Frequently Asked Questions
Can I resize to any dimension?
Yes, enter any width and height in pixels. There are no restrictions — from 1×1px to 10000×10000px.
Will my image be stretched?
If the aspect ratio of your target dimensions differs from the original, the image will be stretched. To avoid this, maintain the same width-to-height ratio.
How do I maintain aspect ratio?
If your original is 1000×750px (4:3 ratio), keep the same ratio: 800×600, 400×300, 200×150, etc. Divide both dimensions by the same number.
