Private by design

Compress PDF is built to run in your browser. Your documents stay on your device — we do not upload them to our servers or keep a copy of your files.

That is the same privacy model as Filvo image tools: process locally, download, done.

In one sentence

Filvo PDF Compressor shrinks scans and exports in the browser. Tune size versus quality locally — no upload, no account, no watermark.

Filvo vs typical cloud tools

How to compress a PDF for email

Email rejects a heavy scan more often than a bad subject line.

Camera PDFs and slide exports blow past inbox caps. Filvo re-encodes pages locally. This page opens Strong (about 40% JPEG quality) so you start closer to “sendable.”

It is not a guaranteed 5 MB button. Preview a page. If it is still heavy, drop the slider. If it looks muddy, bump quality.

Steps

Drop one unlocked PDF (up to 40 MB). Wait for the preview and size. Download. Keep the master if you will edit again.

Frequently asked questions

Email rejects a heavy scan more often than a bad subject line.

We cannot promise a megabyte target. Strong re-encodes pages as JPEGs. Check the size after compress. Already-tiny files may not drop.
