Instagram Post Resizer
The 1080×1080 square is Instagram's classic post format and still the safest choice for carousels and a consistent look. Instagram compresses every upload, and images wider than 1080 pixels get scaled down on their servers — so exporting at exactly 1080 wide lets you control the resize yourself instead of leaving it to Instagram's compressor.

How it works
- 1
Add your image
The frame is preset to 1080 × 1080 pixels.
- 2
Position it
Drag to pan and use the zoom slider. Crop-to-fill trims overflow; fit-with-padding keeps everything visible.

What you see is exactly what exports — no surprises after upload.

Common uses
- Product photos for a shop grid that needs a uniform square look
- Carousel slides that must all share the same dimensions
- Artists and photographers posting work without surprise crops
- Social media managers batch-preparing a week of content
- Quote and announcement graphics designed at square proportions
Good to know
- 1080 pixels is the maximum width Instagram serves for feed images — uploading larger just means Instagram downscales it for you, often less carefully.
- Square is not required: a 1080×1350 portrait post takes up more feed space. Use square when carousel consistency matters.
- Export as JPEG at high quality. Instagram recompresses everything, and feeding it a clean JPEG produces fewer artifacts than a huge PNG.
- Keep important elements away from the extreme edges — profile-grid thumbnails can crop differently than the feed view (as of our July 2026 check).

Frequently asked questions
What is the best size for an Instagram post?
For square posts, 1080×1080 pixels — that was Instagram's recommendation when we last verified in July 2026. Portrait posts at 1080×1350 and landscape at 1080×566 are also supported, each with its own preset on this site.
Why does Instagram make my photos look compressed?
Instagram recompresses every image on upload to save bandwidth. You cannot skip that step, but you can minimize damage: upload at exactly 1080 pixels wide, avoid resizing up, and start from a sharp original so there is detail to spare.
Should I post square or portrait on Instagram?
Portrait (1080×1350) occupies more vertical space in the feed, which can help engagement. Square is better when you need every carousel slide identical or want a tidy, uniform grid. There is no single right answer — it depends on the content.
What happens if I upload an image larger than 1080 pixels wide?
Instagram scales it down to 1080 on their servers. The result is usually fine, but doing the resize yourself first gives you control over cropping and sharpness instead of trusting an automated pipeline.
Does resizing here reduce image quality?
Resizing down always discards pixels, but doing it once, deliberately, at high JPEG quality preserves far more detail than letting multiple apps resave the image. Processing happens in your browser, so there is no extra server-side recompression from us.
