How to convert Base64 to SVG

1. Paste Base64 input

Paste a data URL or raw Base64 string. We will clean up line breaks and missing padding automatically.

2. Preview and download

Check the preview, then download the converted file when the conversion finishes.

Paste Base64 input

Paste a data URL or raw Base64 string to begin the conversion.

Auto-fix common issues

We remove line breaks, fix padding, and normalize URL-safe Base64 when possible.

Input type detection

We detect the image type from the Base64 data to guide the output.

SVG output

SVG is editable and scalable for design work.

Save the converted SVG file to your device.

Still-image conversion

If the pasted data contains an animated format other than SVG, conversion exports one decoded frame.

Frequently Asked Questions

Yes. The converter will try to detect the image type. If detection fails, add a header like data:image/png;base64,...

The Base64 string may be incomplete or include invalid characters. Make sure you copied the full value.

We read the data URL header when available and confirm the file signature from the data.

Downloads use a base64-image filename with the selected extension.

If the encoded file is already SVG, its bytes are decoded directly. If an animated GIF, WebP, or AVIF must be converted to SVG, only one decoded frame is exported.
