data:image/*;base64,string into the input. - The preview appears instantly if the Base64 is valid.
- Click Download to save the decoded file.
Benefits & key features
- Quickly inspect images embedded in HTML / email source.
- Detects file type automatically from the MIME prefix.
- No server round-trip — works offline and with confidential content.
- Helpful when debugging chat apps that share images as Base64.
Pro tip
If the preview stays blank, the Base64 string is probably missing the data:image/png;base64, prefix. Prepend it and try again.
