Instagram Post Resizer – Questions & Answers

How do I post a full landscape photo on Instagram without cropping?
Use our "Contain" fit mode with 1080x1080. It places your entire landscape photo in the center and adds clean white (or chosen color) borders above and below.
What is the highest quality resolution for Instagram posts?
1080 pixels width is Instagram’s native display width. Anything higher gets compressed by Instagram; anything lower looks blurry.
Can I resize multiple photos for an Instagram carousel?
Yes, upload multiple photos and download them all in a ZIP file.
Does this app require an account or app download?
No app download or account needed. Works instantly in your mobile browser.
