Good to know
Questions, answered
What size should an OG image be?
1200 × 630 px. It's the size Facebook, LinkedIn, X and most chat apps use for large previews, and it's what this tool makes.
Why isn't my new image showing when I share?
Platforms cache previews. Use LinkedIn's Post Inspector or Facebook's Sharing Debugger to refresh the cached version after you update the meta tags.
PNG or JPG?
PNG keeps text perfectly sharp. Choose JPG if you added a photo and want a smaller file.
Is anything uploaded?
No. Everything runs in your browser, so your files never leave your device.
