Frequently asked questions
What is Base64 encoding?
Base64 encoding converts binary data (like an image) into a text string of ASCII characters. This allows images to be embedded directly into HTML or CSS files.
Why should I convert an image to Base64?
Embedding small images as Base64 strings in your code reduces HTTP requests, which can speed up page load times for small icons or logos.
Is my image sent to a server for conversion?
No, the conversion to Base64 happens instantly in your browser. Your images are never uploaded.
What formats can be converted to Base64?
You can convert JPG, PNG, WebP, GIF, and SVG images to Base64 data URIs.
Can I copy the Base64 code for HTML or CSS?
Yes, the tool provides formatted strings ready to be pasted into an HTML <img> tag or as a CSS background-image.
Is there a size limit for images?
While there is no hard limit, we recommend only encoding small images (under 100KB), as large Base64 strings can bloat your HTML/CSS files.
Does Base64 encoding compress the image?
No, Base64 encoding actually increases the file size by about 33% compared to the original binary file.
Can I decode Base64 back into an image?
This tool is an encoder, but many online tools allow you to paste a Base64 string and decode it back into an image file.
