What is Base64 Image Encoding?
Base64 is an encoding scheme that converts binary data (like images) into an ASCII string format. Our Image to Base64 tool allows you to convert any image file into a text string that can be easily embedded directly into code.
When to use Base64 Images
- Inline HTML/CSS: Embed small icons or backgrounds directly into HTML (`<img src="data:image/png;base64,...">`) or CSS (`background-image: url(...)`) to reduce HTTP requests.
- JSON Payloads: Send image data through APIs that only accept text formats.
- Database Storage: Store small images directly in text-based database fields when a separate file storage system isn't practical.
Important Considerations
Are Base64 strings larger than the original image?
Yes, Base64 encoding typically increases the file size by about 33% compared to the original binary image. It is best used for small icons, logos, or placeholders rather than large photographs.
