Thumbnail & Public Video Downloader

什麼是 Thumbnail & Public Video Downloader？

Thumbnail Grabber is a free web toolkit I built for two everyday problems: saving thumbnails and public media from social and video links, and converting iPhone HEIC photos to JPG, PNG, WebP, or PDF. Paste a URL on the homepage, pick a platform, and download what is available. YouTube has its own page for cover images, optional subtitles, and basic video details. The HEIC tool supports batch uploads and merged PDFs. No signup required.
