Frequently Asked Questions

How much smaller will my video get?
Results depend on source bitrate and chosen quality preset. Most clips shrink 40–70% with balanced presets while remaining watchable on phones and laptops.
Can I target a specific file size?
The web tool offers quality presets for quick results. For exact megabyte targets and batch compression, use Seer Video or Seer Pro in the Seer app ecosystem.
Is compression done on my device?
SeerKits attempts local compression first so your footage never leaves your machine. Larger or exotic codecs may use a temporary secure pipeline with immediate deletion after download.
