The formats that eat your disk, handled together.
PDF, Office and images

Quality presets
Choose a quality preset instead of chasing settings: from visually identical results to maximum savings, one decision per batch.
Disk space, checked first
A pre-check estimates how much space a batch can free, so you know the numbers before you start.

Compression runs on your local CPU. No uploads, no accounts, no waiting in someone else's queue.
Pricing

No subscription, no account, nothing to renew.

Will I lose quality?
The quality preset you choose controls the trade-off. Pick the one that fits the job before the batch runs.
How does the disk pre-check work?
Before compressing, the app estimates how much disk space the batch can free, so you can decide with the numbers in hand.
