Image to Base64
? Frequently Asked Questions
What is Base64 image encoding?
Base64 converts image binary data to text strings. This allows images to be embedded directly in HTML/CSS (data URIs) or JSON/XML without separate files. Useful for small images, icons, and inline graphics.
When should I use Base64 images?
Use for small images (<10KB) like icons, logos, or inline graphics to reduce HTTP requests. Avoid for large images as Base64 increases size by 33% and can't be cached separately.
How much larger are Base64 images?
Base64 encoding increases file size by approximately 33%. A 30KB image becomes ~40KB. Additionally, Base64 can't be cached by browsers as efficiently as separate image files.
Can I use Base64 images in CSS?
Yes! Use data URIs: background-image: url(data:image/png;base64,iVBORw0K...). This eliminates separate image requests but makes CSS files larger and harder to cache.
What's the recommended size limit?
Keep Base64 images under 10KB for best performance. Larger images should be separate files for better caching, faster initial page loads, and easier CDN delivery.
