Image Resizer
Changes the width and height of a picture. The picture is handled inside your browser and is never uploaded.
This tool runs entirely in your browser. Nothing you enter or open is uploaded, transmitted or stored anywhere.
Common questions
Is my picture uploaded to a server?
No. The file is read by your browser and redrawn on a canvas on your own device. Nothing is transmitted, which is why the tool still works with your network disconnected.
Why did my transparent PNG go black?
JPEG cannot store transparency. Choose PNG or WebP to keep a transparent background.
