Base64 to SVG Converter

Decode a Base64 string or SVG data URL, preview the image, and save the SVG file. Your data stays in your browser.

Stays in your browser

Paste raw Base64, an SVG data URL, or CSS url(...).

{{ inputCharCount.toLocaleString() }} characters

Decodes automatically after you paste. Up to 8 MiB of input text.

Input cleanup: {{ result.fixes.join(', ') }}.

SVG preview

Decoded SVG preview

Your SVG preview will appear here.
Try the sample to see how it works.

The SVG was decoded, but the browser could not display it. You can still inspect or save the source below.

Check the input message to continue.

Decoding your input. SVG decoded. {{ outputSize }} ready to save.

Background choices only change the preview. Your SVG stays unchanged.

The preview uses image mode, so scripts do not run and external resources do not load. Downloads and copied source preserve the original SVG. Review SVG from an unfamiliar source before embedding it in a page.

How to convert Base64 to SVG

1. Paste or load the encoded text

Use raw Base64, an SVG data URL, or a CSS url(...) value. You can also load a text file or try the sample.

2. Check the decoded SVG

Review the preview, file size, and SVG source. Switch the preview background to check white or transparent artwork.

3. Download or copy the source

Save the .svg file or copy its markup for your editor. The decoded SVG is preserved without tracing or rasterizing it.

Keep the SVG source

Recover the encoded SVG markup, including paths, text, and the viewBox. Decoding does not turn it into a pixel image.

Use the string you have

Paste Base64 or a data:image/svg+xml URL. URL-encoded SVG data URLs and CSS url(...) wrappers work too.

Check before downloading

Preview the image, compare light and dark backgrounds, and inspect the decoded SVG source and file details.

Decode on your device

Your encoded text and SVG stay in your browser. No upload, account, or software installation is needed.

More ways to work with SVG

SVG to Base64

Need the reverse? Turn an SVG image into Base64 for an HTML, CSS, or API field.

SVG to PNG

Create a PNG copy when your upload form or image editor needs pixels instead of SVG.

Use Base64 in CSS and APIs

Check data URL syntax, SVG embeds, and payload size before adding an image to your project.

Frequently Asked Questions

Paste the complete Base64 string or SVG data URL into the input. Check the preview and decoded source, then select Download SVG. You can also copy the SVG markup into a text or vector editor.

Yes. Paste the entire data URL, including its prefix, or use only the raw Base64 after the comma. The tool also accepts URL-encoded SVG data URLs without the ;base64 marker and a data URL wrapped in CSS url(...).

Yes. This tool restores the SVG bytes in your encoded input without rasterizing, tracing, or optimizing them. Paths and text stay as encoded. If the SVG already contains an embedded pixel image, decoding does not turn that image into vector paths.

This decoder needs SVG data. Base64 only stores a file as text; it does not change its format. For PNG or JPG data, use Base64 Decode Image to recover the image first, then choose an image-to-SVG tool if you need tracing.

The value may be incomplete, contain invalid Base64 characters, or decode to something other than SVG. Copy the full value, including any ending equals signs. The tool handles line breaks, missing padding, and URL-safe Base64 where possible, but cannot restore missing image data. Input text is limited to 8 MiB.

Try a different preview background for white or transparent artwork. SVGs that depend on external images, styles, fonts, or scripts can look different in an image preview. Check the source and its width, height, and viewBox; decoding cannot restore resources that were not included.

No. Decoding happens in your browser, and the preview displays the SVG as an image. The downloaded source is preserved, including any scripts or external references it originally contained. An image preview is not a security check; only reuse SVG content you trust.
