What is Base64 Encoding?
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used when you need to embed image data directly in HTML, CSS, or JSON files.
Converting an image to Base64 allows you to:
- Embed images directly in your HTML or CSS without external image files
- Reduce HTTP requests, potentially improving page load times
- Include image data in JSON payloads or API responses
- Store image data in databases that don't support binary data
Our free Image to Base64 converter processes your image entirely in your browser - your files are never uploaded to our servers, ensuring complete privacy and security.

Frequently Asked Questions
What is the maximum file size for conversion?
There's no strict limit since all processing happens in your browser. However, very large images (over 5MB) may result in long Base64 strings that could cause performance issues in some applications.
Is my image data secure?
Yes, all processing happens locally in your browser. Your image is never uploaded to our servers, ensuring complete privacy and security.
What image formats are supported?
This tool supports most common image formats including JPG, PNG, GIF, BMP, and WEBP.
Will Base64 encoding increase the file size?
Yes, Base64 encoding typically increases the file size by approximately 33% compared to the original binary data. This is because Base64 uses 8 bits to represent 6 bits of data.
When should I use Base64 encoded images?
Base64 encoding is useful for small images that need to be embedded directly in HTML, CSS, or JSON. It reduces HTTP requests but increases the overall file size. For larger images, traditional image files served via URLs are usually more efficient.
