Best Practices for Album Artwork
- Use square images - 500×500, 1000×1000, or 1400×1400 pixels work best
- Keep file size reasonable - Under 1-2MB to avoid bloating audio files
- Use high quality - Clear, professional-looking artwork displays better
- Prefer JPEG for photos - Better compression for photographic artwork
- Use PNG for graphics - Better quality for text and sharp edges
Pro Tip: When adding album art to MP3 files, use square images (same width and height) for best compatibility across all music players and devices. Most music apps display 300×300 or larger artwork, so aim for at least 500×500 pixels. Our tool uses FFmpeg to embed the image as an ID3v2 tag with proper metadata, ensuring compatibility with iTunes, Spotify, VLC, Windows Media Player, and all modern music players. The audio itself is not re-encoded, preserving 100% of the original audio quality - only the metadata is modified to include the cover art!
