How do I convert a video to a different format?

Drop your video into a browser-based converter, select the output format (MP4, MOV, WebM, AVI), and click convert. The tool re-encodes the video in the new container format. Takes 10-60 seconds depending on file size. No software download needed — runs in your browser.

Which video format should I use?

MP4 for everything — it is universally compatible across all devices, browsers, social media platforms, and video players. MOV only if required by Apple-specific workflows (Final Cut Pro). WebM for web-only embedding (smaller files). AVI for legacy systems. When in doubt, convert to MP4.

Does converting video formats lose quality?

Re-encoding always involves some quality loss because the video is decoded and re-encoded. However, at high quality settings, the loss is imperceptible. For zero-loss, some tools offer remuxing (changing the container without re-encoding the video stream), but this only works for compatible codec/container combinations.

How do I convert MOV to MP4?

MOV and MP4 are both containers that typically hold the same H.264 video codec. Drop your MOV file into the converter, select MP4 output. The conversion is fast because the underlying video codec is often the same — only the container changes. The resulting MP4 plays everywhere.

Can I convert video on my phone?

Yes. Open the converter in your mobile browser. Upload from your camera roll or files app. The conversion runs on your phone processor. Download the converted file. Works on iPhone (Safari) and Android (Chrome). No app needed.

Why is my converted video file larger than the original?

This happens when converting from a highly compressed format to a less compressed one (e.g., WebM to AVI), or when the converter uses higher quality settings than the original. To keep file sizes small, convert to MP4 or WebM and use the video compressor after conversion if needed.
