What is Base64 encoding for images?

Base64 encoding converts binary image data into ASCII text characters. This allows images to be embedded directly in HTML, CSS, or JavaScript code as data URIs, eliminating the need for separate image file requests.

Will the Base64 output work in all browsers?

Yes, Base64 data URIs are supported by all modern browsers including Chrome, Firefox, Safari, and Edge. The AVIF format itself may have varying support, but the Base64 string will work wherever AVIF is supported.

Why is the Base64 string larger than the original file?

Base64 encoding increases file size by approximately 33% because it converts binary data to ASCII text. This trade-off is acceptable for small images where reducing HTTP requests is more valuable than the size increase.

Can I use the Base64 output directly in my code?

Yes, the output includes the complete data URI format (data:image/avif;base64,...) that you can paste directly into HTML img src attributes, CSS background-image properties, or JavaScript code.

Is there a file size limit for conversion?

Our tool supports AVIF files up to 50MB. However, for practical use, Base64 encoding is most beneficial for smaller images under 100KB to avoid bloating your HTML or CSS files.

Are my images secure when using this converter?

Absolutely. All image processing happens locally in your browser. Your AVIF files never leave your device or get uploaded to any server, ensuring complete privacy and security.
