About this tool

This tool decodes Base64 image data back into a file you can save and open. It accepts full data URIs (data:image/png;base64,…) as well as bare Base64 strings, detects the image type from the data itself, and shows a live preview before you download. Useful when extracting images from API responses, email source, CSS files or database fields.

Frequently asked questions

Do I need to include the data:image prefix?
No. Both full data URIs and bare Base64 strings work — the image type is detected from the decoded bytes.
Why does the tool say my Base64 is invalid?
Common causes are truncated strings (copied partially), URL-encoded characters like %2B instead of +, or line breaks inserted by an email client. The error message indicates what was found.
Is the decoded image private?
Yes. Decoding happens in your browser; the data is never transmitted.
