Instagram crops, scales, and recompresses every image you upload. If your dimensions are wrong, Instagram's automatic cropping cuts off faces, text, or key details. Getting the right pixel dimensions before upload avoids all of this. Glopix provides all 12 Instagram image presets — posts, stories, reels, profile photos, and more — with a visual preview of the crop before you download.

Frequently Asked Questions

What size should Instagram posts be? expand_more

Square post: 1080×1080px. Portrait post: 1080×1350px (best for feed reach). Landscape: 1080×566px. Story/Reel: 1080×1920px. All available as presets at /imagetools/instagram/.

Why does Instagram crop my photos automatically? expand_more

Instagram fills all posts to its own display containers. If your image ratio doesn't match the displayed format, Instagram automatically crops the edges. Upload at the correct ratio to control the crop yourself.

What's the best format to upload to Instagram? expand_more

JPG is Instagram's preferred format. PNG is accepted but converted to JPG on upload. Upload at the correct pixel dimensions at the highest quality you have — Instagram will compress it anyway.

Does Instagram compress uploaded photos? expand_more

Yes — Instagram recompresses all images to approximately 85–90% JPG quality. Start with the highest quality source file at the correct dimensions to minimise double-compression artefacts.
