Frequently asked questions
What is Open Graph?
Open Graph is a protocol developed by Facebook that defines how web pages are represented when shared on social media. The og:title, og:description, og:image, and og:url tags are the core elements.
Why do I need Open Graph tags?
Without them, social platforms pull arbitrary content from your page, often the wrong title, a missing image, or an irrelevant description. Open Graph gives you control over how your content appears when shared.
What image size should I use for og:image?
1200 by 630 pixels is the recommended size for Facebook and LinkedIn. Twitter uses 1200 by 600 pixels. A 1200 by 630 image works well across all major platforms.
Can I preview how my page will look when shared?
Yes. The tool shows a preview of how your page will appear in a social media post after you fill in the tag values.
Do I need different tags for Twitter?
Twitter uses its own twitter:card, twitter:title, and twitter:description tags. The Open Graph generator includes Twitter card tags alongside standard og tags.
Does it work offline?
Yes.
Is Open Graph Generator Free free to use?
Open Graph Generator Free is completely free with no subscription, no trial period, and no credit card required. There are no usage limits, watermarks, or premium tiers. The tool is funded by the existence of the wider OnlineToolsPlus platform rather than by charging users for individual tools.
Does Open Graph Generator Free work on mobile devices?
Yes. Open Graph Generator Free works on any modern smartphone or tablet — iPhone, iPad, Android phones and tablets. Open it in Safari, Chrome, or Firefox on your device and it functions identically to the desktop version. The interface is responsive and adjusts to smaller screens automatically.
Do I need to install anything to use Open Graph Generator Free?
No installation is required. Open Graph Generator Free runs entirely in your web browser. Open the page and start using it immediately. There is no app to download, no browser extension to install, and no account to create. It works on Windows, macOS, Linux, iOS, and Android — any device with a modern browser.
Is my data private when using Open Graph Generator Free?
Yes. All processing happens locally in your browser. No data you enter — text, files, or settings — is sent to any server or stored anywhere outside your device. OnlineToolsPlus has no server-side processing for this tool. Your data is as private as anything else on your device.
- Sensitive documents stay private. Contracts, financial statements, personal photos, and medical records never leave your device.
- No account required. There is nothing to sign up for, no password to manage, and no personal information collected.
- No usage limits or rate limits. Browser-based tools are not throttled by server capacity. You can use the tool as many times as needed.
- Works offline (after first load). Once the page is loaded, most functionality works without an active internet connection.
This matters for several reasons:
Open Graph Generator Free on OnlineToolsPlus runs entirely in your browser. No file, text, or data you enter is ever sent to any server. Processing uses the JavaScript APIs built into your browser — the same environment used by banking and healthcare applications.
