What is the Image Resizer?
Resize any JPG, PNG or WebP image using exact pixel dimensions, a percentage scale, or ready-made presets, with an aspect-ratio lock so proportions stay correct unless you want to stretch on purpose. A draggable resize handle on the live preview lets you resize visually and see the exact width/height in a tooltip as you drag.
Before downloading you can fine-tune the output quality with a compression slider, and the info panel next to the preview shows the current image dimensions and file size so you can judge the tradeoff between size and quality.
