How to Resize Images Online

Upload your image and set the new dimensions manually or choose from social media presets. The aspect ratio lock ensures your image does not get distorted — when you change the width, the height adjusts proportionally and vice versa. Unlock the aspect ratio for custom cropping dimensions.

Social Media Image Sizes

Every platform has optimal image dimensions. Instagram posts perform best at 1080×1080 pixels, while Stories need 1080×1920. Facebook cover photos require 820×312, and YouTube thumbnails are 1280×720. Using the wrong dimensions means your images get cropped or stretched, reducing engagement and looking unprofessional.

This resizer includes presets for all major platforms, so you get pixel-perfect dimensions in one click without memorizing specs.
