Image Resizer is a 100% free, browser-based utility that enables you to resize images to exact pixels or by percentage. Unlike traditional cloud converters, all processing executes locally on your device with zero server uploads, delivering immediate results and ironclad data privacy.
About the Image Resizer
Need a 1080×1080 image for Instagram, a 1200-pixel-wide banner or a smaller photo for a form that limits dimensions? The Image Resizer scales your picture to exact pixel sizes or by a percentage, with high-quality smoothing so it stays sharp.
Keep the aspect ratio locked to avoid stretching, or unlock it to set width and height independently. You can also change the format and quality while you resize.

Frequently asked questions
Will resizing reduce image quality?
Making an image smaller keeps it sharp with high-quality bicubic smoothing. Enlarging an image beyond its native resolution cannot add detail that was not there, so large upscales will look softer.
What does "lock aspect ratio" do?
It keeps the width-to-height proportion of the original. When you change the width, the height is calculated automatically so the image is not stretched or distorted.
What is the maximum size I can resize to?
Up to 10,000 pixels on each side, which is above the limit most browsers can safely handle for a single canvas.
