    Tips

    Tips & Best Practices

    • 1If the image doesn't decode, try a different format (PNG vs JPG) — the format must match the actual image type
    • 2Data URIs start with 'data:image/TYPE;base64,' — if yours doesn't have this prefix, select the format manually
    • 3Very long Base64 strings are normal — a 100KB image becomes ~133KB of Base64 text
    • 4Use the companion 'Image to Base64' tool to go in the other direction
