Frequently asked questions
How do I keep the aspect ratio?
Calculate proportionally: if a 2000×1000 image should be 800 wide, set height to 400 (same 2:1 ratio) to avoid stretching.
Will enlarging a small image improve it?
No — upscaling cannot add detail and usually looks blurry. Resizing works best when going down in size.
What formats are supported?
JPG and PNG work best; the output is generated through the browser canvas, preserving broad compatibility.
