Frequently Asked Questions
Will compressing reduce image quality?▾
Slightly, but often imperceptibly. At 80% quality, JPEG images look virtually identical to the original while being 60-80% smaller. WebP format achieves even better compression at the same quality level.
Which format should I use?▾
WebP offers the best size-to-quality ratio and is supported by all modern browsers. Use JPEG for photos if you need maximum compatibility. Use PNG only when you need transparency.
Are my images uploaded anywhere?▾
No. All compression happens in your browser using the HTML5 Canvas API. Your images never leave your device — you can even use this tool offline.
