Features That Make a Difference
MP4 Format - Universal Compatibility
MP4 (MPEG-4 Part 14) is the most widely supported video format in the world. Using H.264 video codec and AAC audio codec, MP4 files play on virtually every device and platform - smartphones, tablets, computers, smart TVs, game consoles, and all modern web browsers. Perfect for YouTube uploads, social media sharing, email attachments, and general-purpose video storage. Our MP4 encoder includes faststart optimization for instant web playback.
MOV Format - Apple Ecosystem
MOV is Apple's native QuickTime format, offering excellent quality and seamless integration with macOS, iOS, and Apple applications like Final Cut Pro and iMovie. While MOV files tend to be larger than MP4, they maintain exceptional quality and support advanced features like multiple audio tracks and chapters. Ideal for video editing workflows, professional content creation on Mac, and sharing videos within the Apple ecosystem.
AVI Format - Windows Standard
AVI (Audio Video Interleave) is Microsoft's multimedia container format, widely supported on Windows systems. Using MPEG-4 video and MP3 audio, AVI files offer good compatibility with Windows Media Player and older video editing software. While AVI produces larger file sizes compared to MP4, it provides reliable playback on Windows PCs and is excellent for archiving videos with minimal compression.
WebM Format - Web Optimized
WebM is a modern, open-source format specifically designed for web playback. Using VP9 video codec and Opus audio codec, WebM achieves superior compression compared to MP4, resulting in smaller file sizes with comparable quality. This makes WebM ideal for website videos, streaming content, and bandwidth-sensitive applications. Supported natively by Chrome, Firefox, and Edge browsers, WebM is perfect for HTML5 video elements and progressive web apps.
MKV Format - High Quality Container
MKV (Matroska Video) is an advanced multimedia container that supports virtually any video and audio codec. Known for preserving maximum quality, MKV files can contain multiple video tracks, audio tracks in different languages, subtitles, and chapter markers all in a single file. Perfect for high-quality video archiving, Blu-ray rips, anime with multiple subtitle tracks, and content requiring multiple audio languages. Our MKV encoder uses high-quality settings (CRF 18) to maintain exceptional visual fidelity.
FLV Format - Legacy Streaming
FLV (Flash Video) was the standard for online video streaming before HTML5 became mainstream. While newer formats have largely replaced FLV, it remains relevant for legacy systems, older websites still using Flash players, and certain specialized applications. FLV files are highly compressed and optimized for streaming over slower connections.
Professional Encoding Settings
Each format uses optimized encoding parameters tailored to its strengths. MP4 and MOV use H.264 at CRF 23 for balanced quality and size. AVI uses MPEG-4 for Windows compatibility. WebM uses VP9 for maximum web compression. MKV uses high-quality CRF 18 for archival purposes. All formats include appropriate audio codecs (AAC, MP3, or Opus) at optimal bitrates.
Batch Conversion Ready
While our interface processes one video at a time for simplicity, you can easily convert multiple videos sequentially. Each conversion maintains full quality with format-specific optimizations, ensuring professional results every time.
No Quality Loss in Lossless Conversions
When converting between compatible formats (e.g., MP4 to MOV), our encoder preserves maximum quality. Even when re-encoding is necessary, we use high-quality settings to minimize visible quality degradation.
Smart Format Detection
Our system automatically detects your input video format and applies the most appropriate conversion pipeline, ensuring compatibility and optimal results regardless of the source format.
Optimized File Size Limits
Process videos up to 100MB, covering most short to medium-length videos at standard quality. This ensures fast, reliable processing without server overload.

Common Use Cases
Social Media Cross-Platform Publishing
Different social media platforms prefer different video formats. Convert your master video to MP4 for Facebook and Instagram, WebM for Twitter's web interface, and MOV for Apple News and iMessage sharing. Reach your audience everywhere without quality loss or compatibility issues.
iPhone Videos to Android Sharing
iPhones record videos in MOV format using HEVC codec, which often causes playback issues on Android devices and Windows PCs. Convert iPhone videos to MP4 with H.264 codec for universal compatibility, ensuring your videos play smoothly when shared with non-Apple users.
