Shrink your PDFs, without sending them anywhere.

Compress PDF files instantly and privately. Processing happens 100% in your browser — your documents never leave your device.

Your files stay private

Everything runs in your browser. Nothing is uploaded, stored, or tracked — so your documents never leave your device.

No file size caps, no sign-ups, no queues. Any PDF works, and the only limit is what your own device can handle.

Compression is powered entirely by your CPU and pursuit of smaller files — we don't spend a cent on processing it.

Three steps, all on your device.

Drag and drop or browse for any PDF file. It stays on your device the entire time.

Slide toward smaller size or better quality — the page images are re-encoded to match.

Grab your compressed PDF instantly. Adjust the strength and re-compress whenever you like.
