Base64 to Image
Convert Base64 to image, decode data URI strings, and preview the result without uploading files.
Concept
How to validate image data from Base64
This tool restores image assets from Base64 text and lets you verify the result immediately before using it elsewhere.
Use it when an API response, email body, or JSON payload includes embedded image text and you need a fast check of whether it is a real image.
It distinguishes `data:image/...` URIs that include MIME metadata from raw Base64 values, so you can paste both forms and confirm what will be rendered.
Input types
Supports data URI format like `data:image/png;base64,...` and raw Base64 without prefix, including whitespace and line-break-heavy payloads.
Verification checklist
Check MIME type consistency, estimated file size, and decode success to filter out malformed Base64 or mismatched image metadata.
Source safety
The decode happens in-browser only, but verify the origin of the embedded image string (API contract, sender identity, hashes) before reusing it.
A concise decision aid for teams debugging images embedded in API responses, email content, and JSON data.

Frequently asked questions
What Base64 input can I use?
You can paste a data:image/... data URI, and Base64 without a prefix is treated as a PNG image for preview and conversion.
Can I view and save the decoded image result?
Yes. Once the decoded Base64 image is displayed, you can save it with the download button.
Why is the image not displayed?
The preview can fail if the string is not a valid Base64 image or if the MIME information does not match.
