Image to Data URL (Base64)

Drop an image, get a base64 data URL back. Preview the picture, see the byte counts, copy what you need. The encoding happens in your browser — the file is never uploaded.

Drop an image here, or click to choose

PNG, JPEG, GIF, WebP, SVG, BMP, ICO, AVIF — up to 10 MiB

How to use this tool

Drop or pick an image file. Supported: PNG, JPEG, GIF, WebP, SVG, BMP, ICO, AVIF. Up to 10 MiB.
Pick an output format: a plain data: URL, a CSS-ready url("…"), or the raw base64 alphabet.
Copy the output, or Download .txt to save it alongside your source.
Files are encoded with FileReader.readAsDataURL. The page never makes a network request for your image.
Right-click the preview to save the original — the data URL is just an encoding, not a transform.
