Social Media Image Resizer

Every platform crops what you give it to the shape it wants, and it never crops where you would have. A wide photo posted to Instagram loses its sides; a square one posted to X sits small in the middle of the card; a LinkedIn cover designed as a normal image has its subject sliced off. Uploading something already the right shape is the only way to control what survives.

Twenty-six sizes are here, covering Instagram, Facebook, X, LinkedIn, YouTube, TikTok, Pinterest, WhatsApp and the Open Graph image that shows when a link is shared anywhere at all. Each one says what it is for and what to watch out for — that a YouTube banner is mostly invisible except for its centre, that text in the bottom third of a TikTok cover is hidden behind the caption.

Two ways of dealing with a mismatch, and neither of them stretches the picture. Cropping to fill takes the centre and loses the edges, which is right for a photograph. Fitting keeps the whole image and adds white bands, which is right for a graphic or a logo where losing an edge would be worse than the bands.

What no resizer should do, and several do, is squash the image to the target dimensions. It is the one transformation that makes a picture look obviously wrong, and it is never offered here.

The sizes are correct as of the date shown under the preview. Platforms change them without notice, and being slightly off is rarely a problem — what matters is the aspect ratio, because that is what gets cropped. Everything runs on your device and no image is uploaded.
