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.

What is a PDF compressor?
A PDF compressor shrinks scans and exports so you can email or upload them without a quality disaster.
A PDF compressor reduces file size by re-encoding pages — often the photos inside a scan. Filvo does this in your browser: drop one PDF up to 40 MB, pick Strong, Balanced, or High, and download. Nothing is uploaded to our servers.
The goal is a smaller file that still reads on a phone — for email, portals, and uploads with size caps.
How to compress a PDF
Add a scan, invoice, or export. Choose a preset, then fine-tune with the slider. Preview a page before you save. Strong shrinks more and looks softer; High keeps more detail. Camera scans usually shrink the most. Already-tiny or vector-heavy files may not get smaller — we show “Already optimal” when that happens.
Pages are flattened into images, so you usually cannot select text after compression. Keep the original if you still need copy-paste.
Specific jobs, same compressor
Inbox caps belong on compress a PDF for email. Camera pages: compress a scanned PDF. Portal uploads: compress for upload. Heavy decks: compress a large PDF.
A conservative slider lives on compress without losing quality. Receipts: compress an invoice PDF. Same engine — different starting quality and copy.
Who should compress PDFs online?
Anyone hitting an email or portal size cap. After you shrink a file, you can merge it with others or convert pages to JPG.
Why use a private PDF compressor?
Invoices and IDs should not sit on a random server. Filvo compresses locally, with no account and no watermark. Password-protected PDFs need to be unlocked first.

More ways to compress a PDF
Same in-browser compressor — pages written for email, scans, or a gentler slider.
Compress a PDF for Email
Inboxes still cap attachments. This page starts on Strong so scans have a better chance of going through.
Compress a Scanned PDF
Phone photos inside a PDF are the usual reason the file is huge. Strong is already selected.
Compress a PDF for Upload
Application and tax portals still cap uploads. Balanced is the starting point — Strong if you still need more.
Compress a Large PDF
40-page scans and slide decks stall email. This page assumes the file is already too big.
Compress a PDF Without Losing Quality
High (about 82%) is already selected so you can see whether savings are worth what you see.
Compress an Invoice PDF
A stack of photo-receipts is an email problem. Balanced keeps stamps readable while cutting the fat.
