3. Download the compressed video instantly.

Compression Presets

Preset	Size Reduction	Quality	Best For
Light	30-50%	Near-original	Archival, high-quality sharing
Medium	50-70%	Good	Social media, email
Heavy	70-90%	Acceptable	Messaging apps, previews
Custom	Variable	User-defined	Specific size targets

Practical Tips

• Start with medium compression and check the quality. You can always re-compress the original at a heavier setting if needed.
• Lower the resolution (e.g., 4K to 1080p) for the biggest size savings with minimal perceived quality loss on smaller screens.
• H.265/HEVC codec produces smaller files than H.264 at the same quality, but check that your target platform supports it.

How much can I compress a video?

Typical results range from 50-80% size reduction. A 500 MB video can often be compressed to 100-150 MB without noticeable quality loss, similar to what HandBrake achieves.

Does compression reduce video resolution?

Not by default. Compression reduces bitrate (data per second) while keeping the same resolution. You can optionally downscale resolution for even smaller files.
