Why should I convert images to WebP format?

WebP provides superior lossless and lossy compression for web images, typically achieving **25-35% smaller file sizes** compared to JPEG and PNG at equivalent visual quality, improving Core Web Vitals (LCP).

Are my photos uploaded to any external server?

No. All image decoding, rendering, and encoding happens entirely in your browser's HTML5 Canvas memory. Your files never leave your device.

Can I convert SVG vector files to PNG or WebP raster images?

Yes! Drop any `.svg` vector file into the converter and select PNG or WebP with your desired resolution scale to generate crisp raster bitmaps.
