## About

Image to Base64 & Base64 to Image is a lightweight Chrome extension that converts both directions:
- Encode: turn an image (PNG, JPG, GIF, WebP, HEIC, SVG) into a Base64 / data URI string.
- Decode: paste a Base64 string or data URI and get a real image back (PNG, JPG, GIF, WebP, SVG, BMP, ICO).

The output format on decode is detected automatically (from the data URI MIME type or the byte signature), with a manual override. All processing happens locally in the browser — no file is ever uploaded to any server.

## Key Features

- Two-way conversion: image to base64 and base64 to image in one tool
- 100% offline, zero network requests — your files never leave the browser
- SVG support on both sides; automatic format detection when decoding
- Output presets: Data URI, Raw Base64, HTML img, CSS url(), Markdown, JSON string, URL-safe Base64
- Local history with thumbnails for both directions
- Drag & drop or paste; one-click copy and download
- Supports images up to 10 MB

## Use Cases

- Embedding images directly in HTML, CSS, JSON or Markdown as a data URI (no external file/hosting)
- Recovering an image from a Base64 string or data URI
- Preparing inline images for emails, documentation or APIs
- Quick offline encoding/decoding without uploading sensitive images to an online tool
