Compress PDF

▸About this tool

Compress one PDF or several at once. Choose Basic, Balanced, Max, or Strong, then download a smaller PDF or a ZIP of all your files.

▸Privacy and details

Your files never leave your device.

Fast browser processing with no account required.

Optimized for desktop and mobile with accessible controls.

▸How to use
  1. Drop one or more PDFs into the upload area, or click to browse.
  2. Choose a preset: Basic, Balanced, Max, or Strong.
  3. For multiple files, add or remove any PDF before you start.
  4. Click Compress PDF and wait for browser-side processing.
  5. Download the compressed PDF, or a ZIP if you compressed several at once.
▸Why use this tool

PDFs grow because of embedded images and scans. Basic runs a lossless cleanup with no visual change. Balanced and Max re-encode images at lower quality for smaller files. Strong re-encodes embedded images in place for the smallest size on scanned documents. Drop several PDFs to compress them in one batch and get a ZIP back.
