FAQs

  • Which thumbnail sizes are included?
    YouTube (1280×720 + 1920×1080), YouTube Shorts 1080×1920, TikTok 1080×1920, Instagram square/portrait/tall/landscape/stories, Facebook link/video/square, and X (Twitter) large & summary cards are all covered. We keep the catalog current as platforms update guidance.
  • What do the safe-area guides represent?
    Guides show conservative margins (≈8% horizontal, 8–16% vertical depending on platform) so titles stay legible behind UI chrome, timestamps, and feed overlays.
  • Can I preview the platform UI?
    Yes. Toggle "Show platform overlay" to see stylized UI previews that approximate where platform elements typically appear. These are visual guides—actual UIs vary by device and version. The safe-area guides show accurate measurements.
  • How do I export with transparency?
    Switch the background option to “Transparent (PNG)” and export as PNG. JPG exports will automatically flatten the background to white.
  • Is my artwork compressed?
    PNG exports stay lossless. JPG exports respect the quality slider (default 90%). Choose PNG if you plan to composite later.
  • Does my image ever leave this page?
    No. Uploads, positioning, and exports are processed locally in your browser—nothing is sent to any server.
