What Base64 is

Base64 turns binary data into plain text so images can travel inside JSON, HTML, CSS and emails. Decoding reverses that: the text becomes the exact original bytes again, bit for bit.

What happens when you convert

Paste a data URL or raw Base64 string and this tool decodes it locally, detects the image type from its bytes, and saves it as a SVG file. Nothing is sent anywhere.

Base64 to SVG FAQs

What does the Base64 decode to?
SVG is text, so the Base64 is decoded to SVG markup and saved as a .svg file you can open in a browser or vector editor.
Where do I get a Base64 string?
From APIs, JSON payloads, CSS files and HTML emails. Many services embed images as Base64 text instead of separate files.
What if the string is invalid?
The tool shows an error instead of converting. Check that you copied the complete string with no missing characters.
Is the decoded file identical to the original?
Yes. Base64 is just a text encoding of the exact bytes, so decoding restores the original file bit for bit.
Are my files uploaded to a server?
No. The conversion runs entirely in your browser with local code. Your files never leave your device.
