How to use the social media image resizer

  1. Add your image. Drop in a photo, graphic or screenshot, ideally at least 2,000px wide so every size stays sharp. A sample image is loaded first.
  2. Pick a size and frame it. Choose a size from the list, then drag the preview to move the crop and scroll (or use the Zoom slider) to zoom. Each size remembers its own framing.
  3. Check the guides. Dashed boxes show the area that’s visible on every device, such as the middle strip of a YouTube banner. Profile photos are shown inside the circle they’ll be cropped to.
  4. Download. Download the size you’re looking at, or tick several sizes and download them all as a ZIP, named by platform and size.

Why each platform needs its own crop

A wide X header, a square Instagram post and a tall story all crop the same picture very differently. Uploading one image everywhere means the platform crops it for you, which often cuts off faces, logos or text. Framing each size yourself keeps the important part in view.

Safe areas

Some images are cropped differently on phones, tablets, desktops and TVs. YouTube banners are the extreme case: the full 2560×1440 image only shows on TVs, while phones show just the central 1546×423 strip. Stories and TikTok covers hide the top and bottom behind buttons and captions. Keep text and logos inside the dashed safe areas.

Sharper results on high-resolution screens

LinkedIn company covers and Facebook covers are displayed at small sizes but viewed on high-density screens, so Refract exports them at twice the size for crisper results. Platforms recompress every upload, so save at high quality: 85 or more for JPEG.

Frequently asked questions

Is my image uploaded?

No. Every crop is created in your browser and saved straight to your device.

Are these sizes up to date?

They match the sizes each platform recommends as of October 2026. Platforms change their layouts from time to time, so check their help pages if something looks off.

What size should a link preview image be?

1200×630 pixels is the standard Open Graph size used by Facebook, LinkedIn, X, Slack and most messaging apps. Keep important content away from the edges, as some apps crop it to a square.

Why does my image look blurry after uploading?

Usually because the source is smaller than the size it’s shown at, or because the platform compressed it heavily. Start with a large image and save at high quality.
