Base64 Image Encoder
Convert images to Base64 strings for direct embedding in HTML or CSS. Encode JPG, PNG, and WebP files to Data URIs to reduce HTTP requests and speed up your site.
About the Base64 Image Encoder
The Base64 Image Encoder converts your image files into a long string of characters (a Data URI). This allows you to embed images directly into HTML or CSS code without needing a separate image file request.
When to use Base64 Images?
Small Icons & Logos
Embedding tiny UI icons directly in CSS saves the browser from making extra HTTP requests, speeding up page load.
Single-File Applications
If you need to distribute an HTML file that works offline without a folder of assets, Base64 images are the solution.
Email Signatures
Some email clients block external images. Embedded Base64 images often display reliably without warning messages.
Frequently Asked Questions (FAQ)
- Does this increase file size?
- Yes. Base64 encoding typically increases the file size by about 33%. It's a trade-off: larger size but fewer network requests. Use it for small images.
- How do I use the output?
- For HTML:
<img src="data:image/png;base64,..." />
For CSS:background-image: url('data:image/png;base64,...');
