画像からBase64 の使い方
Drag and drop or select an image file (PNG, JPEG, SVG, GIF, WebP). The tool reads the file locally and converts it to a Base64-encoded data URI string. Copy the full data URI for embedding directly in HTML img tags or CSS background-image properties. File size and format details are displayed automatically.

よくある質問
Is my image uploaded to a server?+
No. The conversion happens entirely in your browser using the JavaScript FileReader API. Your image never leaves your device.
Is there a file size limit?+
There's no hard limit, but Base64 encoding increases size by ~33%. Converting large images (over 100KB) to Base64 is generally not recommended as it bloats your HTML/CSS and hurts performance.
