FAQ
Why convert image to Base64?
Converting images to Base64 allows you to embed them directly into HTML or CSS files, reducing the number of HTTP requests and speeding up page load times for small images.
Is there a file size limit?
Since processing is done in your browser, the limit depends on your device's memory. However, it's recommended to use Base64 only for small images (icons, logos) to avoid bloating your HTML file size.
Does quality loss occur?
No, Base64 encoding is lossless. The decoded image will be identical to the original.
