Compress PDF locally

Reduce many image-heavy PDFs in your browser with adjustable JPEG quality and render resolution.

No files selected

Files stay in this browser and are never uploaded.

When this tool is useful

Scans, slide exports, and photo-heavy documents that are too large to email or archive conveniently.

How local processing works

Each page is rendered locally, encoded as JPEG, and placed into a new PDF at the original page size.

How to use it

  1. Choose the source files.
  2. Review the available settings and page order.
  3. Process locally, inspect the result, and download it.

Important limitations

This is lossy raster compression: selectable text, links, forms, annotations, signatures, and layers become pixels. Some PDFs may become larger.

Private by design

Your files stay in this browser. The tool does not upload the source or output to our servers.

Questions and answers

Does this tool upload my files?

No. Processing happens in your browser; closing the page clears the working session.

Will the output always match the source exactly?
