Resize a photo for Instagram
Get photos to Instagram’s exact sizes so they don’t get cropped badly or blurred: portrait and square posts, landscape posts and full-screen stories. Free, private, and you can do a batch at once.
Instagram sizes this tool uses
| Use | Size |
|---|---|
| Portrait post (4:5, takes the most room in the feed) | 1080 × 1350 px |
| Square post | 1080 × 1080 px |
| Landscape post | 1080 × 566 px |
| Story or reel cover (9:16) | 1080 × 1920 px |
Pick the size from the list above the drop zone. If your photo is a different shape, it's cropped to fill from the centre, or you can fit it inside and add a border instead. Several photos at once come back in one ZIP.
Why the exact size matters
Instagram resizes and compresses everything you upload. Starting at its own size means it has less to change, so your photo stays sharper, and you choose the crop instead of Instagram choosing it for you.
Your photos stay on your device
Most resizers upload your photo to their server first. This one does the work in your browser, so nothing is sent anywhere. Resizing also leaves out the hidden location and camera details that phones save inside photos.
Frequently asked questions
What is the best size for an Instagram post?
For most posts, 1080 × 1350 pixels (4:5 portrait). It fills the most space in the feed. Square 1080 × 1080 also works well.
What size is an Instagram story?
1080 × 1920 pixels, a 9:16 shape that fills a phone screen. Keep text away from the very top and bottom, where Instagram puts its buttons.
My photo is a different shape. What happens?
By default it’s cropped to fill from the centre. Choose “Fit inside and add a border” to keep the whole photo with a coloured border instead.
Can I resize several photos at once?
Yes. Select them all and you get one ZIP with every photo at the same size.
Is anything uploaded?
No. Resizing runs in your browser and your photos never leave your device.
