What this tool does
Instagram feed posts look sharpest at 1080×1080 (square) or 1080×1350 (portrait) — this tool crops and scales any photo to fill one of those sizes exactly, so nothing gets stretched or squeezed.
How it works
- Upload the photo you want to post.
- Pick square (1080×1080) or portrait (1080×1350).
- The tool centers and crops your photo to fill that frame, then you download it ready to upload.
Example: Upload a 3024×4032 iPhone portrait photo and it comes back a clean 1080×1080 square, centered on the subject — ready to post without Instagram's own crop tool guessing for you.
