Why Pre-Resize?

Instagram automatically resizes and compresses uploaded images. By uploading at exactly the right dimensions, you give Instagram less reason to compress, resulting in better-looking posts.

Quality Tips

After resizing, use 90-92% JPG quality. This gives Instagram less room to degrade your image during its own compression process.

Frequently Asked Questions

What size should my Instagram photos be?

For posts: 1080×1080 (square), 1080×1350 (portrait), or 1080×566 (landscape). For Stories/Reels: 1080×1920. These are Instagram's recommended dimensions.

Does Instagram compress images?

Yes, Instagram compresses all uploaded images. Uploading at exact recommended dimensions and high quality (90%+) minimizes the compression impact.

What aspect ratio works best for engagement?

Portrait (4:5) takes up the most screen space in the feed and typically gets higher engagement than square or landscape posts.
