How to use the video converter
Add one source file
Select a file on your device or use the URL option for a direct HTTPS link to the media. A shared watch page can display a video without exposing a readable media file. If import fails, choose a downloaded copy instead.
Select the output
Choose MP4 to keep picture and sound in an H.264 viewing copy. Choose MP3 for a listening copy. Video outputs offer a resolution menu. The quality control appears only when the encoder uses that setting.
Download each format
Start conversion and save the result. To make a second output, choose Convert this file to another format. The video converter keeps the original input selected, so you can change the settings without downloading and reimporting the first result.
Which video converter output should I choose?
Video with sound
Choose MP4 for an H.264 viewing copy, or match the container and codecs requested by the receiving player below.
Audio only
Choose MP3 for a listening copy, WAV for decoded PCM audio or another supported audio format. The input must contain a readable soundtrack.
MP4, MOV and M4V
These outputs target H.264 picture with AAC sound when audio is present. MP4 is the default. MOV writes a QuickTime container. M4V writes an MP4 container with the .m4v extension. Select the one the receiving application asks for. An instruction that specifically requires ProRes video or PCM audio describes different stream requirements from choosing MOV here.
MKV and WebM
MKV writes a Matroska file with H.264 picture and AAC audio. WebM on this page writes VP8 picture with Opus audio. Check the codec as well as the extension when a website specifies an upload profile. A platform requesting VP9 inside WebM requires a different video stream. Neither option provides a selector for preserving an arbitrary collection of language tracks or subtitle streams.
MPG and OGV
Select MPG for MPEG-2 video with MP2 sound at 25 frames per second. Select OGV for Theora video with Vorbis sound. These encoders use their own settings, so there is no quality slider for either choice. OGG in the same menu is an audio output. If you want to keep the picture with Vorbis audio, choose OGV.
Audio-only outputs
For MP3, the video converter uses variable-quality encoding. AAC and M4A both encode AAC sound at 160 kbps, with M4A packaging the track in an MPEG-4 container. WAV writes 16-bit PCM. FLAC uses lossless compression, and OGG encodes Vorbis audio. All six choices discard the video frames and require readable audio in the source. Use the dedicated MP3 page if you need to choose a specific MP3 bitrate.
How video converter settings affect detail and file size
Resolution and frame dimensions
Resolution sets a ceiling on output height. With square pixels and a 720p ceiling, a landscape 1920 × 1080 frame becomes 1280 × 720. A portrait source with the same total number of pixels is reduced according to its height, producing a much narrower frame at 720 lines. Width follows the proportions of the source. Choose Original when screen text or small details need to retain their original dimensions.
Quality for H.264 and WebM exports
For MP4, MOV, MKV, M4V and WebM, the quality control adjusts video encoding. It initially reads 65 and can be moved from 10 to 95. The percentage is a quality setting, not a predicted reduction in bytes. Two files with the same duration and dimensions can compress differently when one contains a mostly static picture and the other contains motion throughout.
Checking an upload limit
The result panel shows original and new file size. If a file must fit a fixed upload limit, use that actual size rather than estimating from resolution alone. The video converter offers control over format and encoding. For a target expressed in megabytes, use the compressor. Check the resulting format as well as the size if the destination accepts only certain containers.
How to check one export and save another format
Check a video output
Open the download in the destination application and seek past the opening frame. If it plays locally but a published copy fails, verify which file the application loads and whether its decoder accepts the exported streams.
Check an audio output
Select a section where the original has audible sound and compare the same instant in the download. A recording that displays captions without an audio track cannot produce speech from the caption words.
Make another copy from the same source
Saving the first result matters before you return to settings for a second format. The new conversion starts with the original input, and the earlier result panel is cleared. Keep the tab open until the download has been saved. For several source files that share a single output format, the batch tool gives each source a separate row and download.
Video converter troubleshooting
Why does my converted video take up more space?
A phone may record in HEVC, which can store a detailed picture in fewer bytes than a new H.264 export. If duration and dimensions match, lower Quality for a smaller copy. Start each attempt from the original to avoid accumulating compression errors.
Why do I get “This file has no audio track to extract”?
The source contains no detectable audio track to extract. Check the track list in the original player. Check for a separate microphone recording or an audio file saved alongside the video. A different output format cannot recover a microphone that was switched off.
Will I keep subtitles and alternate audio languages?
Text burned into the picture stays visible. Selectable captions and extra audio tracks are separate streams. This page has no controls to map every stream to the output. If you need two languages, commentary or a subtitle file, keep the original and verify those tracks individually before handing over a converted copy.
What should I do if the preview is blank?
Try opening the original file in its usual player and seek near the end to check for a truncated file. The preview and the video converter use different decoders. If conversion finishes, open the download in your target player.
Why does the video converter reject my link?
The video converter needs a direct HTTPS file link and permission from the host to read it. A watch page or shared album usually returns HTML. Download the clip from that service first, then choose the file from your device.
Can I convert several videos with the same settings?
Open the batch video converter to apply one format to several recordings. Each source gets its own download. To make multiple formats from a single input, use the “Convert this file to another format” action here.
