Frequently Asked Questions

Video conversion speed depends on several factors:

• File size: Larger files take longer to process
• Output format: Some formats (like H.265) are more computationally intensive
• Device performance: Your CPU/RAM directly affects conversion speed
• Browser: Chrome and Edge typically offer the best performance
• First load: The first conversion downloads FFmpeg (~30MB), making it slower

Tips to speed up conversions: Close other tabs, use a desktop browser, and consider converting smaller files or using lower quality settings for faster processing.

VideoConvert supports 50+ video formats, including:

Yes! After your first use, VideoConvert can work offline:

• The FFmpeg WebAssembly library (~30MB) is cached in your browser after the first conversion
• Once cached, you can convert videos without an internet connection
• All processing happens locally in your browser, so no internet is needed for conversions

Note: You need an internet connection for the initial page load and to download FFmpeg on your first use.

File size limits depend on your device's available memory:

• Typical limit: Files up to 1GB work well on most devices
• Large files (1-2GB): May work but will be slower and consume significant memory
• Very large files (>2GB): May cause browser crashes or performance issues

Tips for large files:

• Close other browser tabs and applications to free up memory
• Use a desktop computer rather than a mobile device
• Consider splitting large files into smaller segments first
• Use lower quality settings to reduce processing requirements

Yes, but with some limitations:

• Mobile browsers support video conversion, but performance is slower than desktop
• Smaller file size limits due to mobile device memory constraints
• Battery drain during conversion (especially for larger files)
• Some advanced features may work better on desktop

Recommendation: For best results, use a desktop browser (Chrome, Edge, or Firefox) on a computer with adequate RAM.

The first conversion requires downloading the FFmpeg WebAssembly library:

• Download size: ~30MB of FFmpeg files
• One-time download: These files are cached in your browser
• Subsequent conversions: Much faster because FFmpeg is already loaded

You'll see a "Loading conversion engine..." message during the initial download. This only happens once per browser.

Choose quality based on your needs:

• High Quality: Best for archiving or professional use. Larger file size, best visual quality.
• Standard Quality: Balanced option for most uses. Good quality with reasonable file size.
• Low Quality: Smallest file size, faster conversion. Good for quick sharing or email attachments.

Quick Presets: Try our preset buttons (YouTube, Instagram, Discord, Email) for optimized settings for specific platforms.
