Frequently Asked Questions
Does resizing affect image quality?
Shrinking the dimensions usually causes no noticeable quality loss, but enlarging an image beyond its original size can make it look blurry, since the tool has to generate pixel data that never existed.
Can the aspect ratio be kept automatically?
Yes, when you enter only the width or only the height with the ratio lock enabled, the other value is calculated automatically to avoid distorting the image.
What size is best for website images?
It's generally best to keep full-width background images under 1920px wide, or 800-1200px for images inside article content, to reduce load time.
Can I resize several images with the same dimensions at once?
Yes, you can upload a batch of images and apply the same width or height to all of them in one operation.
Are my images uploaded to a server?
No, resizing happens entirely inside your browser using Canvas.
What's the difference between resizing and cropping?
Resizing recalculates the dimensions of the entire image, while cropping only cuts out part of the original image.
Does enlarging an image improve its quality?
No, enlarging an image beyond its original size doesn't add new detail, and can make it look less sharp.
