Compress video
Understand video compression: codecs, quality levels, and size vs quality trade-offs. When to compress, and when to send the original file.
What compression really changes
Before you re-encode, weigh the impact on quality, time, and privacy.
Quality loss
Lossy re-encoding is irreversible. Artifacts, softness, and lost detail cannot be recovered.
Time cost
Compress, send, then decompress lengthens the path. On large files, the network gain often disappears.
Online privacy
Uploading rushes to a third-party service exposes the media. Prefer local processing or a sovereign transfer when you can.
⚙️ Choose the right video compression level
Understand the impact of each level to optimize your videos according to your needs.
High quality
Moderate reduction to preserve maximum visual quality
Heavier file but quality preserved
Balanced
Good compromise between size and quality for web use
Slight acceptable quality loss
Maximum
Aggressive compression to minimize size
Visible quality loss but space gain
