Quick guide and practical context
Compression control with expected final size
The compression slider lets you choose lighter or stronger reduction depending on your quality target.
Before processing, the tool shows an estimated output size based on duration and target profile to help you decide quickly.
- Lower compression for better quality retention.
- Medium compression for day-to-day uploads.
- Higher compression for stricter file-size limits.
- Batch queue for handling several videos at once.
Privacy and performance notes
Videos are processed locally in the browser by default, without automatic upload to a backend service.
Large high-resolution videos demand more RAM and CPU, so conversion time depends on your device performance.
