Image hosting for LinkedIn consistent cards, fast delivery.
LinkedIn uploads images to its own CDN when you post. For articles you cross-post, external-site link cards, newsletter issues, and sales-enablement assets, external hosting gives you control and consistency.
Upload an image →Why hosting matters on LinkedIn
Link-card og:image
When you share your own site's URL on LinkedIn, the preview card pulls og:image. That asset needs to be on a fast, always-up CDN — LinkedIn caches the first fetch.
LinkedIn Article cross-posting
Same article on your site + LinkedIn Articles. Use identical ImageToURL URLs in both, and you keep one source of truth.
Company page branding
Banner, logo, and cover variants reused across posts, articles, and ads. Host once, reference many.
Sales enablement
Pitch decks, one-pagers, case-study PDFs referenced via URL in Sales Navigator messages — all need external hosting.
How to embed
Upload your assets
Drop logos, banners, article images — get CDN URLs.
Wire into og:image on your pages
LinkedIn's card scraper reads og:image and og:title. Point it at your ImageToURL URL.
Post Inspector verify
Use LinkedIn's Post Inspector (linkedin.com/post-inspector) to refresh the card cache after any og:image change.
FAQ
Does LinkedIn render external images in posts?
LinkedIn always re-hosts uploads. What it renders externally is the link preview card, which fetches og:image from the target URL. That's where ImageToURL plugs in.
What's the best link-card image size?
1200×627 for the big card. LinkedIn crops anything else. Use the image resizer to hit that exactly.
How long does LinkedIn cache og:image?
Days to weeks. Use Post Inspector to force a recache after changing the image. Otherwise people sharing your link see the old one.
Can I animate the card image?
No — LinkedIn's link-preview scraper captures a static image. For animation, post native video.
LinkedIn Newsletter cover art?
Uploaded natively, not from URL. Keep the high-res source on ImageToURL for reuploads.
Does it support LinkedIn Learning course thumbnails?
Course images are uploaded in Learning Hub. Use ImageToURL to keep the pre-upload source and any video still-frames.
How to avoid LinkedIn compressing my images?
For post uploads, compression is forced. For link-card og:image, LinkedIn doesn't re-compress — your uploaded JPG/PNG is what users see. Pre-optimize with the image compressor tool.
Max size?
og:image: 5 MB is a safe ceiling for LinkedIn's scraper. ImageToURL's free 10 MB cap is plenty; heavily compress before upload.
