Frequently Asked Questions

How does image compression work?▼

Image compression reduces file size by removing unnecessary data. Lossy compression (JPEG) discards some visual detail, while lossless compression (PNG) uses efficient encoding without quality loss.

Will compression reduce my image quality?▼

At 80-90% quality, compression is virtually imperceptible to the human eye while significantly reducing file size. Lower quality settings produce smaller files with noticeable artifacts.

Is my image uploaded to a server?▼

No - compression happens entirely in your browser using Canvas API. Your images never leave your device.
