Facebook Video Converter: Convert Facebook Videos to MP4 or Convert Videos for Facebook

I know that some of you would say Facebook video upload, download, and conversion can be finished by online services. Indeed, there are many sites like keepvid that can save or convert videos from a URL. But they usually depend on remote servers, may have file size or format limits, and often come with pop-ups, misleading buttons, or privacy concerns. Some tools also fail when the Facebook link is private, expired, or not directly accessible.

While WonderFox HD Video Converter Factory Pro is a versatile desktop tool that combines video downloading, conversion, compression, and basic editing in one workflow. You can use it to copy accessible Facebook videos for personal use, convert Facebook to MP4 or MP3, and deal with Facebook video upload issue by making the file smaller and more compatible.

Copying a Facebook video can mean two different things: copying the video link for sharing, or saving the video file to your computer. If you only want to share a post with friends, use Facebook’s Share or Copy link option. If you need a local file for backup, offline playback, editing, or reposting to your own page, use a downloader/converter and make sure you have the right to save or reuse the content.

Public and accessible videos are generally easier to process. Private videos, live replays, group videos, or videos with account restrictions may fail in many downloaders. In that case, check the link permission first, or ask the owner for the original file instead of trying unsafe third-party sites.

If you only need a free tool to copy accessible Facebook videos and do simple conversions, WonderFox Free HD Video Converter Factory is another option. Open Downloader, click New Download, paste and analyze the Facebook video URL, choose a resolution, click OK, set an output folder, and hit Download All. After that, you can convert the saved video to MP4, MP3, MKV, AVI and other common formats.

Online Facebook video savers can also work for some public links. However, they may be unstable, slow, ad-heavy, or limited by file size and network speed. For safer long-term use, a desktop downloader/converter is usually easier to manage.

Q1. What is the best format for uploading videos to Facebook?

MP4 and MOV are the most recommended choices. In daily use, MP4 with H.264 video and AAC audio is usually the safest option because it balances compatibility, quality, and file size.

Q2. Can I copy any video from Facebook?

No. You should only copy videos you own, videos in the public domain, or videos you have permission to save. Private, restricted, copyrighted, or removed videos may not be available and should not be downloaded without authorization.

Q3. Why does my Facebook video fail to upload?

Common reasons include unsupported codecs, an oversized file, unstable network, too long duration for the selected placement, unusual resolution/aspect ratio, or a temporary Facebook processing issue. Converting to MP4, compressing the file, and trimming the video can often help.

Q4. Can I convert Facebook video to MP3?

Yes. After saving an accessible Facebook video, import it to Converter, choose MP3 as the output format, and click Run. Make sure the audio is used legally and with permission.
