Decoded image bytes stay in your browser; nothing is uploaded.
Large Base64 strings use a Web Worker above 500 KB.

Base64 to Image
Paste a raw Base64 string or full data URI to reconstruct an image in your browser. The tool normalizes whitespace and padding, detects common image formats, previews the result, and downloads the decoded file instantly.
Base64 to Image Use Cases
- Recover images copied from API payloads, JSON blobs, or database exports
- Preview data URIs before shipping them into HTML, CSS, or emails
- Normalize copied Base64 strings that contain line breaks or missing padding
- Download decoded assets quickly for manual QA or design review
Base64 to Image FAQ
Can I paste a full data URI instead of raw Base64?
Yes. The tool accepts both raw Base64 payloads and complete data URIs such as data:image/png;base64,....
What happens if the MIME type is missing?
The decoder first inspects the binary signature of common image formats. If no type can be inferred, you can choose a fallback output type for the preview and download.
Will it fix whitespace or missing padding?
Yes. The tool strips whitespace, normalizes URL-safe Base64 characters, and adds missing padding when the input can still be decoded safely.
Does the Base64 input stay private?
Yes. Decoding runs entirely in your browser, and large inputs are moved to a Web Worker so the page remains responsive.
