Any file up to 500 MB. Drop several files and they come back as one ZIP. Many image, audio and video conversions run in your browser; anything else is uploaded and removed within the hour.
Convert your WEBM files to MOV format quickly and easily. This tool is perfect for users who need to make web-optimized video content compatible with Apple ecosystem software.
WEBM is an open-source container primarily designed for web streaming using VP8 or VP9 codecs. MOV, developed by Apple, is a proprietary container often associated with QuickTime and professional editing workflows. During the conversion process, we repackage the video and audio streams. Since both formats are containers, the conversion primarily focuses on changing the underlying structure to ensure compatibility with macOS or iOS native players, while the actual video data undergoes transcoding.
Because both WEBM and MOV typically utilize lossy compression, the conversion process involves re-encoding the video, which can lead to a slight loss in generational quality.
We built this project so anyone can convert files without paywalls, accounts, or hidden limits. Here is what that promise means in practice.
Every converter on ConvertX is free to use: no trials, no premium tiers, and no credit packs. We will never put core conversion features behind a subscription. Whether you convert one photo or a hundred files a week, the price stays zero.
Many image, audio, and video conversions run entirely in your browser. Your files never leave your device for those jobs. When server processing is required for documents or specialized formats, uploads are handled securely and removed automatically — typically within one hour.
A quick guide to strengths and trade-offs of popular formats — so you pick the right one before converting.
