Image ↔ Base64

Convert images to Base64 data URIs for embedding in HTML, CSS, or code — and decode Base64 strings back to viewable images. Supports PNG, JPEG, GIF, WebP, SVG, and all common image formats. Works entirely in your browser with no uploads.

Why choose Image ↔ Base64?

Image ↔ Base64 provides a fast, client-side solution for converting images into data URIs for direct embedding in code, CSS, or HTML, as well as decoding Base64 strings back into viewable image files. Because processing happens entirely within your browser without file uploads, it ensures both privacy and immediate conversion speed for common formats like PNG, JPEG, GIF, WebP, and SVG.

Good to know: Very large image files may generate extremely long Base64 strings that can bloat source code if not handled carefully.
