Frequently Asked Questions

What is this tool for?

It creates Open Graph and Twitter or X preview images — the cards that appear when your link is shared — along with LinkedIn banners and YouTube thumbnails.

What size should an Open Graph image be?

1200 by 630 pixels is the standard for Open Graph and large Twitter cards, and this tool exports at that size by default.

Is anything uploaded?

No. Your text and design choices stay in your browser. You download the finished PNG when you are ready.

Do I need design skills?

No. Start from a preset, change the text and colors, and export. The layout and safe margins are handled for you.
