The PDF toolkit for Mac
that asks for nothing.

No uploads. No accounts. No subscriptions.
Compress, merge, split and convert PDFs — offline on your Mac, free forever.

Your PDF is too big
to send.

The upload sites want an account.
Adobe wants a subscription.

Compacto doesn't.

Drop your file. Pick a size. Done in seconds —
entirely offline. No PDF ever leaves your Mac.

Free. Actually free.

Three compression levels. Preview the file size before you save.
No limits. No watermarks.

MIN
Smallest
Maximum compression. Push it as small as it'll go — ideal for email.
MID
Balanced
The sweet spot between size and quality. Works for almost everything.
MAX
Best
Trim the weight, keep the detail. For documents where clarity matters.

Runs natively on Apple Silicon and Intel Macs · macOS 13+
