Why Convert Images to Base64?

Base64 encoding changes image data into plain text, which makes it easy to put images directly into code and data formats. This is especially useful for:

• HTML & CSS embedding (e.g., inline images or CSS background images)
• JavaScript projects that bundle assets into a single payload
• Email templates where you want to insert an image as inline data
• APIs & JSON workflows that accept Base64-encoded media

Tip: Base64 can make your image data bigger. It's usually better for small things like icons and logos than for big photos.

FAQ

Is Base64 a better way to store images than a regular file?

It depends. Base64 can be useful for small files and single-file deployments, but it can make payloads bigger and caching less useful. For most big pictures, serving normal files is usually the best option.

What can I use Base64 images for?

Some common uses are inline icons, small logos, email templates, API payloads, and putting images in HTML/CSS/JS when hosting them on a separate server isn't possible.

How do I copy the Base64 output on ToolLoom?

After selecting an image, use the Copy to Clipboard button in the Base64 Output area.
