Frequently Asked Questions
Got questions? Find clear answers below.
What is the Twitter Card image size?
The recommended Twitter Card image size is 1200 pixels wide by 628 pixels tall, which corresponds to an exact 1.91:1 aspect ratio. This size is the official standard for Twitter (X) Large Summary Cards (summary_large_image). Uploading an image with these dimensions guarantees your post displays a full-width, high-resolution preview across both desktop and mobile feeds without clipping.
Is 1200x628 still recommended?
Yes, 1200x628 pixels is still the primary recommended standard for Twitter summary_large_image cards and Open Graph web previews. While a 1200x675 px (16:9) ratio is common for regular post media uploads, 1200x628 (1.91:1) is the universal web standard accepted by X, LinkedIn, Facebook, and messaging platforms for link preview cards.
What is an Open Graph image?
An Open Graph (OG) image is the featured image defined in your webpage HTML head via the <meta property="og:image" content="..."> tag. When your webpage URL is shared on X (Twitter), Facebook, LinkedIn, Slack, or Discord, crawler bots automatically extract this image to generate a rich visual link card. A 1200x628 image works seamlessly as both an Open Graph image and a Twitter Card image.
Should I use PNG or JPG?
Use PNG if your Twitter Card includes text headlines, typography, brand logos, vector illustrations, or screenshot UI elements, because PNG preserves sharp edges without blur or lossy compression artifacts. Use JPG if your card is a photograph, scenic background, or complex realistic image, which keeps file size small and ensures quick loading over mobile networks.
Can I upload a larger image?
Yes, you can upload high-resolution images of any size (up to 10MB) into our tool. Our client-side image engine will automatically resize, crop, and fit your image to the exact 1200x628 pixel specification right inside your web browser while preserving optimum clarity and sharpness.
