If your file is off

  • A photo outside 9:16 to 1.91:1 is cropped to fit. sprkly warns you before you post.
  • In a carousel, every slide is cut to the shape of the first one. sprkly warns you when they differ.
  • A Reel that is not 9:16 plays with bars. sprkly posts video as 9:16 or 3:4, and you can crop in the app.
  • PNG, WebP and GIF are turned into JPEG before Instagram gets them.
