When you share a link to your website or a post on Facebook, Twitter/X, or a chat app, the image that shows up affects whether people click through or scroll past. But each platform wants a different image size — OG Image, Twitter Header, Facebook Cover, YouTube Thumbnail, and Instagram post. This tool bundles all 6 standard size presets in one place — just pick the size you need, type a headline, choose a gradient background or upload your own image, and download it as a PNG instantly. Everything is generated with HTML Canvas in your own browser — no background image is ever uploaded to a server.

Frequently Asked Questions (FAQ)

What is an OG Image, and why do I need one?
An OG Image (Open Graph Image) is the image shown when someone shares your website link on Facebook, Twitter/X, LINE, or other chat apps. Without one set, a shared link can look unappealing or show no image at all. The most common standard size is 1200×630 pixels.
Which preset should I use for which platform?
OG Image works for general link sharing on any platform. Twitter Header and Facebook Cover are for that platform's profile cover image specifically. YouTube Thumbnail is for a video's cover image, and Instagram Post uses a square ratio for a standard feed post.
Is the background image I upload sent to a server?
No data ever leaves your device. All cover image generation runs entirely in your browser via HTML Canvas.
