Why Use This Tool?
Developers and email-template builders need images as base64 strings — for inline CSS, JSON payloads, or self-contained HTML files. Drop an image and get the full data URI instantly, ready to copy.
The tool reads your file locally and never touches a server. A toggle lets you grab the raw base64 without the data: prefix when your framework wants it bare.
How It Works
- Drop your image — PNG, JPG, WebP, GIF, SVG, or ICO all work.
- Toggle the data: prefix on or off depending on where the string is going.
- Hit copy and paste it straight into your code.
Frequently Asked Questions
What's the data: prefix for?
It turns the string into a complete data URI you can paste directly into HTML, CSS, or a browser address bar. Strip it when an API expects raw base64.
Does base64 make files bigger?
Yes — about 33% larger than the binary original. It trades size for convenience, which is perfect for small icons and inline graphics.
Which formats work?
Any file — PNG, JPG, WebP, GIF, SVG, even ICO. The tool encodes the bytes exactly as they are.
How is this a PNG to Base64 converter?
Drop a PNG and the tool encodes the exact bytes into a base64 data URI — no re-encoding, no quality change, ready to copy.
Does it work as a JPG to Base64 converter?
Yes — JPGs encode the same way, and the data URI preserves the image/jpeg MIME type so browsers render it correctly.
Tips & Things to Watch
- Keep inlined images under 10 KB — bigger ones bloat your HTML fast.
- Use the raw output (no prefix) for JSON APIs and Authorization headers.
- SVGs encode to base64 too, handy for email-safe embedded logos.
