Data URL Generator

Encode text or files into data: URIs (with MIME, charset, base64) and decode them back. Live previews for images/HTML/SVG/JSON, copyable snippets, QR generation, batch decode, and optional minify/sanitize — all local.

Tip: For sharing small snippets (≤ ~2.8k chars), QR works well. Larger images/HTML may exceed capacity.
