Complete guide — Download videos in 2026
What is DownloadAllInOne?
DownloadAllInOne is a free online tool that lets you download videos from YouTube, TikTok, Instagram and Facebook in seconds, without registration and without installing software. Just paste a link to get an MP4 file in high quality with audio included.
Why choose our tool?
Most online download tools suffer from the same problem: they give you the video without audio for high qualities, or redirect you through pages of ads before failing. Our approach is different:
- Audio always included: Our server automatically merges the video and audio track into a single MP4 file, even for 1080p and 4K resolutions that require a technical merge.
- TikTok without watermark: We download the original source without the @username watermark.
- 4 platforms in one tool: No need to juggle multiple sites.
- Actively maintained engine: Powered by yt-dlp, regularly updated by the open-source community.
Which quality should I choose?
For mobile viewing, 720p is more than enough and saves space. For a large screen, 1080p Full HD is the right balance. 4K Ultra HD is ideal for archiving or watching on a 4K display. For TikTok and Instagram, the platform usually offers the best available quality directly.
Is it legal?
Downloading videos for strictly personal use is generally tolerated in the vast majority of countries. The golden rule is simple: you can save content for yourself, but you cannot redistribute or monetise copyrighted content without the creator's explicit permission. Always respect creators' work.
