How to compress a PDF
- Select or drop one PDF file.
- Choose Recommended, Extreme or Less Compression.
- Select Compress PDF and wait for every page to process.
- Compare the sizes and download the compressed PDF.
Which compression level should I choose?
Recommended is suitable for most sharing and email tasks. Extreme prioritizes a smaller file. Less keeps more visual detail for documents containing charts, screenshots or small text.
Privacy and limitations
Your PDF stays on your device. Compression happens locally using bundled browser libraries. Because pages are rebuilt as images, keep the original whenever you need selectable text, working links, forms, layers, accessibility tags or digital signatures.
