FAQ
Can I upscale an image?
Yes, the percentage slider goes up to 500%, though enlarging beyond the original resolution will soften detail.
Are my images uploaded?
No. Resizing happens locally with the browser canvas, nothing leaves your device.
Can I resize by percentage?
Yes, enter a percentage or specific pixel dimensions. Aspect ratio is locked by default to prevent distortion.
Will resizing reduce quality?
Downscaling is lossless for practical purposes. Upscaling adds no new detail, the image is interpolated.
