Why Use WebP?
WebP images are typically 25–35% smaller than equivalent JPEGs and 26% smaller than PNGs at the same perceptual quality. Switching to WebP is one of the fastest wins for website load-time performance and Core Web Vitals scores.
How It Works
The browser draws your image to a canvas and calls canvas.toBlob('image/webp', quality) — a completely native API available in all modern browsers. No external library or server is needed.
Key Features
- Quality slider (1–100) with live estimated output file size
- Lossless mode toggle
- Side-by-side file size comparison: original vs WebP
- Batch conversion — drop multiple files at once
- Download individually or all as a ZIP archive
- Supports PNG, JPG, GIF, BMP, and WebP input
