Data URL output
Base64 data URL will appear here.
Base64 makes images larger than the original file. Use it for small assets, email snippets, prototypes, or API inspection rather than large production images.
How to use Image to Base64
- Choose a PNG, JPG, WebP, GIF, or SVG image file from your device.
- Review the local preview, MIME type, file size, and generated Base64 length.
- Copy the full data URL when you need the MIME prefix, or copy the raw Base64 payload when another system already expects the image type.
Examples
Copy patterns and edge cases worth checking.
Copy raw Base64
Some APIs ask for only the Base64 payload, without the data:image/... prefix.

FAQ
Short answers before you paste real data.
Are selected images uploaded?
No. The file is read with browser APIs and converted locally in your current browser session.
Why is the Base64 output larger than the image file?
Base64 represents binary bytes as text, which usually makes the output roughly one third larger than the original file.
Should I convert large images to Base64?
Usually no. Base64 is best for small assets and inspection. Large data URLs can make pages heavy and harder to cache.
