Base64 FAQ
When should I use Base64 for images?
Base64 is best for small icons, logos, or UI elements (typically under 10KB). Using it for large photos is not recommended as it increases the file size by about 33% compared to the original binary file.
Does it support all image formats?
Yes! Our converter supports PNG, JPEG, WebP, GIF, SVG, and BMP. Any image your browser can display can be converted to Base64.
Is there a size limit?
While we don't impose a hard limit, very large images (e.g., 20MB+) might slow down your browser because the resulting Base64 string will be extremely long.
