About

WebPBox is a simple, fast, and free online tool that converts your images to the modern WebP format. Our goal is to help website owners, developers, and designers optimize their images for better performance without compromising quality.

Why We Created WebPBox

We noticed that many websites still use outdated image formats that slow down page loading times. WebP offers superior compression compared to JPEG and PNG while maintaining excellent quality. With WebPBox, we wanted to create:

A tool that works directly in your browser (no server-side processing)
An interface that's simple enough for anyone to use
Conversion that preserves image transparency when needed
A service that's completely free with no hidden limits

How It Works

WebPBox uses modern browser APIs to process your images locally on your device. This means:

Your images never get uploaded to any server
Conversions happen quickly without internet delays
Your original files remain completely private

Features

Batch conversion: Convert multiple images at once
Quality adjustment: Control the compression level
Transparency support: Preserve alpha channels from PNGs
Fast processing: Typically completes in seconds
No registration: Use it immediately with no signup required
Cross-platform: Works on any device with a modern browser

The WebP Advantage

WebP images are typically:

25-34% smaller than JPEG at equivalent quality
26% smaller than PNG for lossless compression
Supported by all modern browsers
Ideal for websites looking to improve load times
