Instagram Post Size
1080 x 1080 px (1:1).
A Instagram post (square) is 1080 x 1080 pixels (1:1). Resize and crop any image to this exact size right in your browser. Nothing is uploaded, so your image never leaves your device. Drop a file below, pick this preset, and download it ready to post.

Tips for Instagram
- Instagram displays feed images at 1080 px wide, then compresses. Upload at exactly 1080x1080 so it never upscales a smaller file.
- For a portrait post use 1080x1350 (4:5), which takes more vertical space in the feed.
- Avoid uploading larger than 1080 px wide: Instagram downsizes it and the extra compression softens the image.
