AVIF is the newest widely supported image format and gives the smallest files. This tool takes the first frame of each video you add and saves it as an AVIF, at the full resolution of the video, without uploading anything.
How to get a video thumbnail as AVIF
- Drop your videos in the box above, or click to pick them. You can add as many as you like.
- AVIF 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 AVIF?
AVIF is ideal when every kilobyte counts, such as a page with many video previews. Encoding takes a little longer than JPG or WebP.
Frequently asked questions
Do all browsers display AVIF?
All current versions of Chrome, Edge, Firefox and Safari display AVIF. For older browsers, also export a JPG.
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.
