JPEG, PNG, WebP, AVIF, HEIC. All processing stays in your browser.
If your image is smaller than 1200×628 pixels, the tool will upscale it and show a warning before download. Keep important text and faces within the centre area, since some platforms crop the outer edges of link preview images slightly.
1200x628 at a 1.91:1 ratio is the closest thing the web has to a universal link preview size, working across nearly every major platform that reads Open Graph tags.
Facebook and LinkedIn link previews
Set as the og:image on your page so shared links display a clean, correctly cropped preview card.
X (Twitter) summary cards
Used for the large summary card format that displays a wide image above the tweet text.
Reddit and Slack previews
Both platforms read the same og:image tag, so one image covers these contexts as well.
Blog and article featured images
Many blog themes use the same image for both the on-page header and the social share preview.
Setting up a full website hero image too? Resize for Website covers hero banners, blog featured images and backgrounds alongside this Open Graph size.
Platforms don't refetch a page's og:image every time someone shares the link. They cache whatever their crawler bot saw the first time your page was posted. If you update the image later, anyone who already shared or previewed that link will keep seeing the old cached version until you force a re-crawl through the platform's own debugging tool, such as Facebook's Sharing Debugger, LinkedIn's Post Inspector, or X's Card Validator.
The URL in your og:image tag needs to be a full, absolute HTTPS address that's publicly reachable without any login, and not blocked by robots.txt for that platform's crawler. A relative path, or an image sitting behind authentication, fails silently, the crawler simply gives up and no preview card appears at all, rather than showing an error you'd notice right away.
Elsewhere on a modern site, WebP or AVIF is usually the better default. For the og:image specifically, the crawler bots these platforms use to scrape link previews sometimes lag behind consumer browsers in format support, so JPEG or PNG remains the safest choice for this one image even on a site that otherwise serves WebP or AVIF everywhere else.
Most platforms cap the size of the image their crawler will fetch, typically a few megabytes, and a slow-loading image can cause the crawl to time out before a preview ever gets generated. A JPEG in the few hundred kilobyte range at 1200x628 loads quickly enough to avoid that entirely, without any visible quality loss at the size a preview card actually displays.
1200x628 pixels gives a 1.91:1 aspect ratio, which is the size most platforms expect for the og:image tag used to generate link preview cards. Facebook, LinkedIn, X, Reddit, Slack and Discord all read this same tag, so a single 1200x628 image works as the preview image across nearly every platform when someone shares your page link.
If your image is smaller than 1200x628 pixels, this tool will upscale it to fit and show a warning before download. For link preview images, text and logos that are upscaled can look soft. For the sharpest result, design or start from artwork that is at least 1200 pixels wide, and keep important text and faces within the centre 1080x600 area, since some platforms crop the outer edges slightly.
Both sizes are used interchangeably across guides and platforms, and the 2 pixel difference in height has no visible impact. 1200x628 is the size most commonly cited for Facebook, LinkedIn and Reddit link previews, while 1200x630 is also widely recommended as a general Open Graph default. Either size will display correctly, since platforms crop and scale these images to fit their own preview card dimensions.
