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.
