Android is not a single browser or a single file manager. Samsung phones, Pixel devices, tablets and many other Android devices can run different browsers with different download interfaces. FAST-VID can work in a modern mobile browser, but the save prompt and the exact folder name are controlled by that browser and by Android.
The core workflow is the same as on a computer: paste a supported public link, request metadata, choose an available format and save the finished file. The difference is that the screen is smaller, mobile data may be limited, and the browser may ask where the file should go.
Before you start
- Use a current Android browser such as Chrome, Firefox or Samsung Internet.
- Make sure you own the content or have permission to download it.
- Check free storage and whether you are on Wi-Fi or mobile data.
- Keep the source link public. FAST-VID does not log in to platforms or use platform cookies.
FAST-VID does not install an Android app. It is a browser page with JavaScript, a session cookie and server-side processing. The browser needs JavaScript enabled and permission to save downloads.
The mobile browser workflow
1. Copy the public link
Open the source app or browser and use the share or copy-link action. Paste the direct post or video link into FAST-VID. A profile page or a private message is not a usable media link. If the page only works while you are signed in, FAST-VID will not see your authenticated view.
2. Paste and request media info
Open the FAST-VID downloader, paste the URL into the Media URL field and tap Get media info. On a narrow screen, the input and button stack vertically. The result card appears after the lookup and shows the title, available video qualities and any available audio choices.
3. Choose a format
The video tab offers available MP4 qualities. The audio tab may offer MP3 and M4A. Tap a format card to select it, then use the download button. If the result is MP4, a preview button may appear; preview uses the browser's native video player. MP3 and M4A are download-only.
4. Save the file
When the job finishes, FAST-VID asks the browser to save the file. Depending on the browser, you may see a download notification, a “Download complete” item, or a prompt asking where to save. If the first attempt does not start, use Save file instead in the result card.
Where Android saves downloads
Chrome commonly saves downloads to the device's Downloads collection, visible through the browser's Downloads page and the Android Files app. Samsung Internet, Firefox and other browsers may use their own download list or a different folder. The exact path can also depend on whether the browser uses shared storage or an app-specific download directory.
Open your browser's Downloads screen first. If the file is not there, open the Files app and look under Downloads. Some file managers label the same location “Internal storage → Download” or show it under a browser-specific folder. Use the file's name or the approximate time of download to locate it.
Android may show a notification when a download completes. Tapping the notification can open the file or offer a choice of apps. If the notification disappears, the browser's download history and Files app are the next places to check.
Opening downloaded media
An MP4 file usually opens in the default gallery or video player. Playback depends on the codecs inside the file. H.264 video with AAC audio is widely supported on Android; AV1 or HEVC may work on newer devices but can fail on older ones. If the default player rejects a valid file, try another media player that supports the codec. The MP4 format guide explains the container and codec distinction.
MP3 and M4A are audio files. The default music player may find them in the Downloads folder, but some players only scan specific library folders. Open the file directly from Files if it does not appear in the music app.
Do not rename an MP4 to MP3 or otherwise change the extension to force playback. Renaming does not convert the media and can make the file harder to open.
Storage permissions and browser prompts
Modern Android browsers often save downloads through the system download collection without asking for broad storage access. Other browsers or older Android versions may request permission. Grant only the permission the browser actually needs for the action you requested, and do not disable system security settings to make a download work.
If a browser asks where to save, choose a location you can access later. If it asks for permission and you decline, the download may fail silently or be saved to an app-specific area. Check the browser's download list and Android app settings before assuming FAST-VID failed.
FAST-VID cannot grant Android permissions, choose a browser's storage provider or move a file after the browser saves it.
Troubleshooting Android downloads
The download button does not respond
Make sure the result is complete and a format is selected. If the page is still busy, wait for the status to finish. If the automatic save is blocked, use Save file instead. Try a current browser if the page is visibly broken.
The file is not in Downloads
Check the browser's own downloads list. It may have saved to a private app folder or a different location. Use the Files app search and sort by newest.
Android asks for storage permission
Review the prompt and grant only what is required. If you decline, the browser may not be able to save to the location you chose. Do not grant broad permissions to unrelated apps.
The video will not play
The codec may not be supported by the default player, or the file may still be incomplete. Check the file size in the browser's download list and try another player. Avoid re-downloading repeatedly over mobile data until you know the file is incomplete.
The file is too large
Choose a lower video quality or an audio-only output. FAST-VID's default 500 MB limit applies to the final file. Mobile data plans may also make a large download expensive.
Mobile data and storage
Video downloads can use a lot of mobile data. Use Wi-Fi when possible, especially for high-resolution files. Check remaining storage before a large job; Android may stop a download when free space runs out. Audio files are usually smaller, but a long recording can still be significant.
FAST-VID keeps completed files temporarily on the server. The browser then saves a copy to your device. The server copy expires as part of normal cleanup; the local copy remains until you delete it.
Responsible use
Only download content you own or are authorized to download. Do not use FAST-VID to save private, restricted or login-gated material, and do not republish someone else's video without permission. Follow the source platform's terms and applicable copyright law. FAST-VID is independent and is not affiliated with Android, Google or any media platform.
Frequently asked questions
Do I need to install an Android app?
No. FAST-VID is a website used in a mobile browser. There is no FAST-VID Android app to install.
Where is the downloaded file on Android?
Usually in the browser's Downloads list and the Android Downloads folder. Other browsers may use a different folder, so check the browser's own download screen first.
Can I download over mobile data?
Yes, if your browser and connection allow it, but large videos can use significant data. Wi-Fi is usually the better choice for high-resolution files.
Why will the video not open?
The player may not support the codec inside the file, or the download may be incomplete. Try another player or a different available quality. MP4 with H.264/AAC is generally the safest combination.
Can FAST-VID access private TikTok or Instagram videos?
No. FAST-VID does not log in or import platform cookies. Private, follower-only and login-gated posts are outside the supported workflow. Public TikTok links are covered in the TikTok workflow guide.
