Compress Image FAQ
Which image formats can I compress with this tool?
You can compress JPG, JPEG, PNG, and WebP files with instant before-and-after size comparison and quality previews.
How much file size reduction can I expect?
Most photos achieve 50% to 80% reduction with virtually imperceptible visual difference, making them ideal for web pages and email.
Are my compressed photos stored on any remote server?
No. Image compression executes on your device's canvas and WebAssembly runtime. Your photos never leave your device.
Can I compress PNG images with transparent backgrounds?
Yes. PNG compression preserves alpha transparency channels perfectly while optimizing color palettes to decrease file size.
