Why is my Telegram video stuck at 0% when downloading?

Most often it is a stalled connection to the Telegram data center: pause and resume the download, toggle your network, or restart the app. On Telegram Web, a stale service worker or full browser cache can also stall downloads — clear site data for web.telegram.org and reload.

Why is there no download option on a Telegram video?

Some media types and some chats simply do not expose a save option in every Telegram client. If you can watch the video in your logged-in Telegram Web session, a browser extension like TG Downloader can add a save button for it. No tool can download content your account cannot already view.

Why do large Telegram videos fail halfway through downloading?

Long downloads are sensitive to connection drops, sleep mode, and low disk space. Keep the computer awake, confirm free disk space of at least twice the file size, and prefer a wired or stable connection for multi-gigabyte files.

Telegram video not downloading? 8 fixes that actually work

Last updated: 11 July 2026 · By the TG Downloader team. We build download tooling on top of Telegram Web, which means we debug stuck Telegram downloads for a living. These are the fixes we actually use, in the order we actually try them.

Stuck at 0%. Spinning forever. Failing at 99%. No download button at all. Telegram download problems come in a few distinct flavors, and each has a different fix. Work through these in order — they're sorted from fastest to most drastic.

1. Pause and resume the download

Telegram serves video in small chunks rather than as one file, and a download stalls when the connection drops mid-chunk — which is why it freezes at an oddly specific percentage and sits there. Click the progress circle to pause, wait two seconds, click again to resume: that forces a fresh request for the chunk that died. This fixes more stuck downloads than anything else on this list.

2. Try the other Telegram Web

Little-known fact: web.telegram.org/a and web.telegram.org/k are two entirely separate web apps — different codebases, different bugs. We maintain compatibility with both, and in our experience a download that misbehaves in one frequently works first try in the other. Swap the letter in the URL, log in, retry. Thirty seconds, and it rescues a surprising share of “broken” downloads.

3. Check your storage — both kinds

A download will silently crawl or fail if your disk is nearly full. Check free space on the drive that holds your Downloads folder, and aim for at least twice the video's size. On mobile, also check Telegram's own storage limit (Settings → Data and Storage → Storage Usage).

4. Restart Telegram (properly)

On desktop, quit from the system tray icon — closing the window only hides it. On Telegram Web, do a hard reload: Ctrl+Shift+R (Cmd+Shift+R on Mac).

5. Clear the cache

Desktop app: Settings → Advanced → Manage local storage → Clear. Cached media can corrupt and block re-downloads of the same file.
Telegram Web: clear site data for web.telegram.org (padlock icon → Site settings → Delete data), then log in again. This resets a stale service worker — a common cause of Web downloads that never start.

6. Toggle your network (and VPN)

Switch Wi-Fi off and on, or try another network. If you use a VPN, try toggling it — some networks throttle Telegram's data centers, and a VPN changes the route (or is itself the bottleneck).

7. Keep the machine awake for big files

Multi-gigabyte videos fail when the computer sleeps mid-download. Temporarily disable sleep, keep the lid open, and let it finish. If a large file has failed halfway repeatedly, delete the partial file, clear cache (fix 5), and restart the download once with sleep disabled.

8. No download button at all? Use a different route

Sometimes nothing is “broken” — the client just doesn't offer a save option for that media type in that chat. If you can watch the video in your own logged-in Telegram Web session, the TG Downloader extension adds a one-click Save button on it and downloads in original quality straight to your Downloads folder. Install it free (5 downloads/day, no signup) — it's often the 30-second fix when the built-in option refuses to appear.

To be clear about scope: the extension works with content your account can already view. It doesn't bypass permissions or fix server-side problems — if Telegram itself is down (check their status), nothing will download until it recovers.

Symptom → most likely cause, at a glance

Stuck at 0% → stalled first chunk: pause/resume (fix 1), then network toggle (fix 6).
Frozen at an odd percentage → a chunk died mid-stream: pause/resume, or restart the download.
Fails at 99% → almost always disk space or an overzealous antivirus quarantining the finishing file — check both.
“Downloading” forever with no progress → stale service worker on Telegram Web: hard reload, then clear site data (fix 5).
No download option anywhere → not a bug; that media type simply isn't offered a save in your client (fix 8), or try the other web app (fix 2).
Every download fails, every chat → your side: network, VPN, disk, or an extension conflict. Try a clean profile or another browser to isolate.

Why Telegram Web downloads behave differently from the desktop app

The desktop app talks to Telegram's data centers directly over its own protocol (MTProto) and manages its own cache. Telegram Web lives inside browser rules: media streams over HTTPS in chunks, a service worker sits between the page and the network, and the browser's download manager handles the final file. That middle layer — the service worker — is powerful but can go stale, which is why “clear site data and log back in” fixes Web problems that the desktop app never has. It's also why we built our extension to reassemble files from the same stream the player uses: it works with the browser's pipeline rather than fighting it.
