How to Use Our Free Online Twitch Thumbnail Resizer

  1. Upload your image: Click "Choose PNG, GIF, JPG, or WebP file" and select your thumbnail image. We support PNG, GIF, JPG, and WebP formats.
  2. Choose output preset: Select "VOD Thumbnail - 1280×720" (minimum required size) or "HD - 1920×1080" (higher quality option).
  3. Choose output format: Select JPG (recommended for smaller file size) or PNG (for crisp text and graphics).
  4. Select fit method: Choose "Fill (Crop)" for best-looking results with drag reposition and zoom controls, or "Fit (Pad)" to fit the whole image with padding.
  5. Adjust crop (if using fill mode): Drag the image to reposition and use the zoom slider to adjust the crop area. Use "Reset Crop" to start over. Enable "Show Title-Safe Area" to keep important text away from edges.
  6. Set quality (if using JPG): Adjust the quality slider (60-95%) to balance file size and image quality. Lower values create smaller files, higher values preserve more detail.
  7. Resize: Click "Resize Thumbnail" to automatically generate your 16:9 thumbnail at the selected size.
  8. Preview and download: Review your resized thumbnail at actual size and use the zoomed preview to inspect details. Download your thumbnail and upload it to your Twitch VOD or highlight.
