Video Thumbnail Generator

• Free online video thumbnail generator supporting common formats such as MP4, WebM, AVI, MOV and MKV — everything runs locally in your browser, so your videos are never uploaded
• Capture frames at a fixed time interval or extract a set number evenly across the video, with export format (JPG/PNG/WEBP) and image quality options
• A live progress bar shows the extraction progress, and the video duration and resolution are read automatically
• Every thumbnail is labeled with its time point; download thumbnails individually, click to preview them enlarged, or package and download all of them as a ZIP with one click

1. Open the tool page — no download or installation needed
2. Click the upload area to choose a video file, or drag and drop a video straight into it (up to 500 MB per file)
3. Choose the capture mode (by interval or by count) and set the export format and image quality, then click "Generate Thumbnails" and wait for the progress bar to finish
4. In the results grid, hover over a thumbnail to download it individually, click an image to enlarge and preview it, or click "Download All" to save everything as a ZIP

• This tool is completely free and requires no sign-up
• Everything runs locally in your browser — your videos are never uploaded
