Compress Video for Telegram
Make it small enough to send fast — and good enough that Telegram's compressor never gets a say.
Runs entirely in your browser. Your videos never leave this device.
Telegram takes files up to 2 GB free (4 GB with Premium), but any video you send the normal way gets run through Telegram's own compressor, and multi-gigabyte files are slow for you to upload and for everyone else to download. Compressing first fixes both: pick an exact MB target or a quality preset, get a clean MP4, and send it as a file so Telegram leaves it alone. Everything runs locally in your browser — the video never leaves your device.
Does Telegram compress videos?
Yes — any video sent as media (the normal way) is re-encoded by Telegram, usually at a visibly lower quality. Videos attached as a file are delivered exactly as-is, up to 2 GB on a free account or 4 GB with Premium. The best of both: compress the video yourself to a size you're happy with, then send that as a file.
The facts that matter
| Max file size (free) | 2 GB |
|---|---|
| Max file size (Premium) | 4 GB |
| Videos sent as media | Re-encoded by Telegram's compressor |
| Videos sent as a file | Delivered untouched, original quality |
| Safest format | MP4 (H.264 + AAC) — plays inline on every Telegram app |
Get a better result
- Send the compressed MP4 as a file (paperclip → File), not as a video — Telegram won't re-encode it.
- Sending to someone on mobile data? Target 50–100 MB in exact-size mode — quick to download and still very watchable on a phone.
- For casual group-chat clips, the Small preset is usually plenty; save High for footage people will watch full-screen.
- The first compression downloads a ~32 MB encoding engine once; it's cached after that, so later runs start immediately.
- Queue several clips at once — they compress one after another while you do something else.
Frequently asked questions
How do I send a video on Telegram without losing quality?
Attach it as a file instead of a video: tap the paperclip, choose File, and pick your video. Telegram delivers files byte-for-byte with no re-encoding. If the original is huge, compress it here first — you choose the quality trade-off instead of Telegram's compressor choosing for you.
What's the biggest video I can send on Telegram?
2 GB per file on a free account, and 4 GB per file with Telegram Premium. The limit is per file, so a longer video only fits if it stays under that cap or gets split into parts.
Telegram already allows 2 GB — why compress at all?
Speed and courtesy. A 1.5 GB video ties up your connection for a long time, and everyone who opens it downloads the same 1.5 GB, often on mobile data. Compressed to a few hundred MB or less, it sends in a fraction of the time and still looks good on a phone screen.
Does this tool upload my video to a server?
No. The encoder (ffmpeg.wasm) runs inside your browser, so the video is processed on your own device and never uploaded anywhere. That also means there's no queue and no waiting behind other users.
Can I compress to an exact size?
Yes — switch to target-size mode and type the MB you want. The encoder reads the video's duration, computes the bitrate needed to land on that size, and automatically retries at a lower bitrate if the first pass comes out over.
Are there limits, watermarks, or signups?
No watermark, no account, no daily limits, and no artificial file-size cap. Two honest caveats: encoding runs at browser speed, so long videos take a while, and files over about 1 GB can strain the browser's memory.
