Two ways to reduce video file size

1. Lower quality setting: reduces bitrate, keeps same resolution. 2. Lower resolution: reduces pixel count (and bitrate naturally). Combining both gives the smallest files.

How to Get Started

1.
Upload your large video — Drop any video format into the tool.
2.
Use quality slider — Start at 65% and go lower until you reach your target size. Each 10% drop reduces size roughly 15-25%.
3.
Optionally downscale — Select 720p or 480p from the resolution dropdown for even smaller output.

Frequently Asked Questions

How much can I reduce video file size?

Typical reduction: 50-80% at 65% quality (same resolution). With 720p downscale at 65%: 80-90%. With 480p at 50%: 90-95%.

What's the smallest I can make a video?

Use 360p resolution at 5% quality for maximum compression. Quality will be poor but file sizes will be tiny.

Can I reduce size without visible quality loss?

At 80-90% quality, quality loss is nearly invisible. Below 60%, you may notice softness and artifacts on complex scenes.

Does lowering resolution help more than lowering quality?

Both help significantly. For maximum size reduction, lower resolution first (more impactful), then lower quality.
