Frequently Asked Questions about YouTube Thumbnail Resizer (1280×720 px HD 16:9, ≤2 MB)
Why does YouTube Studio reject my 1920×1080 PNG thumbnail?
YouTube enforces a strict 2 MB (2,048 KB) file size cap on custom thumbnails. High-detail 1920×1080 PNGs frequently exceed 3–6 MB. Resizing to YouTube's official 1280 × 720 px resolution and exporting as JPEG reduces the file size to ~150–350 KB while looking identical on screen.
What is the official YouTube thumbnail resolution and aspect ratio?
Google's official YouTube Help documentation specifies a resolution of 1280 × 720 pixels (with a minimum width of 640 pixels) in a 16:9 widescreen aspect ratio.
Does YouTube accept WebP thumbnails?
YouTube Studio officially supports `.JPG`, `.PNG`, and `.GIF` uploads. That is why our YouTube Thumbnail Resizer pre-selects `JPEG` by default for universal YouTube Studio compatibility.
Are my unpublished video thumbnails uploaded to any server?
Never. All image resizing runs 100% locally inside your browser tab.
