How to Use the Facebook Post Preview Tool

Getting started takes seconds. Enter your page or profile name in the top field, then type (or paste) your post copy into the content area. Watch the mockup on the right update live as you write. Want to test how an image affects your post? Click the upload area or drag a photo straight from your desktop — the preview will render it exactly as Facebook would, filling the full width of the post card. Use the Feeling / Activity dropdown to tag an emotion, toggle the reactions bar on or off, and enter a custom reaction count to simulate social proof. When you're happy with how everything looks, click Screenshot to capture a PNG you can share with your team or client.

Tips for Writing High-Performing Facebook Posts

1

Lead with a Hook in the First Two Lines

Facebook truncates text with a "See More" link after roughly 250 characters. Use the preview to confirm your most compelling sentence sits above that cut-off and grabs the scroll.

2

Use Images to Double Your Reach

Posts with images consistently earn more organic reach than text-only updates. Upload your creative to the previewer to make sure it isn't awkwardly cropped before going live.

3

Keep Captions Short & Scannable

The sweet spot for engagement is typically 40–80 characters. Use the character counter in this tool to keep copy tight and punchy without relying on "See More" to finish the thought.

4

Add Emojis Strategically

One or two well-placed emojis can increase engagement by up to 57%. Use the emoji inserter in the tool to test placement and make sure the post still reads naturally at a glance.

5

End with a Clear Call to Action

Tell readers exactly what to do next — comment, share, click the link, tag a friend. Check the preview to confirm your CTA is visible without needing to expand the post.

6

Use the Feeling Tag for Authenticity

Feeling/Activity tags appear beneath your name in the feed and signal personality. Test different moods in the dropdown to find one that fits your brand voice before posting.

Frequently Asked Questions

Is this Facebook post preview tool free?
Yes — completely free, forever. No account, no credit card, no watermarks. Just open the tool, compose your post, and preview.
Does this tool post to Facebook for me?
No. This is a simulation tool only. It shows you how your content will look without connecting to Facebook's API. You'll still need to copy your text and upload your image inside Facebook when you're ready to publish.
What image sizes work best for Facebook posts?
For a standard shared image, Facebook recommends 1200 × 630 px (roughly 1.91:1 ratio). For square posts use 1080 × 1080 px. Upload either size to the previewer and you'll see exactly how it fits the feed card at desktop resolution.
How many characters can a Facebook post contain?
Facebook allows up to 63,206 characters per post. However, the feed shows only around 250 characters before hiding the rest behind a "See More" link. The character counter in this tool tracks both limits in real time.
Can I preview link cards or shared URLs?
Link card previews depend on the Open Graph metadata of the destination URL, which can only be fetched live. For an accurate link-card preview, use Facebook's own Sharing Debugger at developers.facebook.com/tools/debug. This tool focuses on text + image post formats.
Does the screenshot feature upload my image anywhere?
No. Everything runs entirely in your browser. Images are processed locally using the FileReader API and canvas. Nothing is sent to any server — your content stays private.
