Instagram Image Resizer

Resize images for Instagram while keeping quality.

Resize an image to Instagram's expected dimensions — Square 1080×1080, Portrait 1080×1350, Story / Reel 1080×1920 — without the soft, stretched result you get from dragging a corner in a slide deck. It crops to fill the frame from the centre and keeps the original resolution, so the upload stays sharp.

How to use the Instagram Image Resizer

  1. Upload your image.
  2. Pick the Instagram format you need.
  3. Check the crop — anything important should sit near the centre.
  4. Download the resized file and upload it.

Frequently asked questions

What image size does Instagram use?

Square 1080×1080, Portrait 1080×1350, Story / Reel 1080×1920. Uploading at those dimensions avoids Instagram re-compressing the file to fit, which is where most of the visible quality loss comes from.

Does resizing lose quality?

Scaling down is close to lossless at these sizes. Scaling a small image up is not — start from the largest original you have.

Is my photo uploaded to a server?

No. The resize runs on a canvas in your own browser; the file never leaves your device.

Why is my image cropped, not squeezed?

Because squeezing distorts faces and logos. The tool fills the frame from the centre and trims the overflow, which is what the networks themselves do.