Website Video Optimization
Convert videos to WebM for modern web browsers to reduce bandwidth usage by 20-40% compared to MP4, or provide both WebM and MP4 versions for maximum compatibility. Faster loading means better user experience and improved SEO rankings.
Video Archive Preservation
Convert important videos to MKV format for long-term archival storage. MKV preserves maximum quality while supporting multiple audio tracks (original language + dubbed versions), subtitle tracks in various languages, and chapter markers for easy navigation.
Legacy Format Modernization
Convert old FLV, WMV, or RM files to modern MP4 format. These legacy formats were common in the 2000s but lack support on modern devices. Converting to MP4 ensures your old videos remain watchable on current and future devices.
Video Editing Workflow Preparation
Convert footage from various sources (cameras, phones, downloads) to a consistent format before importing into your video editor. This prevents compatibility issues, reduces editing lag, and ensures color and quality consistency across your project.
Email-Friendly Video Formats
Convert large MOV or AVI files to MP4 with optimized settings, reducing file size while maintaining quality. Smaller MP4 files are easier to share via email and messaging apps that have attachment size limits.
Gaming Console Playback
PlayStation, Xbox, and Nintendo Switch have specific format requirements. Convert videos to MP4 with H.264 codec for reliable playback on gaming consoles connected to TVs, perfect for watching tutorials, movies, or personal videos on the big screen.
Dashcam and Security Camera Footage
Dashcams and security cameras often record in proprietary or unusual formats. Convert to standard MP4 for easier viewing, editing, and sharing with insurance companies or authorities if needed.
Presentation and Training Videos
Convert training videos to MP4 for inclusion in PowerPoint or Google Slides presentations, or convert to WebM for embedding in corporate intranets and learning management systems with reduced bandwidth consumption.
Optimization Tips
Getting the best results from video conversion requires understanding when to use each format. **Use MP4** for maximum compatibility - it's supported everywhere and should be your default choice for general-purpose videos, social media sharing, mobile devices, and web hosting. MP4 with H.264 codec strikes the perfect balance between file size and quality. **Choose MOV** only if you're staying within the Apple ecosystem and need features like multi-track audio or plan to edit the video in Final Cut Pro or iMovie. MOV files are larger but preserve quality excellently. **Select AVI** for Windows-only environments or when working with older video editing software that doesn't handle MP4 well. Keep in mind AVI files are significantly larger. **Pick WebM** for website embedding when you need the smallest possible file size without visible quality loss. WebM's superior compression saves bandwidth and improves page load times. Always provide an MP4 fallback for browser compatibility. **Use MKV** for archiving high-quality videos, storing movies with multiple audio languages and subtitle tracks, or any scenario where quality is more important than file size. **Avoid FLV** unless you specifically need it for legacy Flash-based systems. For all conversions, start with the highest quality source video available - converting from a low-quality source won't improve quality, it can only maintain or reduce it. Keep your original files as backups. Files up to 100MB are supported, covering most videos up to 5-8 minutes at 1080p or 15-20 minutes at 720p quality. If you have larger files, consider compressing them first.
Privacy & Security
Video files often contain personal, sensitive, or proprietary content - family memories, business presentations, confidential training materials, or creative work. We understand the trust you place in us when uploading your videos, and we take that responsibility seriously. Every video upload and download happens over encrypted HTTPS connections, preventing interception during transfer. Files are processed on secure servers with strict access controls - our system handles the conversion, but no human ever sees or accesses your video content. Videos are temporarily stored in isolated processing containers and are automatically and permanently deleted from our servers within one hour after processing completes, usually much sooner. We don't create backups, we don't log video content, and we don't use your videos for any purpose beyond the conversion you requested. No account creation means no email collection, no personal data storage, and no tracking of what videos you convert. You remain completely anonymous. Our service complies with GDPR, CCPA, and international privacy standards. For additional security with extremely sensitive content, you can convert videos during off-peak hours when server load is lower, though our security measures are consistent 24/7. We will never sell, share, or monetize your video data - our business model is advertising-supported, not data-driven.
