Encountering a "broken image" icon instead of your expected visual? Troubleshooting Base64 image errors usually comes down to a few common culprits.
Common Error 1: Invalid Data URI Prefix
A valid Data URI must start with the correct header. If it's missing or misspelled, the browser won't know how to render it.
- Correct:
data:image/png;base64,... - Incorrect:
data:png;base64,...orbase64,...
Common Error 2: Truncated Strings
Base64 strings are massive. If even a few characters are missing at the end due to a copy-paste error, the entire image will fail. Always use the "Copy" buttons in our encoder to ensure you get the full string.
Common Error 3: Improper Padding
Base64 strings often end with one or two = characters for padding. Stripping these can sometimes break older browsers or specific decoders.
