About this tool
Instagram compresses photos that are far larger than it needs and can crop images that don't match its expected aspect ratios. Scaling your photo to 1080px on the longest edge ahead of time — the resolution Instagram actually displays at — means less recompression and a cleaner result in the feed.
Unlike Instagram's own in-app cropping, this tool never cuts any part of your photo off; it only scales the whole image down to fit the size Instagram expects.
Questions
Will this force my photo into a square?
No — it keeps your original aspect ratio; Instagram supports portrait, square and landscape posts.
Why 1080px?
That's the resolution Instagram displays full-size photos at, so there's no benefit to uploading larger — it just gets recompressed harder.
Does this work for Stories or Reels too?
It's best suited for feed posts; Stories and Reels use a taller 9:16 canvas.
