The size

1200×630 at 1.91:1 for link previews

When a page is shared, platforms read its Open Graph image and show it as a card. The widely supported size is 1200×630, a ratio of about 1.91:1, which Facebook, X (Twitter), LinkedIn, Slack and Discord all display cleanly. This cropper locks the box to that ratio; type 1200 as the width and the height becomes 630 automatically. A correctly sized image avoids the awkward cropping or tiny thumbnail that happens with the wrong shape.

Readable at small sizes

Design the card for a feed

Share cards are shown small, so keep the title text large, center the key element, and leave margin around the edges where some platforms overlay a domain label. Export PNG for crisp text and logos or JPG for photos. Set the image as your page’s og:image at this size and most networks will use it directly.

Where it shows

Per-platform link cards

An Open Graph image is the picture that appears when your link is shared. At 1200×630 it renders as a large card on Facebook and LinkedIn, as a big summary card on X (with twitter:card set to summary_large_image), and as a preview in Slack, Discord and many chat apps. Using the wrong shape leads to a cropped or tiny thumbnail, which is why this tool locks the 1.91:1 ratio. One well-cropped 1200×630 image generally satisfies every major platform, so you rarely need a separate picture per network.

Setup

Set it as og:image and twitter:image

To use the result, add it to your page head as <meta property="og:image" content="..."> (and twitter:image for X), using an absolute URL. Keep the file reasonably small — most platforms prefer well under a few megabytes — so export JPG for photographic cards or PNG for crisp text and logos. After publishing, use a platform’s sharing debugger to refresh the cached preview. If you also need on-platform banners rather than link cards, the Facebook cover and Twitter header croppers preset those, and crop by size handles any exact dimensions.

Free & private

Free, no watermark, nothing uploaded

The OG Image Cropper costs nothing, adds no watermark and asks for no login. Because it works entirely on the HTML canvas in your browser, your images never leave your device, so it is both quick and genuinely private, and it continues to function offline after the first load. It works identically across Windows, macOS, Android and iOS, supports both mouse and touch dragging, and lets you process one image after another without a page refresh. Download as PNG or WebP to retain transparency, or choose JPG for the most compact photo file. The crop frame is locked to the right shape, so every result is consistent without manual measuring.
