Universal Downloader — Download Videos, Thumbnails, Screenshots & Files
Paste a link to auto-fetch video thumbnails & info from YouTube, TikTok, Vimeo, Dailymotion and Reddit — or drop your own video file to grab screenshots, frame sheets and details. No upload, no sign-up, free forever.
Quick answer: Free universal downloader: paste a link from YouTube, TikTok, Vimeo, Dailymotion or Reddit to auto-fetch thumbnails & metadata, or drop any video file for screenshots & frame sheets. 100% in your browser.
Supported: YouTube · TikTok · Vimeo · Dailymotion · Reddit | detected-only: Instagram · Facebook · X
Browser code alone cannot rip platform videos (technical + terms-of-service walls — that is why every "instant MP4" site routes your link through their server). cobalt is the free, open-source engine behind the good ones — run it on a free host in ~10 minutes, paste its URL here once (saved only in your own browser, never on our side), and real MP4/MP3 downloads work right on this page.
🆓 Free cobalt server — step by step (no credit card)
Option A — Koyeb (easiest, free tier, no card):
- Sign up at koyeb.com (free account, no card).
- Create App → choose Docker → image:
ghcr.io/imputnet/cobalt:latest - Set port 8000, and environment variables:
API_URL=https://your-app-name.koyeb.app/
API_PORT=8000
CORS_WILDCARD=1 - Deploy → copy your
.koyeb.appURL → paste it above → 💾 Save → done.
Option B — Hugging Face Space (free CPU, generous RAM): create a new Space → Docker → Blank, add a Dockerfile containing:
FROM ghcr.io/imputnet/cobalt:latest ENV API_PORT=7860
Set app_port: 7860 in the README header and add the variable API_URL=https://your-username-your-space.hf.space/ in Settings → Variables. Your Space URL is the server address.
Option C — any VPS with Docker:
docker run -d --restart=always -e API_URL=https://your-domain.example/ -e CORS_WILDCARD=1 -p 9000:9000 ghcr.io/imputnet/cobalt:latest
Only download public content you have the right to save — your own videos, Creative-Commons material, or content the platform allows. Cobalt is free & open-source (imputnet/cobalt); your links go straight from your browser to YOUR server — nothing touches ours.
💡 Direct video-FILE downloads violate platform terms — this tool gives you what is honestly possible in your browser: thumbnails, metadata and file tools.
How to use
- Paste a link — copy any video URL (YouTube, TikTok, Vimeo, Dailymotion, Reddit) into the box. The platform is auto-detected and the title, author and thumbnail are fetched instantly — fetching starts automatically on paste.
- Download what you need — grab the thumbnail in every available size (YouTube includes max-res), or open the original post.
- Or drop your own file — drag any video (MP4/WebM/MOV) onto the drop zone to see duration, resolution and size, capture PNG screenshots at any moment, or build a 6-frame contact sheet in one click.
About this tool
One page for every download task. From a link: paste any video URL and the tool detects the platform, then auto-fetches the title, author and best thumbnail via official public APIs — YouTube, TikTok, Vimeo, Dailymotion and Reddit are fully supported, and YouTube thumbnails download in every size including max-resolution (maxresdefault). From your device: drag & drop any video file (MP4, WebM, MOV) to instantly see its duration, resolution and file size, capture a crisp PNG screenshot at any moment, or generate a 6-frame contact sheet for previews and storyboards. Everything runs 100% inside your browser — files are never uploaded to any server. Honest note: direct video-FILE ripping from platforms needs server-side tools (and breaks most platforms' Terms of Service); this downloader gives you everything that is genuinely possible in a browser: metadata, thumbnails, screenshots and file analysis. Want the actual video files? Connect your own free cobalt server (open-source engine, 10-minute setup on Koyeb or Hugging Face — no card) in the box below and the MP4/MP3 buttons save real files through YOUR server — your links never touch ours or any third party's.
