Select encrypted music

You can select multiple files. Duplicate output names will get a number after the original filename.

Instructions

Software Usage Instructions

Set conversion parameters: First choose the output format, file naming method, ZIP file name, and processing chunks in “Set Parameters.” It is recommended to use “Auto-detect source audio,” so the tool can identify MP3, FLAC, OGG, M4A, or WAV based on the file header.
Configure validation options:
- Automatically detect the real format: Correct the output extension after conversion based on the audio file header.
- Validate output audio: Check whether the conversion result is recognizable audio to reduce invalid files.
- Compress ZIP: Use compression mode when packaging batch results for download.
- Keep unrecognized results: For experimental processing; still allows results to be downloaded when validation fails.
Select encrypted music files: Go to the “Select Files” step, then click the upload area or drag and drop files. Formats such as qmc0, qmc2, qmc3, qmcflac, qmcogg, mflac, mflac0, mgg, mgg0, mgg1, tkm, ncm, and more are supported.
Check the file list: When selecting files in batches, the page only displays the first 20 files, and the remaining files are indicated by count. After processing starts, all selected files will be included.
Start conversion: Go to the “Convert & Download” step and click “Start Conversion.” You can cancel during processing, and completed results will be retained.
Preview and download: A single successful file can be downloaded directly; multiple successful files will be automatically packaged into a ZIP. File names use the original file names by default, and if duplicate names occur, a number will be added after the file name to distinguish them.
Save settings: Click “Save Settings” to save frequently used parameters. They will be applied automatically the next time you open the tool.

FAQ

A: QQ Music QMC series files are supported, including qmc0, qmc2, qmc3, qmcflac, qmcogg, mflac, mflac0, mgg, mgg0, mgg1, tkm, and more; NCM audio restoration is also supported. KGM and VPR can be identified and processed with prompts, but some versions require dedicated mask data.

A: The tool mainly restores encrypted audio data and does not re-encode it. After a normal successful conversion, the audio content will retain the original quality of the source file.

A: mflac and mgg use different versions of encryption methods. The tool will automatically try to derive the mask; if the file uses an independent key or the file itself is incomplete, it may not be possible to restore it. You can try using another file from the same source or process files in batches.

A: We recommend selecting “Automatically detect source audio.” The tool will determine the format based on the restored file header; for example, qmcflac and mflac usually output FLAC, mgg usually outputs OGG, and qmc0 and qmc3 usually output MP3.

A: By default, the original file name is kept and the extension is replaced with the correct one. If multiple converted files have the same name, the tool will automatically add a number after the file name to prevent them from overwriting each other.

A: Processing speed for large files depends on device performance, the number of files, and file size. You can choose a larger processing chunk size in the parameters, convert large numbers of files in batches, and close other resource-intensive programs.
