Social Media Image Resizer & Cropper
Drop an image, pick a platform size, and download it perfectly cropped — no design tool, no account, no upload. Everything happens right in your browser.
The right size for every placement
Uploading a landscape photo to a vertical Story, or a wide banner where a square belongs, means awkward auto-crops that chop off heads and text. Pick the exact target size here and decide how the image fits — crop to fill for a centered subject, or fit & pad to keep the whole frame — then download a pixel-perfect copy.
