About the Base64 to Image

This takes a Base64 string or a full data URL and renders it as an image you can view and download. It is the counterpart to inspecting an API response or a database column that stores images as text rather than as files.

If nothing renders, the usual causes are a truncated string, a missing or wrong MIME type in the data URL prefix, or content that was never an image to begin with. The prefix matters: `data:image/png;base64,` and `data:image/jpeg;base64,` are not interchangeable, and browsers vary in how forgiving they are.

Frequently asked questions

My Base64 has no data: prefix. Will it work?

Yes — pick the image type from the dropdown and the tool builds the data URI for you. If the input already starts with data:image/..., that prefix is used and the dropdown is ignored.

The image shows as broken. Why?

Usually the Base64 is valid but the declared type is wrong — for example, PNG bytes labelled as JPEG. Try switching the image type. The other common cause is a truncated string, which the validator will catch.
