What is Image to Base64 Encoder?

Image to Base64 Encoder converts image files (PNG, JPEG, GIF, SVG, WebP) into Base64-encoded text strings. Embed images directly in HTML, CSS, or JSON without hosting separate files — fewer HTTP requests, simpler markup.

How to use

  1. Step 1 — Upload an image file by dragging and dropping it or clicking the upload area. Supported formats include PNG, JPEG, GIF, SVG, and WebP.
  2. Step 2 — Pick an output format: raw Base64, data URI (with MIME type prefix), or HTML img tag embed code.
  3. Step 3 — Copy the result to your clipboard or download it as a text file.

Result

You have a 2KB logo icon that you want to embed directly in an email template. Upload the PNG file, copy the data URI output, and paste it into your HTML img src attribute — no external hosting needed.
