How to compress a PDF
Reduce PDF file size without losing quality. Compress PDFs in your browser. No upload, private.
To compress a PDF, open our Compress PDF tool, add your file, and download the smaller version. Processing runs in your browser, so your document stays on your device.
Step 1: Go to the Compress PDF tool. Step 2: Select your PDF (or drag and drop). Step 3: Wait for the optimised file to be generated, then download. No signup or server upload required.
We use client-side processing so your files never leave your computer. That’s ideal for confidential or work documents compared to tools that upload to the cloud.
