Wrong aspect ratio
A square logo alone often gets cropped or padded awkwardly. A proper preview canvas gives platforms room to render the mark.
Generate Open Graph Images for Link Previews
Create the image people see when your site is shared in Slack, Discord, LinkedIn, Facebook, X, and other preview surfaces. Start with a logo, choose a size, and export a clean PNG.
Generate an OG imageWhat this generator creates
Open Graph images are the large previews attached to shared links. LogoNuri's generator places your logo on a fixed social canvas and exports PNGs sized for common preview formats, including 1200x630, 1200x600, 1200x627, and square layouts.
Input: a PNG, JPG, or WebP logo. Output: a social preview PNG you can reference in og:image or use as a starting point for platform-specific cards.
This tool creates the image file. It does not update your website metadata, purge link-preview caches, or guarantee every platform will crop the image the same way. After uploading the final image, test the live URL in the platform debugger or by sharing a private test link.
Why link previews break
Cached old metadata
Slack, Discord, X, LinkedIn, and Facebook may keep the first preview they saw until their cache is refreshed.
Tiny or transparent source
A transparent logo with no background can disappear in dark previews. Export a full social image with an intentional backdrop.
Privacy and workflow fit
The standalone OG image generation step runs in your browser. Your logo is drawn to a local canvas and downloaded as a PNG. Network features are only involved when you use accounts, sync, hosted brand assets, or your own deployment pipeline.
Use this when you need a fast, clean preview image for a landing page, app, docs site, or launch post. Use a full design tool when you need campaign-specific copy, photo composition, multi-layer templates, or brand-approved social layouts.

FAQ
A common default is 1200x630. LogoNuri also includes common social variants such as 1200x600, 1200x627, and square output.
No. This page generates the PNG. You still need to upload it and reference it from your page metadata.
Preview platforms cache images and metadata. After changing the file or tags, refresh the platform cache or test with a new URL.
Yes, but a full preview image with a deliberate background usually renders more predictably across apps.
Yes. The standalone canvas export runs in your browser. Accounts, hosted assets, and sync features use network services.
Use one strong 1200x630 default first. Create platform-specific variants when the crop, text safe area, or brand campaign requires it.
