Question 2

Do I need to create an account?

Accepted Answer

No account or signup is required. Open the page, upload a video, and download your thumbnail instantly.

Question 3

Is my video uploaded to a server?

Accepted Answer

No. All video processing happens locally in your browser using the Canvas API. Your file never leaves your device.

Question 4

What video formats are supported?

Accepted Answer

MP4, WebM, MOV, AVI, and MKV are supported in most modern browsers. MP4 (H.264) offers the best compatibility.

Question 5

Can I use a YouTube or Vimeo link?

Accepted Answer

No. YouTube and Vimeo page links are not supported — the browser cannot read those directly. Upload the MP4 file, or paste a direct link to a .mp4 file (e.g. https://yoursite.com/video.mp4).

Question 6

What size should a YouTube thumbnail be?

Accepted Answer

YouTube recommends 1280×720 pixels (16:9 aspect ratio), JPG or PNG, under 2 MB. Choose the HD preset when exporting for YouTube.
