Why Compress Videos?

Video files are the largest files most people deal with. A single minute of 4K video can exceed 500MB. Compressing videos is essential for:

• Email and messaging: Fit videos within attachment size limits for email (25MB), WhatsApp (16MB), and Discord (8-25MB).
• Faster uploads: Smaller files upload faster to YouTube, Instagram, TikTok, and cloud storage.
• Website performance: Compressed videos load faster, reducing bounce rates and improving SEO.
• Storage management: Free up space on phones, cameras, and hard drives.
• Streaming optimization: Lower bitrate videos stream more smoothly on slower connections.

Supported Video Formats

XConvert Video Compressor handles all major video formats:

• MP4 — Most widely supported format. Uses H.264 or H.265 codecs.
• WebM — Open format optimized for web. Uses VP8 or VP9 codecs.
• MOV — Apple's QuickTime format. Common for iPhone and Mac recordings.
• AVI — Older format with broad compatibility.
• MKV — Flexible container supporting multiple audio and subtitle tracks.
• FLV, WMV, MPEG, 3GP — Full support for legacy and mobile formats.

You can compress while keeping the original format, or convert to MP4 or WebM during compression.

Frequently Asked Questions

How much can I reduce a video file?

Typical results range from 50-90% reduction depending on the source. A 500MB raw video can often be compressed to 50-100MB with minimal visible quality loss. Videos with lots of motion compress less than static content.

Will compression reduce video quality?

At moderate settings (CRF 20-23), most viewers can't distinguish compressed from original. Quality loss becomes noticeable at very high compression levels. XConvert gives you full control to find the right balance.

What's the best format for compressed video?

MP4 with H.264 for maximum compatibility — plays on virtually every device and browser. MP4 with H.265 for maximum compression — 30-50% smaller files but requires newer devices. WebM with VP9 for web embedding.

How do I compress a video for Discord?

Upload your video and set the target file size to 8MB (free) or 25MB (Nitro). Reduce resolution to 720p for best results at small file sizes.

Can I compress without changing resolution?

Yes. Use bitrate or CRF compression without changing resolution settings. This optimizes encoding efficiency without altering video dimensions.

Is there a file size limit?

Free users can compress videos up to 1GB each. There's no limit on the number of files per session.

Is my data secure?

Yes. All uploads use TLS encryption. Files are automatically deleted after processing. We never store, share, or access your videos.

Does it work on mobile?

Yes. XConvert works in any modern browser on Windows, macOS, Linux, Android, and iOS — no app installation required.
