Image to Base64
Encode your images to Base64 strings for direct embedding in CSS, HTML, or JSON. Processed locally, 100% fast and secure.
1. Select Image
Upload File
JPG, PNG, WebP, SVG
2. Base64 Output
Data URI includes the data:image/png;base64, prefix. Raw is just the encoded string.
How to Convert an Image to Base64?
Upload your Image
Select or drag and drop any web image (JPG, PNG, WebP, SVG, or GIF) into the left upload panel.
Instant Encoding
Your browser instantly reads the file natively and generates the encoded Base64 string in real-time.
Copy to Clipboard
Choose between the raw string (for APIs) or the full Data URI (for embedding in HTML/CSS) and click copy.
Why Use Our Base64 Encoder?
A crucial tool for front-end developers aiming to reduce HTTP requests and optimize web performance.
100% Private & Serverless
We don't want your images. The entire encoding process utilizes your browser's native FileReader API, meaning your images are never sent over the network.
Reduce HTTP Requests
By converting small icons and logos into Base64 Data URIs and embedding them directly into your CSS or HTML, you drastically reduce the number of HTTP requests, speeding up your website.
Frequently Asked Questions
Are my images uploaded to a server to be encoded?
No, your images are never uploaded. The Base64 encoding process happens entirely locally within your web browser using HTML5 technology. It is 100% secure.
What is the difference between Raw Base64 and Data URI?
A Data URI includes a media type prefix (e.g., data:image/png;base64,) and is ready to be used directly in HTML `src` tags or CSS `background` properties. Raw Base64 is just the encoded string without the prefix, commonly used for API JSON payloads.
Is there a size limit for images?
While our tool has no hard limits, converting very large images (over 2MB) into Base64 generates massive text strings that can cause your web browser to lag or crash. It is recommended to only use Base64 for small icons and logos.
