How do I use Base64 in React?

Import as: import logo from './logo.png'; then use . Or paste Base64 directly: .

Should I Base64 images in React?

For small icons/logos used in components, yes. For large images, use imports or public folder with webpack optimization.

Can I use Base64 in React Native?

React Native does not support data URIs well. Use require() for local images or URI for remote images instead. 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.

How do I optimize Base64 in React?

Use React.memo() for components with Base64 images. Consider code-splitting and lazy loading for large Base64 strings. Everything is processed locally in your browser, so your files never leave your device.

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.

React Base64 Encoder — For React

React Base64 Encoder

Use Base64 in React. In React, inline small icons with a Base64 src, or let the bundler auto-inline assets under ~4KB.

Why it matters: In React, inline small icons with a Base64 src, or let the bundler auto-inline assets under ~4KB. Generate the string here and drop it straight into your code.

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: Encode your asset above, then paste the Base64 into your React project.

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.
