Choose the right format

MP4 for sharing videos

WebM for websites
Use WebM for video embedded on a web page. Check that your website platform accepts it.
MP3 for listening and sharing
MP3 keeps music and recordings small. Keep the original if you plan to edit it later.
WAV or FLAC for lossless audio
Choose WAV for editing, or FLAC for a smaller music library without lossy compression. Neither can restore detail missing from the original recording.

Video & Audio Converter FAQ

Is the FastConvert video and audio converter free and watermark-free?

Yes. You can convert without an account or watermark. The Free plan includes 20 conversions per 24 hours. Paid plans allow larger files and batches.

Which video and audio formats can I convert?

Supported video formats include MP4, MKV, AVI, MOV, WebM, WMV, FLV, MPEG, M4V, TS, 3GP, and more. Supported audio formats include MP3, WAV, AAC, OGG, FLAC, Opus, M4A, WMA, and AIFF. Browse the available video and audio conversions.

How do I convert a video or audio file online?

Add files from your device, direct public HTTPS file links, Google Drive, or Dropbox. Choose an output format and quality preset, then click Convert. Download the files when they are ready.

Can I convert H.266 / VVC videos?

Yes. FastConvert can convert H.266 / VVC video in supported containers such as MP4 and MKV. To encode a video as VVC, choose MP4 or MKV, select Custom, then choose H.266 / VVC under Video codec. Encoding is slow and player support is limited, so check your destination player's compatibility before converting a batch.

Can I convert MP4 to MP3 or extract audio from a video?

Yes. Upload a video with sound and choose an audio format such as MP3 or WAV. You can also set start and end times to extract just one section.

What happens if a video has no audio track?

You can still convert it to another video format. Audio extraction reports an error because there is no sound to extract.

Can I mix video and audio files in the same batch?

Yes. Add both types of file and choose an output for each one. For example, convert a MOV clip to MP4 and a WAV recording to MP3 together.

Will video or audio conversion reduce quality or file size?

It depends on your settings. Smaller file trades some detail for size. High quality keeps more detail but can produce larger files. Converting to WAV or FLAC avoids lossy audio compression, but cannot restore detail missing from the source.

What do the video conversion profiles change?

Start with Recommended for everyday use. Choose High quality for more detail, Smaller file to reduce size, or Fast conversion to shorten processing. The Smaller file preset limits video to 1080p and 30 fps. Choose Custom to adjust the settings yourself.

What do the audio conversion profiles change?

Recommended balances sound quality and size. High quality keeps more detail in lossy formats. Smaller file saves space, and Speech / Podcast is for voice recordings. Choose Custom to set quality, sample rate and channels yourself.

What is the maximum video or audio file size?

Each video or audio file can be up to 100 MB on Free, 300 MB on Basic, or 1 GB on Pro.

Can I batch convert multiple video or audio files at once?

Yes. Convert up to 2 files per batch on Free, 4 on Basic, or 12 on Pro. Set options for each file, or sign in to apply shared settings with a recipe.

How long does video or audio conversion take?

It depends on the recording's length, format and settings. Video usually takes longer than audio. Each file has a processing limit of 2 minutes on Free, 15 minutes on Basic, or 30 minutes on Pro. This limits conversion time, not the length of your recording.

Can I convert a video or audio file from a URL?

Yes. Choose URL in the upload area and paste one or more direct public HTTPS links to supported video or audio files. URL import is available on every plan, without an account. Your plan’s batch, file size, and conversion limits still apply. Video platform pages, streaming playlists, and links that require sign-in are not supported; use the Google Drive or Dropbox picker for files from those services.

Can I convert video or audio files from Google Drive or Dropbox?

Yes. Choose Google Drive or Dropbox in the upload area and select your files. You can download the results or, on a paid plan, send them to a cloud folder.

Does FastConvert work on phones, tablets, Mac, Windows, and Linux?

Yes. Use a modern browser on your phone, tablet or computer. There is no app to install.

Are my uploaded video and audio files private, and when are they deleted?

Yes. FastConvert temporarily uploads and stores original and converted files for processing and download. Files are kept for 24 hours on Free, 1 week on Basic, or 1 week on Pro, then scheduled for automatic deletion. We do not use uploaded files to train AI models. If you choose a Google Drive or Dropbox import or export, the selected provider receives or supplies the file as part of that request.
