Social Media Image Resizer

Resize and crop a photo to common social media sizes such as a square post, 9:16 story, 16:9 thumbnail, link preview, or profile header.

About Social Media Image Resizer

Each social platform displays images at its own aspect ratio, and an image with the wrong shape gets cropped automatically, often badly. This resizer scales your photo to one of nine common pixel sizes. Fill mode covers the whole frame and trims what overflows, from the centre or from an edge you choose. Whole image mode keeps everything visible and pads the rest with a solid color. Platforms change their recommended sizes from time to time, so check current guidance for critical work.

How to use Social Media Image Resizer

Set "Target size", "Fit", "Bar color" and "Crop position". The preview updates as you change them.
Check the preview, then press "Download result" to save the file.
