Frequently asked questions
These short answers help search visitors confirm the tool fit without leaving the page.
What is Resize Image by Width best for?
Use it when a platform lists a required width and you want the height to follow naturally from the original image ratio.
Does Resize Image by Width keep the aspect ratio?
Yes. This page is designed for width-led resizing where the other side adjusts automatically unless the workflow explicitly changes the crop.
What should I do after setting the width?
If the upload still fails because of file size, run the resized image through compression next.
