How to use AceThinker Free Online Video Downloader on your device
Step one – Visit AceThinker Free Online Video Downloader website.
To use this tool, you will have to visit the official site of AceThinker Free Online Video Downloader. On the homepage, you will see a URL bar as well as a download button.
Step two – Begin to download your videos.
AceThinker lists YouTube among its supported sites, but YouTube’s Terms of Service do not allow downloading content except where the service expressly authorizes it (such as offline downloads in the YouTube app with YouTube Premium) or with prior written permission from YouTube and the rights holders. All you need to do is to copy the link of the video you want to download from YouTube and paste it on the URL bar of AceThinker Free Online Video Downloader.
Click on the download button to initiate download after pasting the link. Select the video quality and format you want. Now, right-click on “Download” and click on “Save link as…” and choose the folder you want to save your video.
Step three – Download videos from another website.
The same steps work for other sites on AceThinker’s supported-sites list, such as Vimeo, Dailymotion, Instagram or TikTok; Crunchyroll is not on that list as of October 2026. The step is the same as downloading videos from YouTube. Copy the link of the video you want to download from the supported site and click the download button to analyze the video.
Select the format and quality you want. You can also save in audio format (MP3) if you are downloading a music video. Click “save link as…” when you right-click on the download icon.
Step four – Play the video you downloaded.
After your download is complete, go to the folder you saved the video. You can double-click on the video to open it immediately, or you can open the video using your favorite video player when you right-click on it.
Step five – Transfer downloaded clip to your preferred device.
You can transfer the video you downloaded from the folder to your mobile device. All you need to do is connect your phone to your PC using a USB cable, then drag the video and drop it in any folder you want on your mobile device storage. After the transfer is complete, you can directly play the video from your mobile device since it supports MP4 format.
Note: The free online tool tops out at 720p, so it cannot download 1080p, 4K or 8K video. There is also a limit to how you download free videos. If you want Full HD or Ultra HD files, you need the paid desktop app, now sold as Aqua Clip (formerly AceThinker Video Keeper). You will know more about the Pro Version as you read.

Is It Legal to Download Online Videos?
Downloading is governed by copyright law and each website’s terms, not by the downloader you use. AceThinker itself tells users to follow copyright laws and the terms of service of the websites they download from.
YouTube’s Terms of Service say users may not access, reproduce or download any part of the service or its content except as expressly authorized by the service, or with prior written permission from YouTube and, where applicable, the rights holders. YouTube’s own authorized route is offline downloads in the YouTube app, a YouTube Premium benefit that also covers playlists.
Safer uses include your own uploads and videos the creator explicitly offers for download. For other options, see this walkthrough of the iTubeGo YouTube downloader or this overview of a free online video downloader for other websites.
