Frequently Asked Questions

What does Base64 to Image do?

The tool decodes a Base64 string or data URI and shows the image, which you can download as a file.

What is a data URI?

A data URI contains MIME type and Base64 data inside the URL, for example data:image/png;base64,...

Can I paste plain Base64 without data:image?

Yes. If MIME type is missing, the tool tries to detect the image type from content or lets you choose it manually.

Which image formats are supported?

Main formats: PNG, JPEG, WebP, GIF, and SVG if the browser can preview them.

Why is preview not shown?

Base64 may be corrupted, MIME type may be wrong, or the browser cannot display that format. Try choosing MIME type manually or verify the string.

Can I download the image?

Yes. After decoding you can download the image with the chosen file name and appropriate extension.

Is it safe to paste SVG?

SVG may contain scripts or external links. Before using SVG on a site, inspect and sanitize it with separate tools.

How is this different from Image to Base64?

Base64 to Image decodes a string back to an image. Image to Base64 does the opposite: encodes an image file to Base64 or data URI.

Is data sent to the server?

No. Base64 is decoded locally in your browser and not sent to the server.

Do I need to register?

No. The tool works immediately and does not require registration.
