Frequently asked questions
Will resizing reduce quality?
Downscaling uses the browser's high-quality resampling; upscaling will soften the image as expected.
Can I lock the aspect ratio?
Yes — by default width and height stay proportional; you can unlock them for free resizing.
Is my image uploaded?
No. Resizing happens entirely in your browser.
