Free Video Tools
Everything BlackHole can do beyond downloading — transcripts, subtitles, thumbnails, clips, and QR codes. All free.
YouTube Transcript Extractor
Paste a link, get the full transcript as clean text. Copy it free or feed it to ChatGPT.
Subtitle Downloader
Save any YouTube video's captions as SRT, VTT, or TXT — every language, auto-generated included.
Thumbnail Downloader
Grab any video's thumbnail in every size YouTube has, up to HD 1280×720, straight to JPG.
YouTube Thumbnail Tester
Preview your thumbnail in realistic home and search layouts — light/dark, desktop/mobile — before you publish.
Playlist Length Calculator
How long is that playlist? Total watch time, average video length, and durations at up to 2× speed.
Subtitle Converter
Convert SRT ⇄ VTT or strip either to plain text — runs entirely in your browser, files never uploaded.
YouTube Video Clipper
Cut the exact segment you need from a YouTube video and download just that clip.
Video QR Code Generator
Turn any video URL into a styled QR code and download it as PNG or SVG for print or slides.
Video Downloader
The main event: download videos from YouTube, TikTok, Instagram, X, and more platforms.
Which tool do you need?
You want the words from a video. If you want to read them, paste them into an AI chat, or quote them, use the transcript extractor. It gives you clean plain text with the timestamps stripped, and copying needs no account. If you want a subtitle file that a video editor or player can load, with timings intact, use the subtitle downloader instead. Same source captions, different output.
You already have a subtitle file. The subtitle converter turns SRT into VTT or either into plain text, and it runs entirely in your browser — the file is never uploaded anywhere, which matters if the content is not yours to share.
You want the picture, not the video. The thumbnail downloader pulls the existing thumbnail at every size YouTube stores. If you are designing your own and want to see how it will look in the feed before you publish, that is the thumbnail tester.
You want part of a video, or none of it. The video clipper downloads just the segment you mark, instead of the whole file. The playlist length calculator tells you what you are committing to before you start, including the runtime at 1.5× and 2×. And the QR code generator turns a video link into something you can put on a slide or a printed page.
Everything above works on any operating system, because it all runs in the browser. If you would rather download in bulk from your own machine, that is what BlackHole Desktop is for.
