What this tool does
Base64 to Image decodes image data URLs or Base64 image strings into previewable image files.
← All Tools
🖨️ Base64 to Image
Paste a Base64 image string or data URL, preview it, and download the decoded image.
Why it is useful
It helps debug API payloads, CSS data URLs, email assets, generated images, and embedded image snippets.
How it works
The browser reads the Base64 string, detects the image type when possible, and previews or downloads the decoded image.
Best input
Use a complete data URL or a Base64 string from a known image type.
Debugging tip
If decoding fails, check for missing prefixes, whitespace, truncated strings, or non-image data.
Privacy note
Decoding happens locally in your browser.
Important limitation
Base64 image strings can be very large and may exceed browser memory or page limits.
Quick answers
Does Base64 mean encrypted?
No. It is just an encoding.
Can I decode any file?
This page is intended for images; other binary files may not preview correctly.
Common Use Cases
Preview an API image payload
Paste a data URL or Base64 response body to confirm the image renders before wiring it into an app.
Recover an embedded asset
Decode CSS, email, or JSON image snippets into a downloadable file for inspection or reuse.
Debug broken Base64 output
Check whether a string is missing its media prefix, contains whitespace, or was truncated during transport.
Image Toolkit workflow
Move between compressing, resizing, converting, cropping, encoding, favicon generation, resolution math, and palette extraction while keeping image pixels local to the browser.
