Base64 to SVG, explained
SVG is different from raster formats: it's text-based vector markup, not pixels. This decoder turns a Base64 SVG string back into editable .svg markup you can preview, copy, or download. Because SVG is vector, it scales to any size without blur.
When to choose SVG
- Icons, logos, illustrations. Crisp at every resolution.
- You need to edit the source. SVG is plain XML you can open and tweak.
- Small, reusable assets for CSS. Common in sprites and inline styles.
What you can paste
- A full data URI —
data:image/svg+xml;base64,PHN2Zy.... Names the exact format, most reliable. - A bare Base64 body — decoded as SVG.
Private by design
Decoding uses the browser's native image handling — the string is turned into an image element locally and never sent anywhere. Safe for confidential assets.

Frequently asked questions
How do I convert a Base64 string to an SVG?
Paste the Base64 string or full data URI into the box and click Decode to SVG. The vector previews and you can download the .svg file or copy the markup.
Why use SVG instead of PNG?
SVG is vector, so it stays sharp at any size and is usually smaller for line art and logos. PNG is better for detailed photos.
Is the decoder private?
Yes. Decoding happens entirely in your browser. Nothing is uploaded, so your data stays on your device.
