Resize Images to Exact Instagram Dimensions

Pick a preset and every uploaded image is resized to the exact pixel dimensions Instagram expects — no guessing, no manual cropping.

Choose Fill to center-crop the image to the frame, or Fit to keep the whole photo with a background color padding. All processing runs locally in your browser.

Exact Platform Dimensions

1080x1080 square, 1080x1350 portrait (4:5), 1080x566 landscape, and 320x320 profile pictures — matching the official recommended sizes.

Fill or Fit

Fill center-crops to cover the frame; Fit keeps the entire photo and pads the edges with your chosen background color.

Batch Processing

Resize a whole set of photos to the same preset at once and download everything as a single ZIP archive.

How to Use

Upload one or more images.

Pick a preset and fit mode.

Click "Resize Images".

Download individually or as ZIP.

Frequently Asked Questions

Yes. Upload as many images as you like, and every one is resized to the selected preset. Download them individually or all together as a ZIP.
