How to use this tool
Embed Assets Offline
Base64 strings represent binary image data as ASCII text. You can embed these strings directly inside HTML document tags or CSS stylesheets to render graphics without sending HTTP image requests.
Encoding and Decoding
Input files or data payloads to convert styles.
Select Action Mode
Use the top tabs to choose Encode Image (converts files to text) or Decode String (converts text to image files).
Drop File / Paste Code
For encoding, drop your PNG/JPG/SVG. For decoding, paste your base64 text payload or standard DataURL string.
Copy / Download
Copy the HTML <img> tag, copy raw base64 data, or download the decoded image file to your device.

What are the benefits of base64 images?
Converting images to base64 allows you to package complete layouts, logos, or icons in a single HTML, XML, or CSS file. This eliminates network file requests, rendering the page layout faster.
What are the drawbacks of base64?
Base64 strings are approximately 33% larger in data weight than raw binary image files. Avoid base64 encoding very large photos, as it increases your CSS/HTML bundle size, increasing rendering latency.
