Frequently asked questions
What is the optimal size for OpenGraph social preview images?
The universal standard is 1200 × 630 pixels with a 1.91:1 aspect ratio. This ensures high-resolution rendering without letterboxing on Twitter, LinkedIn, Facebook, and Discord.
Why are my social preview cards getting truncated on mobile?
Mobile chat apps like WhatsApp and iMessage often truncate descriptions longer than 125 characters. Keep titles under 60 characters and descriptions between 100 and 125 characters.
Is my data or unreleased website URL stored on PolyForge servers?
No. All editing, canvas image rendering, and preview simulations execute 100% locally in your browser. Live URL scans are processed in-memory and never logged or stored.
