Ultimate Secure Video Tool: Convert, Compress, Extract

CitosConvert Video Tools revolutionizes the way you handle video files on the web. In an era where data privacy is paramount, we offer a solution that processes your videos 100% locally on your device. Unlike traditional online converters that require you to upload massive files to a remote server—wasting your data plan and risking your privacy—CitosConvert utilizes advanced WebAssembly (FFmpeg) technology to bring the conversion engine directly to your browser.

Convert MOV to MP4 for Windows & Web

iPhone users often face compatibility issues with MOV files when transferring them to Windows PC or Android. Our tool provides a seamless MOV to MP4 converter. MP4 is the most universally accepted video format, ensuring your videos play perfectly on TVs, consoles, and websites.

Extract Audio: Video to MP3 Converter

Have a music video, a podcast recording, or a lecture that you only need to listen to? Use our Video to MP3 feature to extract the audio track. This creates a lightweight audio file compatible with any music player, saving storage space on your device.

Video Compressor: Reduce File Size

Large 4K or 1080p video files can be difficult to share via email or WhatsApp. CitosConvert allows you to compress videos by intelligently lowering the resolution (e.g., from 1080p to 720p or 480p). This significantly reduces file size while maintaining acceptable quality for social media sharing.

Why "Client-Side" Matters?

Processing "Client-Side" means the heavy lifting is done by your computer's processor, not a cloud server. This has three huge advantages:

Free MP4 Converter • Extract Audio from MP4 • MOV to MP4 • Video Compressor • Offline Tool

Frequently Asked Questions

Does CitosConvert upload my videos to a server?
Absolutely not. This is a "client-side" tool. We load the conversion engine into your browser, and your computer processes the video locally. Your files never leave your device.
Why does the page say "Loading Video Engine"?
Since we don't use servers, your browser needs to download a powerful tool called FFmpeg (about 25MB) to process videos. This happens only once; subsequent visits will be instant.
Can I convert MOV files from iPhone?
Yes! This is one of our most popular features. You can convert Apple's MOV format to universal MP4 format to view on Windows or Android easily.
Is there a file size limit?
Technically no, but we recommend files under 500MB - 1GB. Since the conversion happens on your device, very large files might slow down your browser or computer depending on your RAM.
How do I reduce video file size?
Select your video, and in the "Resolution" dropdown, choose a lower value (like 480p or 360p). This will drastically reduce the file size, making it easier to share.
