LinkedIn Image Sizes — Built-In Presets

SnapMock includes the exact LinkedIn-recommended dimensions as one-click presets:

📐 LinkedIn Post — 1200 × 627 px

The recommended image size for LinkedIn feed posts. Displays full-width without cropping on both desktop and mobile.

📐 OG Image / Link Preview — 1200 × 630 px

When someone shares a link to your site on LinkedIn, this is the image that appears. Set it as your page's OG image.

📐 Square Post — 1080 × 1080 px

Square images get great engagement on LinkedIn and can be cross-posted to Instagram and Twitter.

Why LinkedIn Posts With Mockups Get More Engagement

LinkedIn's algorithm favors posts with images — they get 2× more engagement than text-only posts. But a raw screenshot looks amateurish. A polished mockup with a device frame and gradient background looks professional and signals quality.

💡 Pro Tip: Use SnapMock's MacBook Pro or browser chrome frame for B2B/SaaS screenshots, and iPhone frames for mobile app announcements. The device context instantly communicates what your product is.

FAQ

What size should LinkedIn post images be?
LinkedIn recommends 1200×627 px for feed posts. For shared links (OG images), use 1200×630 px. SnapMock has both as built-in presets.

Does LinkedIn compress images?
Yes. Exporting at 2× resolution (available in SnapMock) helps maintain sharpness after LinkedIn's compression.

Can I use SnapMock for LinkedIn company pages?
Absolutely. The images are yours — use them for personal posts, company pages, articles, or ads.

Is this better than Canva for LinkedIn images?
For screenshot mockups, yes. Canva requires an account and doesn't have device frames. SnapMock is purpose-built for turning screenshots into polished mockups — no signup needed.
