Instagram size cheatsheet
Feed post (square) 1080x1080. Feed post (portrait) 1080x1350. Feed post (landscape) 1080x566. Story 1080x1920. Reels cover 1080x1920. Profile photo 320x320 — the resizer handles all of these with the aspect-ratio toggle.
Lock aspect ratio or stretch?
Use lock when you only want to shrink without distortion (the height auto-fills). Uncheck when you need exact target dimensions, accepting that the photo will be stretched.
Frequently asked questions
Best quality for Instagram?
Source at 1080 wide and JPG quality 80. Instagram re-compresses anything bigger; smaller loses sharpness in the feed view.
Is it actually free?
Yes. No signup, no daily cap on normal personal use, no watermark on the output. Display ads keep the site free.
Does it work on a phone?
Yes. The upload box opens the camera roll on mobile browsers directly.
