Free Instagram Post & Story Resizer – Perfect Sizes for Every Instagram Format
Wrong sizes lead to cropped faces, blurry photos and ugly black bars. This free Instagram resizer turns any picture into the right size for a feed post, Story, Reel cover or profile picture in seconds. Crop to fill the frame, or keep the whole photo with a blurred or colored background. A built-in preview shows how your image looks in the feed and on the 3:4 profile grid, and a safe-area guide shows where Instagram buttons cover a Story. Everything runs in your browser, so your photos stay private.

Instagram does not publish one fixed list, and it changes formats from time to time, so treat these as safe, widely used sizes. Instagram's profile grid now shows posts as 3:4 tiles, so keep faces, logos and text in the middle of 4:5, square and landscape posts. For Stories, keep important text away from the top and bottom, where Instagram buttons appear.
Tips for Better Instagram Images
- Start with the sharpest, largest original you have. Enlarging a small photo makes it blurry.
- Use 4:5 portrait for most feed posts, because it takes up the most screen space.
- Keep the subject in the middle so it looks good in the feed and on the profile grid.
- For landscape photos in a Story, use Fit whole image with the blurred background.
- For a carousel, the first image sets the shape for the others, so resize all slides to the same size.
Frequently Asked Questions
What is the best Instagram post size?
1080 × 1350 pixels (4:5 portrait) is the most recommended size for feed posts. Square 1080 × 1080 and tall 1080 × 1440 (3:4) also work well.
What size is an Instagram Story?
1080 × 1920 pixels with a 9:16 ratio. Keep important text away from the top and bottom edges, where Instagram buttons appear.
Is this Instagram resizer free?
Yes. It is completely free, with no signup, no watermark and no daily limit.
Is my image uploaded to a server?
No. Resizing happens entirely in your browser. Your image is never sent anywhere or stored. Blogger or other analytics services on this site may collect general visit data separately, as described in our Privacy Policy.
How do I post a landscape photo to an Instagram Story without cropping?
Choose the Story size, then choose Fit whole image with the Blurred copy background. Your full photo stays in the middle and the empty space is filled with a soft blur.
Why is my post cropped on my profile?
Instagram's profile grid shows 3:4 tiles. Posts in other shapes are trimmed to fit. Use the safe-area guide to keep key parts inside the middle.
What is the profile picture size?
Instagram shows it as a small circle. Upload a square image, 320 × 320 pixels or larger, with your face or logo in the center.
Can I use it on my phone?
Yes. Choose a photo from your gallery, use the Zoom slider and drag the crop box by touch, then save the result and post it from the Instagram app.
