About social media image resizer

Social media image resizer takes one picture and produces it at every size the major platforms ask for, in a single pass. Platforms keep changing their recommended dimensions, and cropping an image separately for each one is a repetitive, error-prone chore.

Every size here crops rather than scales. A 4:3 photo posted to Instagram becomes a square with the sides cut off, and a 16:9 banner needs an extreme aspect ratio that crops almost everything away. The tool offers each size as a separate download so you can choose the crop that suits the content, rather than accepting one automatic compromise for every platform.

One important caveat: the dimensions below are the widely used recommended sizes, and platforms adjust them periodically. Before a print or a formal submission, check the platform's own current guidance. The tool produces images at the correct pixel count for each platform, but it does not resize text overlays, so a caption baked into the picture may not survive an extreme crop.

Frequently asked questions

Are these the current platform sizes?

They are the widely used recommended dimensions. Platforms change them from time to time, so check their own documentation before a formal submission or a large campaign.

Will my image get cropped?

Yes. Each size is produced by cropping to the exact aspect ratio, because that is the only way to fill the frame properly. Choose a source image with room around the subject so the crop does not cut anything important.

Why do I get several files from one image?

Because a single square cannot serve a story and a banner at once. Each selected size is a separate, correctly dimensioned export, named for its platform.

Can I upload a whole set of images at once?

Yes. Add as many source images as you like and every selected size is produced for each one.

Does it add text or a watermark?

No. You get clean crops at the right dimensions. If you need text on the image, add it afterwards in a design tool or an editor.

Are the files uploaded?

No, all cropping and resizing happens in your browser.
