Can I paste the full data URI?

Yes. The tool removes the data:image/svg+xml;base64 prefix before decoding.

Does Base64 decoding optimize the SVG?

No. It only decodes. Use SVG Optimizer afterward if you want a smaller file.

Does it validate output?

Yes. The decoded text must parse as SVG before results are shown.

Is Base64 to SVG free?

Yes. SVGKit tools are free to use with no account required.

Does Base64 to SVG upload my files?

No. The tool runs entirely in your browser, so your files never leave your device.

What input does Base64 to SVG accept?

The supported formats are listed on the input control above; the tool validates input and reports a clear error for anything it cannot parse.

Is the output production-ready?

Yes, the output is standards-based markup. Preview it at the sizes where it will ship before replacing a production asset.

Why does the output differ slightly from the input?

Formats support different features, and conversion preserves what the target format can represent. Differences concentrate in gradients, filters, and interactive features.

Where Base64 to SVG fits

Base64 to SVG decodes raw Base64 strings or Base64 SVG data URIs back into SVG markup.

Supported inputs

The tool accepts raw Base64 text and full data:image/svg+xml;base64 URIs.

UTF-8 handling

Decoded bytes are read as UTF-8 so SVG files with Unicode text can round-trip correctly.

Conversion is a translation between formats: Base64 to SVG preserves what the target format can represent and previews it before export.

How the conversion works

Base64 to SVG parses the input in your browser, applies the target format's rules, and produces standards-based output without a server round-trip. The page shows the result before you commit to it.

What to expect from the output

Formats have different capabilities, so conversion is a translation rather than a perfect copy. Check dimensions, colors, and any interactive features in the preview, since those are the areas where formats differ most.

Getting the best results

Clean input produces clean output. Start from the simplest version of the source that still renders correctly, keep explicit dimensions or a viewBox, and test the result where it will actually ship.

Privacy

Conversion runs locally in your browser. Base64 to SVG never uploads your content to a server, which also makes it safe for confidential assets.

How to use

Paste Base64. Paste raw Base64 text or a Base64 SVG data URI.
Decode. The tool converts the payload back to SVG text.
Copy SVG. Copy the decoded SVG for editing or saving.
