Share Link Generator

Unsupported input

The tool may reject input that does not match the expected content, structure, or file type.

Fix: Confirm the tool input requirements and paste the correct type of data.

Incomplete values

Missing fields or partial content can block processing or produce weak results.

Fix: Provide the full required input before running the tool.

Copying placeholder content

Sample or placeholder values can lead to output that looks valid but is not ready for real use.

Fix: Replace placeholders with your actual values before relying on the result.

How long does a platform cache a share preview?

Most platforms cache OG/Twitter Card data for 24–72 hours. If you update tags after sharing, use the platform's debugger (Facebook Sharing Debugger, X Card Validator, LinkedIn Post Inspector) to force a refresh.

Does Share Link Generator work offline after the page loads?

Yes. Preview rendering and image generation are client-side, so pasted copy and uploaded assets never leave your device.

What image dimensions does Share Link Generator recommend?

Share Link Generator follows the platform's current published specs: 1200×630 for OpenGraph (Facebook, LinkedIn, WhatsApp), 1200×600 for X (Twitter) summary-large-image, 1080×1080 for Instagram feed. The UI shows the target ratio with a crop preview before you export.

How accurate is the preview in Share Link Generator?

Share Link Generator renders the same field lengths and truncation rules the real platforms use as of their latest public API docs. Exact pixel layout can still drift between platform updates, so treat the preview as representative, not pixel-perfect.

Does Share Link Generator fetch the live preview from the platform?

No. Share Link Generator renders the preview locally from the OpenGraph/Twitter Card tags you provide, which is why there's no rate limit and your URL isn't shared with anyone.
