Quick answer
To make a square Instagram feed post, resize your image to 1080×1080 pixels. Open Resize Image with the 1080×1080 preset, drop your JPG, PNG, or WebP, and download — everything happens on your device, not uploaded to our servers for processing.
- Convert HEIC if needed — iPhone photos are often HEIC. Use HEIC to JPG first.
- Resize to 1080×1080 — open the tool with this size pre-filled and download the result.
- Compress if there's a size cap — some uploads also limit KB. Use Compress Image after resizing.
What to watch for at 1080×1080
- Aspect ratio
- 1:1
- Pixels
- 1.17 MP
- At 300 DPI
- 3.6″ × 3.6″
- Instagram re-encodes every upload, so sending a 4000 px original does not buy you a sharper post — it just gives Instagram more to throw away. Export at 1080 px and the recompression has less work to do.
- The square is no longer the default feed shape. A 4:5 portrait at 1080×1350 occupies noticeably more screen as someone scrolls; use the square when the composition is genuinely centred.
- The grid thumbnail is a centre crop of your square, so nothing important should sit near the edges.
