Frequently Asked Questions

Does resizing decrease image quality?
Downscaling retains sharp details through bilinear canvas interpolation. Upscaling beyond original dimensions may appear soft.
Are my photos uploaded to a server?
No. The image is loaded directly into an HTML5 Canvas element on your local machine. Nothing is transmitted over the internet.
