Modern smartphones record video in stunning quality. A 60-second 4K video from a recent smartphone can easily hit 400MB — far too large to send over WhatsApp, attach to an email, or upload quickly to social media. Video compression reduces file size while keeping the video looking good enough for its intended use.
Here's the practical guide to compressing video for every platform, completely free.
Open ConvertDriver's free video compressor in your browser.
Upload your video by dragging it in or clicking Browse. A preview will appear so you can see what you're working with.
Choose a compression level (Low/Medium/High) or click a platform preset (WhatsApp, Email, Instagram, etc.).
Click Compress Video. The tool shows you the original vs compressed size and savings percentage.
Download your compressed video — ready to share anywhere.
💡 WhatsApp tip: WhatsApp's 16MB limit applies to standard accounts. If you're using WhatsApp Business, the limit is 2GB. For a 1-minute video at High compression, most modern smartphones produce output well under 16MB.
Yes, but minimally. At Medium and High compression, audio is re-encoded at a slightly lower bitrate, but it remains fully intact and clearly audible. The difference in audio quality between uncompressed and High compressed video is much less noticeable than the visual quality difference.
Your video never leaves your device. No signup, no watermark.
