Frequently Asked Questions

What is Base64?

Base64 is a way to encode binary data (like images) into a text string using only ASCII characters. It's commonly used to embed images directly into HTML, CSS, or JSON files.

How do I use this tool?

Click the "Select Images" button, choose one or more images from your device, and the tool will instantly convert them to Base64. You can copy the Base64 string using the "Copy" button.

Is my image data safe?

Yes! All conversions are done in your browser. Your images are never uploaded to any server and remain private on your device.

Where can I use Base64 images?

You can use Base64 images in HTML <img> tags, CSS background-image properties, or anywhere you need to embed image data as text.

Are there size limits?

There is no strict limit, but very large images will produce long Base64 strings and may slow down your browser. For best results, use images under 2MB.
