Resize & Compress Images for Instagram
Instagram compresses every image you upload — and if your photo isn't sized right, it gets cropped or turns blurry. Resize to the exact dimensions and compress before uploading, so your posts stay sharp. Free, in your browser, nothing uploaded.

Instagram image sizes in 2026
| Format | Size (px) | Ratio |
|---|---|---|
| Square post | 1080 × 1080 | 1:1 |
| Portrait post (recommended) | 1080 × 1350 | 4:5 |
| Landscape post | 1080 × 566 | 1.91:1 |
| Story / Reel | 1080 × 1920 | 9:16 |
| Profile grid preview | 1080 × 1440 | 3:4 |
| Profile photo | 320 × 320 | 1:1 |
In 2026 Instagram favors portrait 4:5 (1080×1350) — it takes the most space in the feed. The profile grid now crops previews to 3:4, so keep faces, text and logos centered. Always upload at 1080px width: smaller looks soft, larger just gets compressed by Instagram anyway. Keep files under 10 MB to avoid heavy quality loss.
Why compress before uploading?
Instagram re-compresses everything you post to save space — and you don't control how. If you upload a clean, properly compressed 1080px image, you decide the quality instead of letting Instagram degrade it. Compressing first also means faster uploads, especially on mobile data.
