FAQ
Can I keep the aspect ratio?
Yes. The aspect ratio lock keeps width and height proportional when you change one of them.
Can I resize by percentage?
Yes. Set scale by percent (e.g. 50%) or absolute pixels — whichever fits your workflow.
Can I resize many images at once?
Yes, batch resizing is supported with a ZIP download of all results.
