Base64 Image Encoder

Convert images to Base64 data URIs for inline embedding — and preview Base64 back as image.

About the Base64 Image Encoder

The Base64 Image Encoder converts an image file into a data URI you can embed directly in HTML or CSS — no extra HTTP request. Paste a data URI the other way to preview it. Everything stays in your browser.

Only for small assets (icons under ~5 KB) — Base64 adds ~33% size and cannot be cached separately.
