About the Instagram Post Resizer
Instagram displays square feed posts at 1080×1080 pixels, and uploading anything else means it gets cropped or compressed unpredictably. This resizer crops your photo to fill a perfect 1080×1080 square from the centre, so your post looks exactly as you intended.

Frequently Asked Questions
What is the best size for an Instagram post?
1080×1080 px for square posts. Instagram also supports 1080×1350 (4:5 portrait) and 1080×566 (landscape).
How do I resize a photo for Instagram?
Upload it here and download the 1080×1080 result, ready to post.
Will my photo be cropped to a square?
Yes — to fill the square without stretching, the centre of the photo is kept and the edges are trimmed.
How do I post a full photo on Instagram without cropping?
Use the 4:5 portrait format or add borders in an editor; this tool fills the square by cropping.
Why does Instagram make my photos blurry?
Instagram recompresses images that aren’t the expected size. Uploading at exactly 1080 px wide reduces extra compression.
What size is an Instagram profile picture?
It displays at 110×110 but upload at least 320×320. Square Crop plus Resize Image by Pixels works well.
What size is an Instagram carousel?
Use the same size for every slide — 1080×1080 square or 1080×1350 portrait.
Can I resize for Instagram Stories here too?
This tool makes square posts. Stories are 1080×1920 — use the Instagram Story Resizer for those.
Does the format stay the same?
Yes, the resized image keeps its original format (JPG stays JPG).
Does the Instagram Post Resizer store my photos?
No, they’re resized in memory and deleted immediately.
