Resize images to exact dimensions in pixels, centimeters, or millimeters. Set custom size, choose output format, set target file size. Free, private, browser-based.
Upload your image, enter the desired width and height in pixels, cm, or mm, then click Resize. The image is scaled to your exact dimensions.
When locked, changing width auto-calculates height to maintain the original proportions. Click the lock icon to unlock and set width/height independently.
When you choose CM or MM, the tool converts your dimensions to pixels using the selected DPI (dots per inch). 300 DPI is standard for printing.
Yes. Enter a target size in KB or MB. The tool first resizes to your dimensions, then compresses to hit the target size with 99%+ accuracy.
Resizing to larger dimensions increases file size. If you need a specific file size, use the Target Size option — the tool will compress to hit your exact target.
No. Everything runs in your browser. Your images never leave your device.
