Image to Base64 & Base64 to Image

Image to Base64 is a lightweight Chrome extension for anyone who needs image to base64 fast, clean, and fully offline. Drop a file, get a ready string, and keep your data on your device while you convert image to base64 in one click. It runs with minimal permissions (storage, clipboard, downloads) and makes zero network requests—your images never leave your browser.

When you work with web layouts, emails, docs, or APIs, sometimes you need a base64 picture instead of a file attachment. Image to Base64 helps you generate a compact picture, prepare image base64 output for documentation, and do png to base64 for icons, screenshots, and UI assets. This is also handy when you ship base64 images inside JSON, embed them in Markdown, or store a small base64 of image as a placeholder.
