Free tool No accountImage to Base64
Turn an image into a Base64 data URL for HTML, CSS or JSON — locally, nothing uploaded.
About the Image to Base64
Turn an image into a Base64 data URL you can put straight into HTML, CSS or JSON, without a separate file.
How to use it
- Drop or choose an image.
- Copy the data URL, the Base64 only, an <img> tag or a CSS line.
- Paste it into your code.
Tip: Keep it for small images (icons, logos under ~10 KB); large pictures are better as normal files.
Questions
Is my data uploaded?
No. The tool runs in your browser; what you paste or open never leaves your device and nothing is stored on a server.
