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

FormatSize (px)Ratio
Square post1080 × 10801:1
Portrait post (recommended)1080 × 13504:5
Landscape post1080 × 5661.91:1

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.

How to resize for Instagram

  1. Open the PressImg compressor.
  2. Drop your image.
  3. Set the width and height to the format you need (e.g. 1080×1350 for a portrait post).
  4. Pick quality, compress, and download.

Everything runs in your browser — your photos are never uploaded to any server.

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.
