// How it works

Three steps. Zero uploads.

01
Drop
Drag your image onto the page. JPG, PNG, WebP, GIF, SVG, and BMP are supported. It stays on your device.
02
Encode
fwip reads the file and converts it to Base64 in your browser. Choose data URL or raw string format.
03
Copy
Click to copy the Base64 output. Nothing was ever uploaded.
// Why this is different

Your image never leaves your machine.

Most online Base64 encoders upload your image to a server, encode it there, and send back the result. Your file passes through systems you don't control.

fwip works differently. The encoding engine runs entirely in your browser. Your image is read from your device, processed on your CPU, and the result is saved back to your device. No server is involved. We literally cannot see your file.

No server processing

Everything runs on your device using WebAssembly. Your file never touches a network.

No account required

Drop a file. Get a result. No sign-up, no email, no password.

No subscription

Free in the browser. $99 once for the offline bundle. That's it. Forever.

Works offline

The desktop version works with no internet connection at all.

// Questions

Frequently asked.

How do I convert an image to Base64 without uploading?▾
Drop your image into fwip. It converts to a Base64 data URL or raw string entirely in your browser. Your image never leaves your device.
What image formats can I convert to Base64?▾
fwip supports JPG, PNG, WebP, GIF, SVG, and BMP. The output includes the correct MIME type in the data URL.
Can I use the Base64 string in HTML or CSS?▾
Yes. fwip outputs both a data URL (ready for img src or CSS background) and the raw Base64 string. Click to copy either format.
