Compress PDF: how it works

Reduce the size of a PDF by rendering its pages as compressed images. Useful for sharing image-heavy documents when keeping selectable text is not essential.

  1. 1

    Choose your PDF.

  2. 2

    Select a compression quality and process the document.

  3. 3

    Compare the result and download the smaller version if it meets your needs.

Before you start: Creates a flattened image PDF. Text search, links, forms and signatures will be lost. Keep your original.

Compress PDF FAQs

Will compression preserve selectable text?

No. This compressor creates an image-based PDF. Text search, links, forms and existing signatures are lost, and some already-optimized PDFs may become larger. Keep the original.

Are my documents uploaded?

The tools listed here process documents in your browser. Selecting a file does not upload its contents to Filestation. Download your output before closing the page; there is no cloud document library.

Are my PDFs encrypted?

The website uses HTTPS to encrypt the connection. Local processing does not automatically password-encrypt your input or downloaded PDF. No website can guarantee 100% security; use a trusted device and keep your original files.

How do I save a PDF on an iPhone?

After creating the result, use Save / Share and choose Save to Files. If a download opens a preview, use the browser’s Share control to save a copy.
