Frequently asked questions
What is the Instagram feed post (square) size?
A standard square Instagram feed post is 1080×1080 px (1:1 aspect ratio). Portrait posts are 1080×1350 and landscape 1080×566. Resize to 1080×1080 with TryQuickImg in your browser — nothing is uploaded.
How do I resize my image for Instagram without losing quality?
Resize to the exact pixels (1080×1080) rather than cropping randomly, and start from the highest-resolution original you have. TryQuickImg draws the resized copy on a canvas in your browser, so there is no re-upload and no quality-stealing server round-trip.
Is my photo uploaded to TryQuickImg?
No. TryQuickImg runs in your browser. After the page loads you can go offline and still resize — nothing is posted to a server.
