Whether you are optimizing for the NBN, preparing myGov submissions, or sharing files across Australia's vast distances, this tool keeps your files light and quick to transfer — even on regional, fixed-wireless, and satellite connections, with no upload required.

Frequently Asked Questions
Can I compress a PDF to exactly 200KB?
The tool tries to reach your selected target as closely as possible. Exact results depend on the original PDF content, especially scanned pages and large images.
Is this browser-based PDF compressor private?
Yes. PDF compression runs in your browser, so your documents are not uploaded to our servers.
Will PDF quality change?
To reach smaller targets, the tool may reduce image detail inside the PDF. Text and layout remain readable for most everyday upload and sharing needs.
Can I compress multiple PDFs at once?
Yes. You can add multiple PDF files, compress them in one batch, and download the results together.
