How to Resize an Image for Instagram
Updated 2026 · 5 min read
Uploading a photo at the wrong size to Instagram leads to unwanted cropping, stretched faces, or a blurry feed. The fix is simple: resize and crop your image to Instagram's recommended dimensions before you upload.
Recommended Instagram image sizes
- Square post: 1080×1080 px
- Portrait post: 1080×1350 px (4:5)
- Landscape post: 1080×566 px (1.91:1)
- Story / Reel: 1080×1920 px (9:16)
- Profile picture: 320×320 px (displayed as a circle)
How to resize for Instagram
- Open the Aaroka Image Resizer.
- Upload your photo.
- Enter the width and height for the format you need (for example 1080 and 1350).
- Uncheck "Maintain aspect ratio" if you want to force an exact size, or leave it on to avoid distortion.
- Process and download, then upload to Instagram.
Tips for crisp Instagram images
- Export as JPG at quality 0.85 – 0.9 for a good size/quality balance.
- Keep the shortest side at 1080 px so Instagram does not upscale and blur it.
- Crop first, then resize, so you control what gets cut — not Instagram.
Frequently asked questions
Why are my Instagram photos blurry?
Usually because the original was smaller than the display size and Instagram upscaled it. Start with at least 1080 px.
Should I use PNG or JPG?
Use JPG for photos; PNG only for graphics with sharp edges or transparency.
Does resizing upload my photo anywhere?
No. The resize happens entirely in your browser.
