About Image Tools
Image Tools handle the most common photo and graphic chores: compressing files without obvious quality loss, converting between JPG, PNG, and WebP, resizing to exact dimensions or by percentage, and cropping with preset aspect ratios. Every operation uses the browser's Canvas API and runs entirely on your machine — your photos never leave your device, even for a moment.
For compression we use the same Web Worker-backed pipeline behind many open-source image apps, so a five-megabyte photo typically processes in under two seconds. The format converters preserve alpha where the target supports it, and the crop tool offers free or fixed aspect modes for square posts, landscape video, and portrait thumbnails.
Frequently asked questions
Are my images really not uploaded?+
Confirmed in DevTools: there are no network calls during compression, conversion, resize, or crop. The browser's Canvas API and a small worker handle everything locally.
Why does PNG to JPG ask me for a background color?+
JPG does not support transparency. We need a solid color to fill anywhere the PNG was transparent; white is the safe default.
Will WebP work in every browser?+
Modern Chrome, Edge, Firefox, and Safari 14+ all decode WebP. Older Safari can encode WebP only since 16, so the WebP Converter warns you if encoding is unavailable.
