Convert images to Base64 data URIs and decode Base64 strings back to images instantly in your browser.
The Base64 Image Converter is a privacy-first utility that transforms images into Base64 data URIs and decodes Base64 strings back into downloadable images. It supports JPEG, PNG, WebP, GIF, and SVG formats, and runs entirely in your browser with zero server uploads.
Choose between Image to Base64 or Base64 to Image modes. For encoding, drag and drop or click to upload an image file. The tool instantly generates the full data URI and the raw Base64 string. For decoding, paste a Base64 string or data URI and click Decode to preview and download the resulting image.
Embedding images as Base64 data URIs is common for emails, CSS backgrounds, and small inline assets. Doing this locally ensures your images are never exposed to third-party servers, which is critical for confidential screenshots or proprietary graphics.
