Base64 encoding increases file size by approximately 33% due to the encoding overhead. Use for small images or when embedding is necessary.
Use Base64 for small icons, logos, or when you need to embed images directly in CSS, HTML, or JSON without external file references.
No! All conversion happens in your browser using JavaScript. Your image never leaves your device.
