# tugpic

> tugpic is a free, open-source (MIT) Chrome extension for downloading images and videos from any web page. Hold a shortcut (Alt / Option by default) and left-click the media: the file is saved to Downloads with no right-click menu and no "Save image as" dialog. It also downloads HLS/DASH streams and blob: videos, every image in an article at once, the videos inside a linked post, and it records live streams in the background.

- Price: free. No account, no server, no analytics, no remote code, zero runtime dependencies.
- Store name: "tugpic - Image & Video Downloader" (Korean: "tugpic - 이미지·영상 다운로더")
- Developer: rootbly team

## What it does

- **Shortcut + left-click saves the media under the cursor.** It looks for `<img>`, `<video>`, a link to media, `<canvas>`, then a CSS background image, in that order, and takes the largest candidate from `srcset` / `<picture>`. The shortcut can be rebound from the popup to any modifier (Alt, Ctrl, Shift, Cmd) or an ordinary key such as D.
- **Streaming video (HLS `.m3u8`, DASH `.mpd`).** Play the video for a moment, then shortcut-click it: tugpic retraces the manifest the page already fetched, downloads the highest-quality segments and joins them into one file. Separate fMP4 video and audio are merged.
- **blob: videos of any size.** A whole-file blob is saved from inside the page, so there is no size limit.
- **Videos from a linked post.** Shortcut-click a post title in a feed; tugpic uses the video addresses already in the list, or reads the post's HTML in memory (no tab opens, no script runs) and saves the videos.
- **Paste an address on the landing page.** The box at https://tugpic.rootbly.com/#url takes the address of a post with a video, a video file or an HLS/DASH manifest and hands it to the extension in your Chrome, which saves the video (or records it when it is live). No server is involved, so the extension must be installed in that Chrome.
- **Whole-article album.** Alt+Shift+D, or the toolbar popup, gathers the body images of the page as thumbnails; untick what you don't want and download the rest into `Downloads/tugpic/<page title>/`. One click on Undo deletes the batch.

## Live stream recording

Shortcut-clicking a live video starts a recording instead of a download.

- Live HLS and live DASH are recorded as the original segments, HTTP-FLV (flv.js / mpegts.js players) as the original bytes. Video with no address at all (WebRTC) falls back to a screen recording, which is a re-encode of what the player shows.
- The recording keeps going after you leave the page or close the tab: it moves to a hidden extension page (the `offscreen` permission). The popup lists running recordings with **Stop & save** and **Discard**, and the toolbar icon badge shows how many are running. On a few CDNs that only answer the player's own site, the recording stays in the page instead.
- Several recordings can run at once; each shows its own clock and resolution (`Recording live · 12:34 · 1080p`). Shortcut-clicking the same video again stops it.
- A stream that drops is waited out for up to an hour (`Reconnecting for 3:20 · 12:03 recorded`) and appended where it left off; after an hour down it is saved as it is. A stream that comes back at a new address, for example after a private or paid show, is followed.
- When picture and sound come as separate tracks, both are recorded. If only one could be recorded, the file name ends in `-audio` or `-video`.
- **Auto-record.** A page added under Auto-record in the popup is checked every 30 seconds while Chrome runs (`alarms`) and recorded as soon as its broadcast goes live, reaching back a few minutes. "With this tab" keeps a tab open for sites that only reveal the stream to their own player, reloading it every two minutes until live. HLS and DASH only.
- **Written to disk as it arrives.** Segments go into a file in the extension's origin private file system and are copied into Downloads at the end, so length is bounded by free disk space, not memory. A failed copy (disk full, folder not writable) is retried twice, then kept with a "Save again" / "Delete" row at the top of the popup's recent list; a recording cut short by Chrome quitting is saved at the next start. The copy needs free space equal to the recording's size.

## Limits

- Encrypted streams (DRM, AES-128) are not saved.
- A streaming video that has never been played has no manifest to retrace; play it briefly first.
- Some CDNs reject downloads without their Referer (HTTP 403); a CORS-tainted canvas cannot be read.
- Extensions cannot run on `chrome://` pages or the Chrome Web Store. `file://` pages need "Allow access to file URLs".

## Permissions and privacy

`activeTab`, `alarms` (auto-record checks, only while a page is set to auto-record), `downloads`, `offscreen`, `storage`, `webRequest` (observes `.m3u8`, `.mpd` and `.flv` addresses only; never blocks or changes a request), `declarativeNetRequestWithHostAccess` (only while a live recording runs outside the page: gives the extension's own requests to that stream's server the Origin/Referer the page's player already sends; tab requests untouched), plus access to all sites for the click handler. Requests go only to the media you chose, its CDN, a linked post, or the page a live recording started on. Your shortcut and recent downloads stay in Chrome on your machine.

## 한국어 요약

tugpic 은 단축키(기본 Alt, 맥은 Option)를 누른 채 좌클릭하면 커서 아래의 이미지·영상을 바로 저장하는 무료 오픈소스 Chrome 확장입니다. HLS·DASH 스트림과 blob: 영상, 글의 본문 이미지 일괄 다운로드, 목록에서 링크된 글 속 영상 다운로드를 지원합니다. 라이브 영상을 클릭하면 녹화가 시작되며, 페이지를 떠나거나 탭을 닫아도 계속 녹화하고, 여러 개를 동시에 녹화할 수 있고, 끊기거나 주소가 바뀐 스트림도 기다렸다가 따라갑니다. 서버·계정·분석 도구가 없습니다.
