Encode any image as a Base64 data URI string for embedding directly in HTML, CSS, or JavaScript. No external file hosting needed.
Supports JPG, PNG, SVG, GIF, WebP, BMP, ICO and more
Files are processed locally in your browser. Nothing is uploaded to a server.
The image to Base64 converter encodes image files as Base64 text strings that you can embed directly in HTML, CSS, or JavaScript code. This eliminates the need for separate image file hosting — the image data lives right inside your code.
Upload any image and get a ready-to-use data URI string. The tool supports convert image to Base64 from JPG, PNG, SVG, GIF, WebP, BMP, and ICO. You can also convert Base64 to image — paste a Base64 string and download the decoded image file.
Base64 encoding converts binary data into ASCII text using 64 characters (A-Z, a-z, 0-9, +, /). The resulting string is about 33% larger than the original file, so this is best for small images like icons, sprites, and tiny graphics — not large photographs.
Getting Started
Drag and drop your file into the converter, or click to browse. Supports JPG, PNG, SVG, GIF, WebP and more.
Configure output settings like quality, size, and format options. Defaults work well for most use cases.
Click "Convert" and your Base64 file is ready in seconds. Free, unlimited, no account required.
Web developers embed tiny images (icons, logos, sprites) as Base64 to reduce HTTP requests and improve page load speed. Email developers use Base64 to inline images in HTML emails. CSS developers embed background images as data URIs.

Paste a Base64 string into the decoder field and the tool converts it back to a downloadable image file.
No. Base64 increases file size by about 33%. Use it for small images under 10KB. For larger images, serve them as regular files.
