About Infinity Tools
Last updated · By Infinity Tools
Infinity Tools is a growing collection of free, fast, privacy-friendly online tools — built to help creators, researchers, students and everyday people get things done without friction. Every tool runs in your web browser, with no account to create.
What we build
Each Infinity tool does one job well. Today three tools are live:
- YouTube Thumbnail Downloader — paste a YouTube link and download the video's thumbnail in every available resolution, with insights drawn from public data.
- YouTube Storyboard Downloader — see every preview frame YouTube makes for a video, with timestamps, and download single frames, a ZIP or a contact sheet.
- Sleep Calculator — find the best time to go to bed or wake up, based on 90-minute sleep cycles, with modes for college students, shift workers and naps.
More tools are on the way, from calculators and converters to writing and image tools. You can see the full list on the Infinity Tools homepage.
Why we built it
Most simple online tools are slow, cluttered with pop-ups, or hidden behind sign-ups and paywalls. We wanted tools that load quickly, respect your privacy, work on any device, and are free to use.
Our principles
- Free to use. Every tool is free, with no account needed.
- Private by default. The tools run in your browser. We don't ask for personal information, and the sleep calculator never sends your times anywhere. See the Privacy Policy for the details for each tool.
- Honest and useful. Explanations are written in plain language, and health facts link to their sources.
- Works everywhere. Every page is built to work smoothly on phones, tablets and desktops. The YouTube tool and the sleep calculator are available in 7 languages.
Independence
Infinity Tools is an independent project. It is not affiliated with, endorsed by, or sponsored by YouTube, Google LLC or any other company whose services our tools work with. Trademarks belong to their respective owners. The sleep calculator offers general guidance only and is not medical advice.
