Frequently Asked Questions
Everything you need to know about trimming videos online
How do I reduce video file size without losing quality?
- Our smart video compressor typically reduces file sizes by 50% to 90% while maintaining excellent visual quality. For example, a massive 500MB video can become a web-friendly 50MB file with an imperceptible difference in clarity. Choose our "Balanced" preset for the best size-to-quality ratio.
How do I compress a video to an exact target file size?
- Yes! If you need to hit a strict file size limit, simply enter your desired target size in megabytes (MB). Our compressor will automatically calculate and apply the optimal bitrate and settings to achieve that exact size.
How to compress a video for WhatsApp, Discord, or Email?
- Use our built-in platform presets. The WhatsApp preset automatically optimizes your video for the 16MB limit, while the Email preset targets the standard 25MB attachment limit, giving you the best possible quality for those platforms instantly.
Can I compress MP4, MOV, and WebM video files?
- Yes, we support all major formats. Compressing to MP4 offers the best compatibility across all Apple and Android devices. Converting and compressing to WebM provides smaller file sizes that work best for web browsers and websites.
Does this free video compressor add a watermark?
- No. Our online video size reducer is completely watermark-free. You get a clean, professionally compressed video ready for sharing, uploading, or client delivery without any unexpected branding.
