About Image Resizer
The Image Resizer changes the width and height of your pictures to exact pixel dimensions. Keep Maintain Aspect Ratio on to scale proportionally, or turn it off to set a custom width and height, with handy presets for common sizes.
Because resizing runs entirely in your browser, your images are never uploaded to a server. It is a quick, private way to prepare pictures for social media, websites, email, and printing.

Frequently Asked Questions
How do I keep the image from looking stretched?
Leave Maintain Aspect Ratio checked. When it is on, changing the width updates the height automatically so the image keeps its original proportions.
Are my images uploaded to a server?
No. Resizing is handled locally in your browser, so your images never leave your device.
Can I resize to exact pixel dimensions?
Yes. Type the exact width and height you need, or pick a preset like 1920x1080 or 500x500 for common sizes.
Will resizing reduce image quality?
Making an image smaller keeps it crisp. Enlarging beyond the original size can look soft, since there is no extra detail to add.
