How to convert video format online
Converting a video format with Yuelu Tools is straightforward:
1. Select or drag your video file into the upload area. The converter accepts MP4, MOV, AVI, MKV, WebM, FLV, and most common video formats.
2. Choose your output format. Select MP4 for maximum compatibility across all devices and platforms, WebM for modern web delivery with smaller file sizes, or MOV when working in video editing workflows that prefer QuickTime containers.
3. Optionally open Advanced settings to customize video codec, audio codec, or sample rate. You can also remove the audio or video track if you only need one media type.
4. Click "Convert Video" and wait for processing. The conversion runs entirely in your browser without uploading your file to any server. When complete, preview and download the converted video.
Flexible video format conversion
Choose MP4 for broad compatibility, WebM for modern web delivery, or MOV for workflows that prefer a QuickTime container. Advanced controls let you choose a compatible video codec, audio codec, or audio sample rate.
The converter keeps the original dimensions and adjusts odd pixel dimensions only when an encoder requires an even frame size.
Private, browser-based processing
Conversion happens directly on your device. The selected video is never sent to a remote conversion server, so you stay in control from selection to download.
The first conversion may take a moment while your browser prepares the converter. Your video is not uploaded during this setup, and later conversions can start faster.
Compatible format and codec choices
MP4 and MOV use H.264 video with AAC audio. WebM uses VP8 video with Vorbis audio. You can also remove the video or audio track when the selected container supports the remaining track.
Frequently asked questions
Are my videos uploaded?
No. The source video and converted result stay in your browser. The first use only prepares the converter your browser needs.
Which output format should I choose?
Choose MP4 for the widest compatibility, WebM for web delivery, or MOV when a QuickTime container fits your editing workflow.
Can I change the video and audio codecs?
Yes. Open Advanced settings to choose a codec combination supported by the selected container or to remove one media track.
What is the difference between video compression and conversion?
Compression reduces file size by lowering quality or resolution. Conversion changes the container format or codec without necessarily reducing size. Use the video compressor when file size is your primary concern, and the converter when you need a specific format or codec.
Can I convert MOV to MP4?
Yes. Select your MOV file, choose MP4 as the output format, and click Convert Video. The converter will re-encode to H.264/AAC MP4 for maximum compatibility with all devices and platforms.
Can I convert MP4 to WebM?
Yes. Select your MP4 file, choose WebM as the output format, and the converter will encode to VP8 video with Vorbis audio. WebM typically produces smaller files than MP4 and is ideal for modern web browsers.
How long does video conversion take?
Conversion time depends on video duration, resolution, output format, and your device speed. A 2-minute 1080p video typically converts in 1-3 minutes on a modern laptop. The first conversion may take longer while your browser loads the conversion engine.
Does video conversion reduce quality?
Re-encoding to a different codec can introduce some quality loss, but it is typically minimal with H.264 and VP8 encoders. If your source is already in the target codec (e.g., converting H.264 MP4 to H.264 MOV), quality loss is negligible as only the container changes.
Can I remove audio from video?
Yes. Open Advanced settings and choose "None" for the audio codec, or use the dedicated Remove Audio from Video tool for a simpler workflow focused on extracting silent video.
