Preparing photos for Instagram can be frustrating. If your files have the wrong dimensions or aspect ratios, Instagram’s automatic compression algorithm will aggressively crop your composition or compress the image, leading to pixelation.

  • Square Post: 1080 x 1080 pixels (1:1 aspect ratio)
  • Portrait Post: 1080 x 1350 pixels (4:5 aspect ratio)
  • Instagram Story & Reel: 1080 x 1920 pixels (9:16 aspect ratio)
  • Profile Picture: 320 x 320 pixels (1:1 aspect ratio)

How to Optimize Photos for Instagram

  1. Interactive Cropping: Don’t rely on Instagram’s simple crop tool. Use our built-in Crop Image workspace, select 1:1 or 4:5, and drag the corners to frame your subject exactly.
  2. Resize by Dimensions: Select the Presets tab and choose the corresponding Instagram format. The bounding box values will load automatically.
  3. Format Choices: Use JPG or WEBP for photographs. WEBP provides the smallest file sizes, while JPG offers universal compatibility for social media uploads.
