Resize Image for Instagram
Instagram shows posts at 1080 px wide and re-compresses anything it doesn't like. Resize to the exact size first (square, 4:5 portrait, 3:4 grid or 9:16 story) and crop to fill so nothing gets stretched or cut off unexpectedly. Runs entirely in your browser.
How to use the Resize Image for Instagram
- Add your photo: Drop, paste or browse for any JPG, PNG, WebP or GIF image.
- Pick the size: Square post (1080×1080 px) is pre-selected; Portrait post 1080×1350, Grid portrait 1080×1440, Story / Reel 1080×1920, Landscape post 1080×566, Profile photo 320×320 are one click away. Crop to fill keeps it undistorted.
- Download: Check the live preview and download. Everything runs on your device.

Frequently Asked Questions
What is the best image size for an Instagram post?
1080×1350 px (4:5 portrait) takes up the most room in the feed. 1080×1080 (1:1) is the classic square. Instagram displays feed images 1080 px wide, so larger uploads are simply downscaled and re-compressed.
What size is an Instagram story or Reel cover?
1080×1920 px, a 9:16 vertical frame. Keep text and faces away from the top and bottom ~250 px, where the profile bar and reply box overlay the image.
Why does Instagram crop or blur my photo?
Images outside Instagram's supported aspect ratios get cropped, and very large files are re-compressed. Resizing to an exact Instagram size with Crop to fill gives you control over the crop and keeps the image sharp.
Is the Instagram resizer free and private?
Yes. It's free, with no sign-up or watermark, and your photos are resized on your device. Nothing is uploaded.
