Frequently Asked Questions
Are my private photos uploaded to a cloud server?
No. The entire compression process takes place within your computer GPU/CPU via the HTML5 canvas toBlob API. Your images never leave your browser.
Which format gives the smallest file size?
WebP typically provides 25% to 35% better compression than JPEG at equivalent visual quality.
