Perfect HD thumbnails for YouTube. Processed securely and never stored.
YouTube recommends 1280×720 px (HD, 16:9 aspect ratio) for custom video thumbnails. The minimum size is 640×360 px, and the maximum file size is 2 MB. Supported formats are JPEG, PNG, GIF, and WebP. Thumbnails appear in search results, suggested videos, the YouTube homepage, and your channel page — uploading at 1280×720 ensures sharpness across all placements.
The most effective YouTube thumbnails use high contrast, bold text (readable at small sizes), a clear focal point (face, product, or graphic), and a consistent brand style. At 1280×720 px, you have enough resolution to include all these elements sharply. Thumbnails with faces showing emotion consistently outperform generic graphics.
The thumbnail (1280×720 px) is the image shown before a viewer clicks play — it appears in search, suggested videos, and the channel page. It is different from the end screen, banner, or Shorts thumbnail. YouTube Shorts thumbnails are displayed at a 9:16 vertical ratio (1080×1920 px) — use our Instagram Story Resizer for that format.
Images are processed on our server and deleted immediately after your download. We never store, index, or share your files.
