Free social media image resizer

One image in, every platform size out. Drag each frame to choose the crop, then download the PNGs.

Every platform wants a different shape: 4:5 and square posts, 9:16 stories, 16:9 thumbnails and wide banners. Rotion’s resizer makes all of them from one picture at once, with the crop centred so you only adjust the ones that need it. It all happens in your browser, so your picture never leaves your device.

How to resize an image

  1. Upload your image Drop in a PNG, JPG, WebP or GIF, or paste it. Start from the largest original you have.
  2. Pick the sizes and the fit Tick the formats you need, or add a custom size. Crop to fill suits photos; fit whole image keeps a logo or design complete, on a colour, blurred or transparent background.
  3. Adjust and download Drag the picture inside any frame and zoom to choose what stays in, then download one PNG or all of them.
