Encode an image into a Base64 data URI you can paste directly into HTML or CSS, removing a separate network request — with ready-made <img> and CSS background snippets.
How it works
- Select a small image or icon from your device.
- The browser instantly reads the bytes and converts them into a Base64 string.
- Copy the raw string, or grab the pre-formatted HTML/CSS snippets for immediate use.
Frequently asked questions
When should I actually inline an image as Base64?
It is best practice for extremely small images like UI icons (under ~10 KB). Inlining saves an HTTP request, but larger images bloat your HTML.
Why is the resulting Base64 string bigger than my original file?
The Base64 encoding algorithm inherently adds exactly 33% overhead. You are trading a network request for a slightly larger byte payload.
Is my image uploaded during encoding?
No. The conversion executes entirely via Javascript local FileReader APIs.
