Frequently Asked Questions

Base64 converts binary image data into a text string that can be embedded directly in HTML, CSS, or JSON files — eliminating an additional HTTP request.

Use Base64 for small images like icons and logos where the overhead of an HTTP request outweighs the base64 size increase (~33%). Avoid it for large photos.

Use it as the src attribute: <img src="data:image/png;base64,YOUR_BASE64_STRING" />. Our tool provides the complete ready-to-use data URL.

About This Tool

Base64 encoding converts binary image data into a plain-text ASCII string that can be embedded directly inside HTML, CSS, JSON, or XML files — eliminating the need for a separate HTTP request to fetch an external image file. This is particularly useful for embedding small icons, logos, and UI elements in single-file HTML emails (which often block external image requests), inline SVG files, CSS background-image properties, and REST API payloads that need to carry image data without multipart form encoding. PixlTools converts your image server-side to a complete, ready-to-use data URL in the format `data:image/jpeg;base64,...`. The output can be pasted directly into an `<img src>` attribute, a CSS `url()` value, or a JSON string field. For images larger than 10–20KB, Base64 inflates file size by ~33%, so this format is best reserved for small assets.
