Should I Base64 encode SVG?

Sometimes. SVG is already text-based, so Base64 adds 33% overhead. Often better to use raw SVG or URL-encoded SVG instead.

What is better: Base64 SVG or URL-encoded?

URL-encoded SVG is smaller and more readable. Use Base64 only if you have special characters that are hard to URL-encode.

Can I edit Base64 SVG?

Decode it first, edit the SVG code, then re-encode. Base64 is not human-readable. Everything is processed locally in your browser, so your files never leave your device. This keeps your data private and avoids waiting for server processing.

Does Base64 SVG scale?

Yes! SVG remains scalable after Base64 encoding. It is still a vector format, just encoded as text. Everything is processed locally in your browser, so your files never leave your device. This keeps your data private and avoids waiting for server processing.

Is this tool free to use?

Yes. There is no charge, no account, and no watermark on the output. Everything is processed locally in your browser, so your files never leave your device. This keeps your data private and avoids waiting for server processing.

SVG to Base64 — Svg To Base64

SVG to Base64

Convert SVG to Base64. SVG is already text-based and vector, so it stays scalable and resolution-independent as Base64.

Why it matters: SVG is already text-based and vector, so it stays scalable and resolution-independent as Base64. Generate the string with no uploads.

How to convert an image to Base64 (and back)

1Choose Encoder to turn an image into Base64, or Decoder to turn a string back into an image.
2Pick your output — raw, URL-safe, no-padding, or wrapped — and decide whether to include the data: prefix.
3Copy to clipboard or download as a file. Everything runs locally — nothing is uploaded.

Best settings for this page: Upload your SVG image, choose your output format, and copy or download the Base64.

All processing runs locally in your browser. Your images and strings are not uploaded to any server.

Base64 basics: size, data URIs, and when to use it

Size trade-off — Base64 inflates binary data by about 33%. It is best for small assets (icons, logos) and single-file pages; for large images, external files with caching are faster.

Data URI — a data URI is raw Base64 prefixed with a MIME type, e.g. data:image/png;base64,.... Include the prefix for HTML/CSS; store raw Base64 for JSON or databases.

URL-safe — RFC 4648 §5 swaps + and / for - and _ and drops padding, making the string safe for URLs, JWTs, and filenames.

Use it for embedding images in code, email, and APIs where an extra HTTP request is worse than the size cost.
