How to use / Why use this tool / FAQ
How to use
Drop or click to select any image (JPG, PNG, GIF, WebP, SVG). The Base64 output appears instantly. Choose your output format — Base64 only, Data URL, CSS background, HTML img tag, or Markdown — then copy or download.
Why use this tool
Embed images directly in HTML, CSS, or Markdown without hosting them. Ideal for email templates, inline CSS, single-file documents, and small icons. Everything runs locally — your image never leaves the browser.
FAQ
- What image formats are supported?
- Any image format your browser can read: JPG, PNG, GIF, WebP, SVG, BMP, AVIF, and more.
- Why is the Base64 output larger than the original?
- Base64 encoding increases file size by approximately 33%. This is a trade-off for embedding data directly in text formats.
- Is my image uploaded to a server?
- No. All processing uses the browser's FileReader API — your image never leaves your device.
