Frequently asked questions
What size is an Instagram post?
1080×1080 px for a square post, 1080×1350 px for a portrait post and 1080×1920 px for a Story or Reel.
Does resizing reduce quality?
Making an image smaller is fine. Enlarging it beyond its original size can make it blurry.
Can I resize by percentage?
Yes, pick a percentage (50%, 25%…) or exact width and height in pixels.
Does quality drop?
Downsizing keeps the image sharp; only enlarging loses sharpness.
