How to use the Image to Base64 Encoder
Drag and drop one or more image files onto the upload area, or click it to open your file browser
Click any file in the list to select it and view its Base64 output, preview, and size statistics
Choose an output format from Data URI, HTML, CSS, Markdown, or JSON to get a snippet ready to paste into your code
The stats strip shows your original file size, the resulting Base64 size, and the percentage increase from encoding
Switch to the Preview tab to confirm the image renders correctly directly from its Base64 data URI
Click Copy to copy the generated snippet to your clipboard, or Download to save it as a text file
Check the When to Use tab for guidance on when Base64 encoding helps and when a regular image file is the better choice
Base64 encoding increases file size by roughly 33 percent, so it is best suited for small images like icons and logos
All encoding happens locally using the FileReader API. Your images are never uploaded to any server
Use Clear All to remove every file and start fresh, or remove individual files using the Remove button on each row
