Base64 to Image Online, Preview and Download
Base64 strings often appear in API responses, CSS, or email. Turn them back into an image to inspect the content.
Base64 cannot be read as an image directly, so a preview helps when checking API responses or web assets. Use the Base64 to image converter to turn the text back into an image file.
How to convert
Paste the Base64 string or the full data URI, then check the preview. If the image does not appear, look for truncated characters or an incorrect data prefix.
- Remove unnecessary spaces and line breaks.
- Make sure the data URI prefix matches the format.
- Check the output size before downloading.
- Do not open strings from untrusted sources.
Practical uses
The tool helps designers and developers inspect assets embedded in code, email, or documentation. Once the image looks right, download it and save it with a clear filename. Everything runs in the browser without sending data to a server.
Save with a clear name
Once the preview looks right, name the file after its context so it is easy to find. If the string came from an email, verify the sender first and do not download suspicious attachments.
Frequently asked questions
What image format is produced?
It follows the data URI format, such as PNG, JPG, WebP, GIF, SVG, or ICO.
Why does the preview fail?
The string may be truncated, contain extra spaces, or have a wrong prefix.
Is it safe to paste a Base64 string?
It is safe when the string comes from a trusted source. Do not open data from unknown senders.
Can I use it for API debugging?
Yes. Paste the Base64 value from an API response to check whether the image is valid.
