Frequently Asked Questions

What is Base64 encoding?

Base64 is a way to represent binary data (like images) as ASCII text. It's commonly used to embed images directly into HTML or CSS without separate file downloads.

Why would I convert an image to Base64?

Embedding images as Base64 eliminates HTTP requests for small images, improving page load speed. It's great for icons, logos, and email templates.

Is my image uploaded to a server?

No. All encoding happens locally in your browser using the FileReader API. Your images never leave your device.

What image formats are supported?

JPG, PNG, WebP, GIF, and SVG are all supported. The Base64 string will include the correct MIME type prefix.

Is there a file size limit?

Free users can convert images up to 2MB. Pro users get unlimited file sizes.
