Convert Images to Base64
Encoding an image into a Base64 string is incredibly easy. This utility processes your image entirely within your browser, ensuring your files remain secure and are never uploaded to any external servers. Just drag and drop your file to instantly generate the Base64 data, alongside ready-to-use HTML and CSS snippets.
Frequently Asked Questions
How do I convert an image to base64?
Simply drag and drop your image file into the upload zone above. The tool will instantly process your image and output the raw base64 string data, along with ready-to-use HTML and CSS code.
How does the Image to Base64 Encoder work?
Our encoder uses your browser's native FileReader API. Instead of uploading your image to a remote server, the conversion happens entirely locally on your device. This is the fastest and most secure way to process images.
How do I embed a base64 image in HTML?
You can embed it directly into your document using the standard <img> tag with a data URI format in the src attribute. For example: <img src="data:image/png;base64,..." />. Our tool automatically generates this exact HTML string for you.
How to embed base64 image in markdown?
Use the standard markdown image syntax, but replace the file path with your data URI string: . Note that some markdown renderers don't support embedded data URIs, so test in your specific environment first.
How to convert image to base64 python?
In Python, use the built-in base64 module. Open the image in binary mode ('rb') and call base64.b64encode(image_file.read()) to get the encoded string. Decode the result with .decode('utf-8') to get a plain text string you can embed in HTML or CSS.
How to view base64 image or convert back?
If you already have an encoded string and want to view the image it represents, paste the full data URI (e.g., data:image/png;base64,...) directly into your browser's address bar. To decode it back to a file, you can use an atob()-based script in JavaScript or the base64 -d command in a terminal.
When should I use Base64 instead of normal image files?
Base64 is best used for tiny images (like icons, logos, or spinners) to reduce HTTP requests. Because Base64 encoding increases file size by about 33%, it is not recommended for large, high-resolution photographs.
Which image formats does the tool support?
It supports all common web image formats: PNG, JPG/JPEG, GIF, WEBP, SVG, and BMP.
What is the maximum file size for conversion?
To ensure optimal browser performance, the maximum file size allowed for conversion is 5MB.
Can I copy or download the Base64 string after encoding?
Yes! Once the image is processed, you can click the convenient "Copy" buttons next to the Data URI, HTML tag, CSS property, or Raw Base64 string fields.
