Image Resizer
Resize images to the exact dimensions each social platform expects — free, private, in your browser.
Introduction
Upload a photo sized for one platform and it can get awkwardly cropped or squeezed on another. This tool resizes any image to a specific platform's recommended dimensions — or any custom size you need — entirely on your device, with nothing uploaded to a server.
How the Tool Works
Choose an image, then pick a platform preset or enter a custom width and height. With “Lock aspect ratio” on, changing one dimension scales the other proportionally so nothing stretches. Download the result as a PNG once the preview looks right.

Tips
- Keep “Lock aspect ratio” on unless you specifically want to crop or stretch the image.
- Start from your highest-resolution original — resizing down preserves quality better than resizing a small image up.
- Use the exact preset for where the image is going — a few pixels off can still trigger an unwanted crop on some platforms.
