Key Formulas

The tool uses these image processing techniques:

canvas.width = image.naturalWidth

canvas.height = image.naturalHeight

quality = qualitySlider.value / 100

webpData = canvas.toDataURL('image/webp', quality)

savings = ((originalSize - webpSize) / originalSize * 100).toFixed(1) + '%'

Performance Optimization

Frequently Asked Questions

Is WEBP better than JPG?

WEBP typically offers 25-35% smaller file sizes than JPG at equivalent quality, with better compression algorithms.

What quality setting should I use?

80-85% quality typically provides excellent results with significant file size reduction. For critical images, use 90-100%.

When should I use lossless compression?

Use lossless for images that must be pixel-perfect (logos, graphics), and lossy for photos where small quality loss is acceptable.

Do all browsers support WEBP?

All modern browsers support WEBP. For legacy browsers (IE11), you should provide JPG fallbacks.

What's the maximum image size supported?

The tool handles most images, but very large files (50+ MB) may cause browser performance issues.

Can I convert multiple files at once?

Current version processes one file at a time for best quality control.
