Image to Base64 Converter

Binary files are dense; Base64 encodes every three bytes as four ASCII characters (~33% overhead) plus the `data:image/...;base64,` prefix for URLs. That inflation matters when you embed multi-megabyte photos—small icons are fine, hero images are not.

Processing is local, but anything you embed in public HTML or JavaScript becomes visible to every visitor and scraper. Treat Base64 in pages like any other secret: if it should stay private, keep it on the server and serve binary via authenticated routes.

It reflects what the browser knows about the `File` object—typically `image/png`, `image/jpeg`, or `image/webp`. If an OS mislabels a rare type, downstream consumers might mis-parse; re-export through a known format when integrating with picky parsers.

Yes: focus the dashed zone and press Ctrl/Cmd+V when Slack, Figma exports, or snipping tools place an image on the clipboard. Some mobile browsers restrict clipboard image writes—use browse as fallback.

Very large images produce strings that choke textarea rendering, DevTools copy, or backend JSON parsers with default limits. Prefer assets under a few hundred KB for inline patterns; otherwise use a CDN URL.

This page is optimized for files: you get both the full `data:` URL and the naked Base64 block, with MIME included automatically. The general encoder targets arbitrary UTF-8 strings, not raster decode guarantees.
