MOV is the QuickTime format used by iPhones, Macs and many cameras. AVIF is the newest widely supported image format and gives the smallest files. This tool takes the first frame of each MOV video and saves it as an AVIF, without uploading anything.
How to extract an AVIF thumbnail from MOV
- Drop your MOV 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 MOV thumbnails as AVIF?
Getting a still from an iPhone or camera clip is handy for a cover photo, a social post or a quick preview, without opening a video editor. 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
Can I use iPhone videos?
Yes, on most devices. iPhone MOV files use H.264 or HEVC. HEVC decoding depends on your browser and hardware: it works in Safari, and in Chrome or Edge on devices with HEVC support. ProRes MOV files from professional cameras cannot be read by browsers.
Do all browsers display AVIF?
All current versions of Chrome, Edge, Firefox and Safari display AVIF. For older browsers, also export a JPG.
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.
