Frequently Asked Questions

What is Base64 image encoding?
Base64 encoding converts binary image data into a text string that can be embedded directly in HTML, CSS, or other text-based formats. This eliminates the need for separate image files.
When should I use Base64 encoded images?
Use Base64 encoding for small images (under 10KB), icons, logos, or when you need to create self-contained files. Avoid it for large images as it increases file size by about 33%.
What image formats are supported?
All common web image formats are supported: PNG, JPG/JPEG, GIF, SVG, WebP, BMP, and ICO. The original format is preserved in the encoded output.
Does Base64 encoding affect image quality?
No, Base64 encoding is lossless. The image quality remains exactly the same. However, the file size increases by approximately 33% due to the encoding overhead.
Are there file size limits?
While there's no hard limit, we recommend keeping images under 100KB for performance. Large Base64 strings can slow down page loading and increase memory usage.
Can I use Base64 images in all browsers?
Yes, data URIs are supported in all modern browsers and most email clients. Very old browsers (IE7 and below) have limited support.
