Why does Facebook show a different image than mine?

Facebook picks the first image that meets the minimum dimensions (200x200) if no og:image tag is set. Our tool highlights your actual og:image so you see exactly what FB will use.

What are the ideal image dimensions for Facebook?

Use 1200x630 pixels (1.91:1 aspect ratio). Images under 600x315 get downgraded to small thumbnails; images over 5MB get skipped entirely.

My changes do not show up on Facebook — why?

Facebook caches link previews for 30 days. Use the official Sharing Debugger at developers.facebook.com/tools/debug after our preview to force a re-scrape.

What is the maximum title length?

Facebook truncates at ~60 characters on mobile and ~88 on desktop. Our preview simulates the mobile cutoff so you catch truncation early.

What is the maximum description length?

About 110 characters on mobile, 200 on desktop. After that Facebook adds an ellipsis. Sometimes FB hides the description entirely on mobile — so lead with the title.

Does this tool actually fetch my live OG tags?

Yes. We server-side fetch your URL, parse the <meta property="og:*"> tags, and populate the preview. If fetch fails (CSP, auth wall, 4xx), fill the fields manually.

Can I preview a staging or localhost URL?

Only if it is publicly reachable. For localhost, use a tunnel like ngrok or Cloudflare Tunnel to expose your preview URL first.

Does Facebook respect all 20+ OG tags?

It respects og:title, og:description, og:image, og:url, og:type, og:site_name and (for video) og:video. The rest (og:locale, og:image:width) are optional hints.

Why is my preview card a small square instead of wide?

Small square = Facebook could not find an image meeting 600x315 minimum. Upload a wider hero image or set og:image:width and og:image:height explicitly.

Does the tool support Facebook carousel ads or catalogues?

No — this previews organic link shares only. For ad creatives, use Meta’s Ads Manager preview tools.

Is my URL logged or stored anywhere?

The fetch is stateless. We pass the URL to our endpoint, scrape tags, return them, and forget. No database, no analytics, no tracking pixel.

Yes. No sign-up, no rate limit on typical use, no watermark. Grigora monetises through its paid SEO platform — these tools are free forever.

What is the Facebook Share Preview?

It's a live OG-tag debugger that pulls your page's <meta> tags, renders Facebook's exact news-feed card, and lets you edit title, description and image to test variations before you publish.

Unlike Facebook's own Sharing Debugger (which requires login and doesn't let you edit), this tool works in 2 clicks — so you catch truncation, grey-box images and missing descriptions before they tank your CTR.

How to preview a Facebook share in 5 steps

Paste your URL

Drop any public URL into the input field. No auth required.

Click Fetch

We scrape og:title, og:description, og:image and fill the preview in under a second.

Review the card

Check the mobile news-feed simulation. Look for truncation, missing image or grey boxes.

Edit to test variations

Tweak title, description and image URL live. Pick the version that gets the best feed eye-test.

Ship & bust cache

Deploy the new OG tags and run the URL through Facebook's Sharing Debugger to flush FB's 30-day cache.

Who this tool is for

Six real-world jobs-to-be-done the preview solves best.

Content marketer

Scenario: Publishing a blog post for Facebook distribution.

Result: Tweaks title + description in-tool, catches that the headline got truncated, rewrites to fit 60 chars.

E-commerce store

Scenario: Launching a product page.

Result: Spots that the product shot is 800x400 (small card). Uploads a 1200x630 lifestyle shot, CTR jumps 2.4x.

SaaS founder

Scenario: Prepping a landing page for a launch day Facebook ad.

Result: Confirms OG tags are live + valid before the campaign, avoids the classic "broken preview on launch" disaster.

Agency team

Scenario: Auditing 40 client sites for social hygiene.

Result: Pastes each URL, exports findings. Surfaces missing og:image on 18/40 sites in under 20 minutes.

Publisher / blogger

Scenario: Competing for feed attention.

Result: Tests 3 title variations in-tool before publishing, picks the one with clearest hook under 60 chars.

WordPress developer

Scenario: Debugging why Yoast OG tags are not kicking in.

Result: Tool fetches live — shows WP is still serving old cached HTML. Flushes CDN cache, issue fixed.

Content-type specific guides

OG tag strategy depends on what kind of page you're sharing. Here are 5 cheat sheets.

For blog posts

Title under 60 chars, description under 110. Hero image 1200x630 with text burned in often outperforms pure photography in feed.

For product pages

Skip the lifestyle shot on mobile. Use the plain product on white for recognition, save lifestyle for carousel ads.

For landing pages

Match the Facebook ad creative to the OG image. Inconsistency between ad and organic share kills trust.

For video / podcast episodes

Set og:type=video.other and og:video to enable in-feed playback. Still upload a strong og:image as fallback.

For SaaS / software

Lead with a feature screenshot, not a logo. Facebook rewards "thumb-stopping" visuals, not branding.

8 preview bugs and how to fix them

× Image shows as a grey box

Fix: og:image must be an absolute URL on HTTPS. Relative paths like /hero.jpg get stripped by Facebook.

× Title cut off at "..."

Fix: Mobile shows ~60 chars. Move your brand name to the end or remove it entirely — FB already shows the domain.

× Description missing entirely

Fix: Add og:description explicitly. Facebook does NOT fall back to meta description anymore as of late 2024.

× Preview shows an old image

Fix: Facebook caches for ~30 days. Run the URL through the official FB Sharing Debugger and click "Scrape Again".

× Domain shows wrong casing

Fix: Facebook always uppercases the domain in the card (EXAMPLE.COM). That is cosmetic, not a tag bug.

× Video thumbnail instead of image

Fix: If og:video is set, FB may ignore og:image. Remove og:video or set og:type=website to force image display.

× "Warning: The URL returned HTTP 4xx"

Fix: Your page blocks Facebook's crawler. Add facebookexternalhit/1.1 to your allow-list in robots.txt or WAF rules.

× Image orientation flipped

Fix: Facebook sometimes ignores EXIF rotation. Re-save the image with the correct orientation baked in and use a tool like ImageMagick to strip EXIF.

How long Facebook caches your OG tags before a re-scrape

Why Facebook preview hygiene still matters in 2026

Feed CTR compounds

A clean 1200x630 hero + tight 60-char title routinely doubles CTR vs. a broken grey-box card. That lift is pure free traffic, every single share.

Credibility on first impression

A missing image or EXAMPLE.COM title signals “rushed” or “spam” before a user even reads. Broken previews lose trust in a 200-millisecond feed scroll.

Facebook caches for 30 days

Once FB sees a broken preview, it is stuck there for a month. Preview first, publish second — or live with the bad card for 30 days.

Cross-channel impact

The same OG tags drive LinkedIn, Slack, WhatsApp and iMessage link cards. Fix it here, you fix it everywhere at once.
