How to resize a photo for social media

Crop or fit?

When your photo's shape doesn't match the size you need, something has to give. Crop to fill keeps the frame full and trims the edges; slide the position to choose what stays. Fit keeps the whole photo and fills the gaps, either with a blurred copy of the photo, which looks natural for stories, or with a colour you choose.

The sizes are what each platform recommends as of October 2026. Uploading at these sizes means the app doesn't have to crop or rescale your picture, so it looks the way you made it.

Resizing happens in your browser with your device's own graphics. Nothing is uploaded.

Frequently asked questions

What size is an Instagram post?

1080×1350 for portrait (the most space in the feed), 1080×1080 for square, and 1080×1440 to match the 3:4 profile grid. Stories and Reels are 1080×1920.

What size is a YouTube thumbnail?

1280×720 (16:9), under 2 MB. Channel banners are 2560×1440, with the important part in the middle 1546×423.

Will resizing reduce quality?

Shrinking a photo keeps it sharp. Making a small photo bigger than its original size will look soft, so start from the largest version you have.

JPG or PNG?

JPG for photos: much smaller files. PNG for graphics with text or flat colours, where it stays crisper.
