Base64 to SVG
Paste a Base64 string or a data:image/svg+xml;base64, URI below and click Decode Base64 to SVG. The decoder checks the file signature, shows a preview and lets you download the result as a real .svg file.
How to convert Base64 to SVG online
- Paste the Base64 value into the input box. Data URIs, whitespace and line breaks are handled automatically.
- Press Decode Base64 to SVG.
- Check the preview and the detected file type, dimensions and size.
- Click Download to save the .svg file.
Important notes about the decoder
- The decoder detects the real file type from the decoded bytes (magic number). If your string is not actually SVG, you will see the real type and can still download it.
- Invalid characters are reported instead of silently producing a broken file. If decoding fails, try the Base64 repair tool.
- Nothing is uploaded: the data is decoded locally by your browser, so even confidential documents stay on your device.
About SVG
SVG is an XML-based vector format: shapes are described with text instead of pixels, so the image stays sharp at any size. It is ideal for icons, logos and illustrations.
Since SVG is already text, you can also embed it URL-encoded instead of Base64, which is often smaller. Base64 is still the safest choice when the markup contains quotes or characters that would break your CSS or HTML.

Frequently asked questions
How do I convert Base64 to SVG?
Paste the Base64 string into the box above and click "Decode Base64 to SVG". You can preview the result and download it as a .svg file.
Why is my Base64 SVG not displaying?
Usually the string is truncated, contains URL-safe characters, or was double-encoded. The decoder reports the exact problem; the Base64 repair tool can fix most of them automatically.
Do I need to remove the data URI prefix?
No. The decoder strips "data:...;base64," automatically and uses the MIME type from it as a hint.
