Why Use Video Compressor?
Up to 90% Size Reduction Using H.264 Perceptual Coding
H.264 (standardized as ITU-T H.264 / ISO/IEC 14496-10 AVC) uses perceptual coding models that discard visual information the human eye cannot detect. According to Cisco's Annual Internet Report, video accounts for 82 percent of all internet traffic, and H.264 remains the dominant codec making that traffic manageable. Heavy compression at 480p can shrink a one-gigabyte 4K recording to under one hundred megabytes while remaining perfectly watchable on a phone screen.
Three Compression Tiers Matched to Real-World Limits
Light compression removes 30 to 50 percent of the file weight, enough to speed up cloud uploads without touching visual quality. Medium drops 50 to 70 percent and is the sweet spot for most sharing scenarios. Heavy pushes toward 90 percent reduction, sized for email attachment limits (Gmail caps at 25 MB according to Google's own documentation) and WhatsApp video limits (16 MB on most networks).
Sized for Every Platform's Upload Ceiling
The Radicati Group's Email Statistics Report estimates 347 billion emails are sent daily, and attachment limits remain the single biggest friction point for video sharing. Discord caps uploads at 25 MB for free users. Slack limits files to 1 GB but throttles upload speed. Instagram recommends under 650 MB. This compressor produces files that clear every platform's gate without a second pass.
Visually Lossless at Light and Medium Settings
Double-blind studies on video compression quality, including the Netflix VMAF (Video Multi-Method Assessment Fusion) metric, demonstrate that H.264 at CRF 18 to 23 produces output indistinguishable from the source on consumer displays. Light and medium compression operate in this range, which is why the result looks identical to the original on phones, laptops, and televisions.
Common Use Cases
Perfect for any file size challenge
Email Attachments
Compress videos to fit email attachment limits (usually 25MB). Send video messages without bouncebacks or failed deliveries.
WhatsApp & Messaging
Shrink videos for WhatsApp (16MB limit), Telegram, and other messaging apps. Share moments without quality warnings.
Save Storage Space
Reduce video file sizes to save space on your phone, computer, or cloud storage. Keep more videos without buying more storage.
Faster Uploads
Compressed videos upload faster to YouTube, social media, and cloud storage. Spend less time waiting on slow connections.
How It Works
Upload Your Video
Drag and drop your video file. We support MP4, MOV, AVI, MKV, WebM formats up to 2GB in size.
Select Compression Level
Choose Light for minimal reduction with best quality, Medium for balance, or Heavy for maximum compression when size is critical.
Choose Resolution
Keep original resolution or downscale to 1080p, 720p, or 480p for additional size savings without visible quality loss on smaller screens.
Download Compressed Video
Download your smaller video file ready for sharing, uploading, or storage. See the size reduction percentage.
Pro Tips for Better Compression
Trim First
Trim your video before compressing. Shorter videos compress faster and achieve smaller final sizes. Don't compress footage you'll cut anyway.
Match Viewing Device
If the video will only be viewed on phones, 720p or even 480p is plenty. Save file size by matching resolution to how it will be watched.
Test Heavy Compression
When using heavy compression, preview the result before sharing. Most videos look fine, but complex scenes with lots of motion may show artifacts.
Check Original Compression
Videos from phones are already well-compressed. If your video doesn't shrink much, it may already be optimized. Try resolution reduction instead.
