WebP is the modern web image format, noticeably lighter than JPG at a similar quality. This tool takes the first frame of each video you add and saves it as a WebP, at the full resolution of the video, without uploading anything.
How to get a video thumbnail as WebP
- Drop your videos in the box above, or click to pick them. You can add as many as you like.
- WebP is already selected as the output format. Switch on other formats if you want them too.
- Optional: open Advanced Settings to resize the thumbnail by percentage, width or height, and add more sizes.
- Click Extract Thumbnails, then download each image or all of them at once. Nothing is uploaded: everything runs in your browser.
Why save video thumbnails as WebP?
For a poster image on a website, WebP gives you a sharp thumbnail that loads fast, and every modern browser displays it.
Frequently asked questions
Can I use a WebP thumbnail as a video poster?
Yes. The poster attribute of the HTML video element accepts any image the browser can display, and all modern browsers display WebP.
Which videos can I use?
MP4, WebM, MOV, MKV and any other video your browser can decode. You can mix formats in the same batch and get one image per video.
Are my videos uploaded?
No. The first frame is decoded and saved as an image in your browser, on your device. Your videos are never sent to a server, so this works for private files too.
