Use the Image to Base64 in three steps
Choose an image
Open any image format supported by your browser.
Let the browser encode it
The complete data URL appears as soon as the file is read.
Copy or save
Paste the value into code or download it for later use.
When Base64 is useful
Embedding a small asset can remove a separate file request and makes a snippet self-contained. It is most useful for small, stable images rather than large photos.
The size tradeoff
Base64 text is typically about one-third larger than the original binary data. Large embedded images can make HTML, CSS, or JSON harder to cache and maintain.
Image to Base64 FAQ
What is a data URL?＋
It is a string that contains both the image type and its Base64-encoded content, beginning with data:image/.
Can I paste the result into an img tag?＋
Yes. Use the complete data URL as the value of the src attribute.
Is Base64 encryption?＋
No. Base64 is an encoding format and can be decoded by anyone who has the text.
Why is the output longer than expected?＋
Binary data expands when represented with Base64 characters, and the data URL also includes a short MIME-type prefix.
Which image formats work?＋
Any format your browser can read as a file can be encoded, including common PNG, JPG, WebP, GIF, and SVG images.
Does the tool reduce image quality?＋
No. It encodes the original file bytes without resizing or recompressing the image.
