Frequently Asked Questions
What is Base64 encoding for images?
Base64 encoding converts binary image data into a text string (data URL). This lets you embed images directly into HTML, CSS, or JSON without needing a separate file.
How do I use the Base64 string in HTML?
Use it as the src attribute: <img src="data:image/png;base64,YOUR_STRING_HERE" />. The full data URL output from this tool is ready to paste.
Does the file size increase after Base64 encoding?
Yes. Base64 encoding increases the data size by approximately 33% compared to the original binary file.
Are there any file size limits?
Very large images may produce extremely long strings. For practical use in HTML or CSS, keep images under 100KB before encoding.
Is my image uploaded to a server?
No. Everything happens in your browser. Your image is read locally using the FileReader API and never sent to any server.
