Free, runs entirely in your browser — no sign-up, no file upload to a server.
What does the Image Resizer do?
It resizes an image to exact pixel dimensions or a percentage scale, with an option to lock the aspect ratio so it never distorts.
How do I use it?
Drop an image, enter a target width/height (or percentage), and download the resized file.
Which formats are supported?
Any image format your browser can decode can be loaded; the resized image downloads in the same format family the tool renders (PNG/JPEG/WebP depending on the source).
Is there a size limit?
There's no artificial cap — very large images just take a little longer since everything is resized locally in your browser.
Where is my image processed?
Locally, via the Canvas API. Nothing is uploaded anywhere.
What should I do if the tool fails?
Make sure the file is a genuine image and not corrupted, and try a smaller target size if your browser runs out of memory on a very large source image.
