How do I convert a Base64 string to an image?

Paste the Base64 string into the input box and click Convert to Image. The tool accepts both raw Base64 text and a full data URI such as data:image/png;base64,.... The image appears in the preview pane with its format, dimensions and estimated file size listed underneath.

Can I use a data URI with the prefix included?

Yes, and it is often the safest option. The tool detects the MIME type directly from the prefix when it is present, so unusual formats are recognised reliably. When no prefix is given, the format is detected from the magic bytes of the decoded data.

Which image formats are supported?

PNG, JPEG, GIF, BMP, WebP and SVG are recognised by the tool. PNG and JPEG are detected by their signature bytes, and SVG is detected as text. Format conversion for downloads is available between PNG, JPG and WebP using the built-in canvas re-encoding.

Does the tool upload my Base64 image to a server?

No. The entire conversion, preview and download process runs locally in your browser. Nothing is transmitted, stored or logged, which makes the tool suitable for Base64 strings taken from private emails, databases or internal systems.

How can I tell how large the decoded image is?

The metadata panel shows the detected format, the pixel dimensions, the estimated decoded file size and the length of the Base64 string. The file size is estimated from the Base64 length with a 3-to-4 ratio, so it is accurate rather than approximate.

Why does the tool say my Base64 is not a valid image?

Either the string is not valid Base64, it is incomplete or truncated, or it decodes to data that does not match a recognised image signature. Check that the whole string was copied, then try including the full data:image/...;base64, prefix.

Can I convert the image to another format on download?

Yes. Choose PNG, JPG or WEBP from the download dropdown and the tool re-encodes the image through a canvas before saving. JPG output is filled with a white background first, since JPEG has no alpha channel.

What is the difference between a data URI and raw Base64?

A data URI is raw Base64 plus metadata: it starts with data:image/png;base64, and tells any consumer the MIME type. Raw Base64 is just the encoded data. This tool accepts both, using the prefix when present and falling back to magic-byte detection when it is not.

Can I paste the Base64 from an email attachment?

Yes, and this is one of the most common uses. Find the image in the message source, copy the full data URI segment, and paste it here. The tool strips stray line breaks and produces a clean, downloadable image file.

Why is my SVG not recognised?

SVG is text rather than binary, so it has no magic bytes to detect. Include the full prefix, such as data:image/svg+xml;base64,...., and the tool will identify it and render the preview correctly.
