Frequently Asked Questions
What is Base64 image encoding?
Base64 encoding converts binary image data into a text string using 64 ASCII characters. This allows images to be embedded directly in HTML, CSS, or JSON without separate file requests.
What image formats are supported?
This tool supports JPG, PNG, GIF, WebP, and SVG formats. The maximum file size is 10MB.
What is a data URI?
A data URI is a scheme that embeds data directly in web pages using the format: data:image/png;base64,... You can toggle whether to include this prefix in the output.
How do I use Base64 images in HTML?
Use the data URI format in the src attribute: <img src="data:image/png;base64,YOUR_BASE64_STRING" />. This embeds the image directly without external file references.
Can I decode Base64 strings back to images?
Yes! Switch to "Base64 to Image" mode, paste your Base64 string, and click "Decode to Image" to preview and download the original image.
Why use Base64 encoding for images?
Base64 encoding is useful for embedding small images in CSS/HTML to reduce HTTP requests, transferring images via JSON APIs, storing images in databases, or bypassing CORS restrictions.
