Frequently Asked Questions
Quick answers to common questions about our YouTube tools
How do I get the transcript of a YouTube video?
Use our free YouTube Transcript Generator: paste the video URL, click "Generate Transcript", and get the full text with timestamps. You can export to SRT, VTT, TXT, or other formats. It works with auto-generated captions and supports 100+ languages.
What is a YouTube transcript and how is it different from subtitles?
A YouTube transcript is a text document of all spoken words in a video with timestamps. Subtitles are timed text displayed over video during playback. Our tool extracts subtitles/captions and converts them into downloadable transcript files you can search, copy, and reference offline.
What is the YouTube thumbnail size?
The recommended YouTube thumbnail size is 1280×720 pixels (HD, called "maxresdefault"). YouTube also generates smaller versions: sddefault (640×480), hqdefault (480×360), mqdefault (320×180), and default (120×90). Our downloader lets you download all available sizes.
How do I download a YouTube thumbnail?
Paste any YouTube video URL into our Thumbnail Downloader, click "Get Thumbnails", and download in your preferred size. We show all available resolutions from HD (1280×720) to default (120×90), plus channel banners and profile pictures.
