OG Image Maker — 1200×630

Open Graph images control how your links appear when shared on Facebook, Slack, Discord, iMessage, and dozens of other platforms. The standard size is 1200×630 pixels with a 40:21 aspect ratio. Getting the dimensions right means your content stands out in feeds instead of being awkwardly cropped or stretched by the platform.

Why use this tool?

Upload any image and the crop area locks to the 40:21 OG ratio. Drag or resize the selection to frame exactly the part you want, then export as PNG, JPG, or WebP with full control over quality. The live dimension readout confirms you are exporting at precisely 1200×630. Your files are processed entirely inside your browser using built-in Web APIs and are never uploaded to any server, so there is nothing to install and nothing leaves your device.

Frequently asked questions

Is the OG Image Maker free?

Yes. It is completely free with no watermark, no sign-up, and no limit on how many images you can crop and export.

Is my file private and secure?

Completely. Your file is processed 100% inside your browser using the Web APIs built into your device. Nothing is uploaded to any server — imgic never sees, stores, or transmits your images. You can even use these tools offline once the page has loaded.

What is an Open Graph image?

An Open Graph (OG) image is the preview thumbnail shown when a URL is shared on social platforms, messaging apps, and search results. Setting one at 1200×630 ensures a clean, uncropped preview everywhere.

Which export format should I choose?

PNG is best for graphics and text-heavy images because it is lossless. JPG works well for photographs and keeps file size small. WebP offers the best balance of quality and size for the modern web.

Can I use this tool offline?

Yes. Once the page has loaded, the entire tool runs inside your browser with no network requests. You can disconnect and continue cropping and exporting without interruption.
