Frequently Asked Questions

How do I convert an image to Base64?

Upload your image (JPG, PNG, WebP, GIF — up to 10MB), and we instantly generate its Base64 data URL. Copy it with one click or download it as a .txt file.

What is a Base64 data URL?

A data URL looks like data:image/png;base64,iVBORw0KGgo... — it embeds the entire image as text. Developers use it to inline images directly in CSS, HTML, or JSON APIs without a separate file.

Why use Base64 for images?

Base64 encoding lets you embed small images directly into code, saving HTTP requests. It's also the standard way to pass images through APIs, databases, and JSON payloads.

Is my data secure?

Absolutely. All encoding happens locally in your browser. Your images are never uploaded to our servers, ensuring complete privacy.
