What Are Video Thumbnails Used For?
YouTube & Video Platforms
Custom thumbnails are among the most important factors for click-through rate on YouTube. Extract the best frame from your video to use as a compelling, accurate thumbnail.
Articles & Blog Posts
Embed a sharp still from a video to give readers visual context before they watch. Better than a blurry auto-generated poster frame.
Email Campaigns
Email clients can't embed video directly. Use a thumbnail with a play button overlay to preview the video and link to the hosted version.
Video Archiving
Extract preview thumbnails from a large library of videos to quickly identify content without opening each file.
Frequently Asked Questions
What resolution will my thumbnail be?
By default, the thumbnail matches the original video resolution. You can downscale in the Output Width dropdown if you need a specific size for a platform like YouTube (which recommends 1280×720 for thumbnails).
What size does YouTube recommend for thumbnails?
YouTube recommends 1280×720 pixels (16:9 aspect ratio), JPEG or PNG format, under 2 MB in file size. Select "1280px" in the Output Width dropdown for a YouTube-ready thumbnail.
Can I capture multiple frames at once?
Yes — the "Auto-Generate 9 Thumbnails" button automatically extracts frames at evenly spaced intervals throughout your video, giving you a grid of options to choose from.
Is my video uploaded anywhere?
No. Frame extraction happens entirely within your browser using the HTML5 Canvas API. Your video file never leaves your device.
Frequently Asked Questions
How do I capture a specific frame?
Load your video and use the scrubber or arrow keys to navigate to the exact frame you want. The preview updates in real time. Click "Capture Frame" when you have the right moment.
Can I export multiple frames at once?
Yes — use the "9-Frame Grid" option to automatically capture a spread of frames across the video, useful for creating video preview thumbnails or storyboards.
What resolution will the thumbnail be?
The thumbnail is captured at the video's native resolution. For the highest quality, use the original video file rather than a compressed copy.
Which format should I use — JPG or PNG?
JPG produces smaller files and is suitable for most uses. PNG is lossless and better for images where you need the finest detail or plan to edit the image further.
Are my video files uploaded to a server?
No. All frame extraction happens in your browser using the HTML5 Video API. Your files never leave your device.
