How to Resize an Image Without Distorting It

How to resize an image without distorting it
An image looks stretched when its width and height are changed independently. To keep people, objects and logos looking natural, preserve the original aspect ratio.
Understand aspect ratio
Aspect ratio describes the relationship between width and height. A 1600 × 1200 image has a 4:3 ratio. If you reduce its width to 800 pixels while keeping the ratio, its height becomes 600 pixels.
Use proportional resizing
Open Pixvello Resize Image. Enter the new width or height and keep the lock-ratio option enabled. The other dimension should update proportionally.
When to crop instead
Sometimes a platform requires a fixed shape, such as a square avatar or a 16:9 thumbnail. If the original ratio is different, cropping is usually better than stretching. Use Pixvello Crop Image to choose the visible area.
Choose suitable output dimensions
Do not enlarge a small image unnecessarily. Upscaling with ordinary resizing adds pixels but does not recover missing detail. For web use, export close to the maximum display size needed.
Check the result
Compare circles, faces and straight lines with the original. If they look wider, narrower or warped, check that the aspect-ratio lock was enabled.
Summary
Preserve the aspect ratio for normal resizing. Crop when a fixed frame is required, and avoid enlarging small images unless you accept that the result may look softer.
Frequently asked questions
What does keeping the aspect ratio mean?
It means width and height change proportionally, preserving the original shape instead of stretching or squashing the image.
Should I crop or resize to make a square image?
If the image must be square, crop it to the desired composition. Resizing a non-square image directly to a square will distort it.
Does increasing pixel dimensions improve image quality?
Ordinary resizing creates additional pixels but cannot restore detail that was not present in the original image.
