Frequently Asked Questions
Getting Started
What is a Base64 data URI?
A Base64 data URI is a string that encodes the image data directly into the HTML or CSS, eliminating the need for a separate HTTP request. It starts with data:image/png;base64,...
Is this tool free?
Yes. All tools are completely free and run locally in your browser.
Usage Tips
When should I use image to Base64?
Base64 encoding is useful for small images like icons or sprites that you want to embed directly in CSS or HTML to reduce HTTP requests. For larger images, standard file linking is more efficient.
What image formats are supported?
PNG, JPEG, GIF, SVG, and WebP formats are supported. The tool detects the format automatically and generates the correct MIME type in the data URI.
Base64 to Image
How do I convert Base64 back to an image?
Paste a Base64 data URI (starting with data:image/...) into the "Base64 to Image" section and click "Render Image". The tool will decode and display the image, and you can download it as a file.
What is a data URI?
A data URI is a string that embeds file data directly into HTML or CSS using the format data:[mime type];base64,[data]. It eliminates the need for a separate HTTP request for the file.
Can I use raw Base64 without the data: prefix?
Yes. The tool automatically detects if your input is a full data URI (data:image/png;base64,...) or just the raw Base64 string. In both cases, it will decode and display the image correctly.
Is Base64 to Image conversion also private?
Yes. All Base64 decoding is done entirely in your browser. No data is sent to any server, ensuring complete privacy for your images and encoded data.
