Social Image Resizer
Crop & resize images to exact social media dimensions.
Images are processed in your browser and never uploaded. The crop is centered to the chosen aspect ratio.
Your resized preview will appear here once you choose an image.
The Social Image Resizer crops and scales any image to the exact pixel dimensions each platform expects — Instagram posts and stories, Facebook, X, LinkedIn, and YouTube thumbnails. Pick a preset, and the tool center-crops to the right aspect ratio and exports a PNG or JPEG. Your image is processed in the browser and never uploaded.

Automatically crops to the target aspect ratio from the center so the subject stays in frame.

Frequently asked questions
What size should an Instagram post be?+
A square Instagram post is 1080×1080, portrait is 1080×1350, and a story or Reel is 1080×1920. The resizer includes all three as presets.
Will resizing reduce my image quality?+
Scaling down keeps images sharp; the tool exports at the exact target resolution. For best results, start with an image at least as large as the target size.
Are my images uploaded anywhere?+
No. The image is loaded and resized entirely in your browser using a canvas, so it never leaves your device.
How does the crop choose what to keep?+
It center-crops to the chosen aspect ratio, trimming evenly from the sides or top and bottom so the middle of your image stays in frame.
