All ToolsFrequently Asked Questions
What is Base64 encoding?
Base64 is a binary-to-text encoding scheme that represents binary data as ASCII characters. It's commonly used to embed images in HTML/CSS or transmit data in URLs and APIs.
Can I encode images to Base64?
Yes. Drag and drop any image file and our tool will convert it to a Base64 data URI string you can embed directly in HTML or CSS.
Is there a size limit?
No server-side limits. Since encoding happens in your browser, the only limit is your device's available memory.
