Frequently Asked Questions
What is Base64 encoding?
Base64 is a method of encoding binary image data into ASCII text characters. This allows images to be embedded directly in HTML, CSS, or JavaScript code without needing separate image files. Useful for small icons, logos, or when you need self-contained code.

Upload your image, and our tool instantly converts it to Base64 encoded text. Click "Copy" to copy the Base64 string to your clipboard, then paste it directly into your HTML, CSS, or JavaScript code. The entire process happens in your browser instantly.
How do I use Base64 images in HTML?
After converting your image to Base64, use it in HTML like: <img src="data:image/png;base64,YOUR_BASE64_STRING">. This embeds the image directly in your HTML without needing external image files. Perfect for email templates or single-file HTML documents.
How do I use Base64 images in CSS?
Use Base64 images in CSS background properties: background-image: url(data:image/png;base64,YOUR_BASE64_STRING);. This eliminates additional HTTP requests and keeps your CSS self-contained. Ideal for small icons, buttons, or loading indicators.
What image formats can I convert to Base64?
Convert JPG, JPEG, PNG, WEBP, and GIF images to Base64 encoding. All common web image formats are supported. PNG is recommended for images with transparency, while JPG works best for photographs.
Should I use Base64 for large images?
Base64 encoding increases file size by about 33%, so it's best for small images (icons, logos, buttons) under 50KB. For larger images, regular image files with HTTP caching are more efficient. Our tool shows character count to help you decide.
Why use Base64 images in web development?
Base64 images reduce HTTP requests, eliminate external dependencies, work in email templates, simplify single-file distributions, and ensure images always load even when offline. Perfect for email newsletters, small icons, and embedded resources.
Are my images uploaded to your servers?
No! Your images never leave your device. All Base64 encoding happens entirely in your browser using client-side JavaScript. This ensures instant results, maximum privacy, and works offline. Your images and Base64 output stay 100% private.
