Frequently asked questions
Which fit should I pick?
"Crop to fill" keeps proportions and trims the excess; "fit" adds borders; "stretch" distorts to fill exactly.
Does upscaling add detail?
No: enlarging interpolates pixels. Real sharpening needs the future AI upscale tool.
Which formats are accepted?
JPG, PNG, WEBP, AVIF, BMP and GIF (first frame). The output keeps the original format when possible.
Is my image uploaded to a server?
No. All processing happens on your device using the browser itself; the image never leaves it.
