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".

Frequently Asked Questions

You control the output format and quality. JPG and WebP use the quality slider (90 by default); PNG is lossless.

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.

No. Resizing happens entirely in your browser with the Canvas API. Your photos never leave your device.
