Image to Base64

Key features

• Encodes any image into a complete data:image/...;base64 string instantly via FileReader.
• Copy as the raw data URL or as a ready-to-paste CSS background-image rule.
• Stat tiles show the original size, Base64 character count and the encoding overhead.
• A 'rendered proof' image whose source is the generated string confirms the encoding is valid.
• Everything happens locally — no network request is involved at any point.

How it works

1. 1

   Drop A Small Asset

   Icons and logos under roughly 200 KB are the ideal use case.

2. 2

   Read The Stats

   The tiles show how much weight the encoding adds compared to the original file.

3. 3

   Copy What You Need

   Grab the plain data URL or the formatted CSS rule with one click.

4. 4

   Paste Into Your Code

   Use it in an img src, a CSS background, or a single-file HTML document.

Tips for better results

• 💡Base64 inflates files by about a third — the overhead tile shows the exact figure, so embed only small assets.
• 💡Data URLs eliminate one network request and keep working offline inside a single HTML file.
• 💡For large hero images, stick to normal files; embedding them bloats your HTML or CSS.
