How to use the Image to Base64 converter

  1. Upload or paste your image — Drag & drop an image file onto the upload area, click to browse your files, or simply paste from your clipboard with Ctrl+V.
  2. Choose output format — Select JPEG, PNG, WebP, or keep the Original format. Adjust the quality slider for lossy formats (JPEG/WebP) if needed.
  3. Copy the Base64 code — Click the Copy to Clipboard button and paste the data URI directly into your HTML, CSS, or any text file.

Base64 encoding converts binary image data into a plain text string that can be embedded directly in HTML and CSS using data URIs. This eliminates the need for separate image files, reduces HTTP requests, and is ideal for small icons, email templates, and offline-first web applications.
