How it works
- 1Drop your image in — a photo, a designed card or a screenshot.
- 2It is scaled and center-cropped to 1200 × 630, the 1.91:1 ratio used by shared images and link previews.
- 3If the image is for an og:image tag, keep any text well inside the frame — previews are rendered small in feeds and chat apps.
Frequently asked questions
- Is 1200 × 630 only for Facebook?
- No, and that is what makes it worth using. The 1.91:1 shape is the Open Graph convention, so the same file serves link previews on Facebook, LinkedIn, Slack, WhatsApp, Discord and most chat clients. One export covers nearly every place a link to your page will be pasted.
- Why does my link preview show a cropped or blank image?
- Usually because the source is the wrong shape or too small. Preview renderers crop to 1.91:1 and many ignore images below roughly 600 × 315, falling back to nothing. Supplying an image already at 1200 × 630 removes both failure modes.
- My preview still shows the old image after I changed it.
- Facebook caches what it scraped the first time. Changing the file does not clear that cache; you need to re-scrape the URL with their sharing debugger. This is a caching issue rather than an image issue — the new file is correct, the preview is stale.
- Should text go in a share image?
- Sparingly. Previews render small in feeds and very small in chat apps, so a headline of a few words works and a paragraph does not. Keep whatever text you use away from the edges, since some clients crop the card slightly differently.
About this tool
1200 × 630 is the most portable image size on the web. The 1.91:1 shape comes from the Open Graph specification rather than from Facebook alone, which means one file works as a shared post, a Facebook link preview, and the card that appears when your URL is pasted into LinkedIn, Slack, WhatsApp or Discord. Preparing a single image at this size covers nearly every context a link travels through.
Link previews fail in two predictable ways, and both are fixed at the source. An image of the wrong aspect ratio gets cropped by the renderer, often through the middle of a headline; an image below roughly 600 × 315 is ignored entirely by some clients, leaving a card with no picture at all. Supplying 1200 × 630 satisfies the minimum with margin and matches the crop exactly.
One thing this tool cannot fix is caching. Facebook stores what it scraped the first time your URL was shared, so a corrected image will not appear until the URL is re-scraped through their sharing debugger. The image itself is handled here — scaled to fill, cropped evenly from the centre, compressed — entirely inside your browser, with nothing uploaded and your original untouched.
