What formats can be decoded?

Any image format encoded in Base64 can be decoded — PNG, JPG/JPEG, GIF, WebP, SVG, BMP. The format is identified from the data URI header or detected from the decoded data.

What if my Base64 string doesn't start with 'data:'?

If you have a raw Base64 string without the data URI prefix, the tool can still decode it — you may need to specify the image format so the correct MIME type is used for the decoded file.

Why is my decoded image corrupted?

Corrupted output usually means the Base64 string is incomplete or contains invalid characters. Check that you copied the complete string and that no whitespace or line breaks were accidentally inserted.

Can I convert Base64 images found in HTML source code?

Yes. Copy the Base64 string from the src attribute of an img tag (everything after 'data:image/...;base64,') and paste it into the decoder.

Is there a size limit for Base64 strings?

The tool handles Base64 strings up to approximately 7MB (representing ~5MB decoded images). Very large Base64 strings may cause browser performance issues.

What is Base64 to Image Converter?

The Base64 to Image Converter decodes Base64 strings and data URIs back into viewable, downloadable image files. Paste any Base64-encoded image string or complete data URI and the tool displays the decoded image with download options in the original format.

This is the reverse operation of image-to-Base64 encoding. It's useful for extracting images from Base64 data in JSON APIs, HTML email sources, database BLOBs, and code repositories where images are stored as Base64 strings.

Why Use Base64 to Image Converter?

When images are stored or transmitted as Base64 strings in code, APIs, or databases, you need to decode them back to image files for viewing, editing, or analysis. This tool makes that conversion instant without requiring developer tools or code.
