How to Resize Photos for Instagram without Cropping?

Instagram automatically crops photos that don't match its specific aspect ratios. This often cuts off heads in vertical photos or friends in group photos. Our tool helps you fit the full image by adding a clean white background.

Instagram Size Guide (2025):

Square Post (1:1): 1080 x 1080 px. The classic format suitable for most posts.
Portrait Post (4:5): 1080 x 1350 px. This is the best format for visibility as it takes up more vertical screen space on mobile feeds.
Story / Reel (9:16): 1080 x 1920 px. Full screen vertical format. Use this for Stories, Reels, and IGTV covers.
Profile Picture: 320 x 320 px. We recommend using 1080x1080 to ensure it looks sharp even when clicked.

The "No Crop" Trick:

If you have a wide landscape photo but want to post it as a Square or Portrait, select the desired size button above, then use the Zoom Slider to shrink your image slightly. This will create a "Letterbox" effect (white bars), preserving your full image.
