| PNG | Lossless | ✅ | Screenshots, logos, icons |
| WebP | Lossy + Lossless | ✅ | Web images — best size/quality |
Why WebP?
WebP typically achieves 25–35% smaller file sizes than JPEG at equivalent visual quality, and 26% smaller than PNG. All modern browsers support WebP. It's the recommended format for web images in 2025.
Frequently Asked Questions
Are my images uploaded to a server?
No. Conversion happens 100% in your browser using the HTML5 Canvas API. Your images never leave your device — no upload, no server processing, no storage.
Why can't I convert to PNG with quality control?
PNG uses lossless compression — every pixel is preserved exactly. The quality slider only applies to JPEG and WebP which use lossy compression where you trade some quality for smaller file size.
Can I convert animated GIFs?
The Canvas API extracts only the first frame of animated GIFs. For full animated GIF conversion you'd need a server-side tool (like FFmpeg). This tool is best for static images.
