FAQs

What size should an OG image be?

Use 1200×630 for most platforms. Switch presets for Twitter (1200×600) or square (1080×1080).

Does OG Canvas require a login?

No. Everything runs in your browser and exports PNG locally.

Can I save images to the server?

Yes — implement /marketing/og-upload.php to accept a base64 PNG and return a public URL.

Will images look sharp?

The PNG export uses a 2× multiplier by default for crisp results on high-DPI screens.
