WHAT IS BASE64?
Base64 encodes binary image data as a plain text string. Instead of linking to a separate image file, you embed the image directly in your HTML, CSS, or source code as a data URI.
WHY USE THIS?
Embedding images as Base64 eliminates extra HTTP requests, making pages load faster for small assets. It's essential for:
▸ Email templates that need self-contained images
▸ Single-file HTML apps, demos, and prototypes
▸ CSS backgrounds without external file dependencies
▸ Storing thumbnails or icons in JSON, databases, or config files
▸ Embedding assets in browser extensions or bookmarklets
▸ Anywhere you need a fully portable, zero-dependency image
HOW IT WORKS
Drop an image into the workspace. Crop, adjust, and set your output resolution and quality. The Base64 string updates live in the clipboard panel — then, copy the output you need.
🔒 100% CLIENT-SIDE — your image never leaves your browser. No uploads, no servers, no tracking.
TIPS
Base64 adds ~33% overhead vs binary. Keep images small — icons, thumbnails, and UI elements work best. For photos larger than ~50KB, a regular image file is usually more efficient.
