Frequently Asked Questions

AudioFlow Metadata Editor supports all major audio formats including MP3, FLAC, MP4, and M4A. The tool can read and write ID3 tags in these formats, with full support for embedded album artwork and extended metadata fields. WAV files are supported for reading metadata but have limited tag writing capabilities due to format constraints.

Absolutely secure! Mqtech.site processes all files entirely within your browser using client-side JavaScript. Your files never leave your device or get uploaded to any server. We don't store, track, or have access to any of your audio files or metadata. This approach ensures complete privacy and eliminates any security concerns about sensitive or copyrighted material.

After editing your metadata, click the "Save Changes" button in the Export section. The tool will create a new file with your updated metadata and automatically download it to your device. The original file remains unchanged for safety. You can choose different ID3 versions and export options based on your compatibility needs.

For optimal compatibility and quality, we recommend 500x500 pixels or larger square images in JPEG format. Most music players and streaming services display album art at 500x500px, but higher resolutions (up to 1400x1400px) are supported for future-proofing. PNG format is also supported but creates larger file sizes. Avoid very large images (over 2MB) as they can significantly increase file size.

The auto-fill feature analyzes your filename and attempts to extract metadata using common naming patterns. It works best with structured filenames like "Artist - Title.mp3", "01 - Song Title.mp3", or "Artist - Album - Track Title.mp3". The tool recognizes various separators (dashes, underscores, spaces) and can parse track numbers, artist names, and song titles automatically.

Yes! Use the Copy Metadata and Paste Metadata buttons to transfer metadata between files. Edit the first file completely, copy its metadata, then load each subsequent file and paste the metadata. This is perfect for album tracks that share artist, album, year, and genre information. You can then adjust individual track titles and numbers as needed.

First, ensure you're using a modern browser (Chrome, Firefox, Safari, Edge) with JavaScript enabled. Clear your browser cache and try again. If you encounter issues with specific files, try a different audio file to determine if it's file-specific. For corrupted or unusual file formats, the tool may export metadata as a JSON file instead of embedding it. Check the browser console (F12) for detailed error messages.

Custom tags allow you to add specialized metadata not covered by standard ID3 fields. Use them for information like BPM, Key Signature, Mood, Producer, Remix Info, or Recording Location. These tags are particularly useful for DJ libraries, music production, or detailed cataloging. Note that custom tags may not be displayed in all music players, but they're preserved in the file for applications that support them.
