Compress a PDF without giving up your privacy
Most online PDF compressors upload your documents to their servers. GetFormat works differently: all compression happens in your browser. Your contracts, invoices, quotes or scanned files never leave your computer — perfect for sensitive documents.
It's also faster: no upload or download wait. Compression is instant and works even offline once the page has loaded. Scanned or image-heavy PDFs can be reduced by 50–80%, making them easy to email (under the 10 MB limit) or attach to a form.
Frequently asked questions
Is compressing a PDF free?
Yes, no sign-up. The Pro plan adds unlimited batch processing to compress many PDFs at once.
Is my PDF uploaded anywhere?
No, never. Everything happens locally in your browser — ideal for confidential documents.
Which PDFs compress best?
Scanned or image-heavy PDFs. Choose “Maximum” for the smallest size, or “Light” to preserve quality.
Is quality preserved?
You choose the level. Compression re-encodes the images in the PDF; text stays readable and the visual result stays close to the original.
