# KeepCopy

> A local-first desktop video downloader for macOS, Windows, and Linux. Paste a link, pick quality in plain language, and save a file to a folder on this computer. The engine is official yt-dlp plus ffmpeg.

This site is the public product and documentation surface. The running desktop app never contacts this marketing site. There is no cloud converter: a pasted URL goes from the user's computer to the video host.

Every HTML page has a Markdown sibling. Append `.md` to the path (`/privacy.md`, `/blog/{slug}.md`, `/blog/category/{slug}.md`, `/changelog.md`). The homepage is [`/index.md`](https://keepcopy.app/index.md).

## Product

- [What stays on your computer](https://keepcopy.app/blog/what-stays-on-your-computer.md): The desktop app sends no telemetry. Your pasted link never goes through our servers. Here is the exact network story, including this website.
- [yt-dlp without the terminal](https://keepcopy.app/blog/yt-dlp-without-the-terminal.md): You do not need a package manager, a PATH setup, or a copied command. Paste a link, pick quality in plain language, and let the app run yt-dlp for you.
- [Downloaded MP4 no audio](https://keepcopy.app/blog/downloaded-mp4-no-audio.md): Your downloaded MP4 has no audio because the host split video and sound. Pick 1080p or 4K in KeepCopy — ffmpeg joins them into one file on this computer.
