Frequently asked questions
- What's the difference between a data URL and a raw base64 string?
- A data URL looks like
data:image/png;base64,iVBORw0KG...— it already says what format the image is. A raw base64 string is just theiVBORw0KG...part with no format info, so you need to tell this tool what format it is using the dropdown. - Why did it fail to preview?
- Either the base64 text is incomplete/corrupted, or the format you selected doesn't match what the data actually is — try a different format from the dropdown if you're not sure.
- Is my data uploaded anywhere?
- No — decoding and preview both happen entirely in your browser.
