Frequently Asked Questions

Is FrameSnap really free?

Yes. FrameSnap is 100% free with no hidden fees, no premium tier, and no watermark on exported images.

Do I need to create an account?

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

Is my video uploaded to a server?

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

What video formats are supported?

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

Can I use a YouTube or Vimeo link?

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).

What size should a YouTube thumbnail be?

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