Frequently asked questions
Are my photos uploaded to a cloud server?
No. Compression runs 100% in your local browser RAM using HTML5 Canvas API. Your images never leave your device and are not stored anywhere.
What quality level should I use?
80-85% quality for JPEG/WebP gives near-identical visual quality to the original while reducing file size by 50-70%. Below 60% quality produces visible compression artifacts.
Why is WebP better than JPEG?
WebP uses advanced predictive coding and supports both lossy and lossless compression. At the same visual quality, WebP files are typically 25-35% smaller than JPEG.
