Compress PDF Online

Reduce the size of scanned or image-heavy PDFs. Each page is re-rendered as a compressed image, which can shrink files a lot but means text will no longer be selectable.

Supported files and privacy

Formats: PDF. Maximum file size: 50 MB per file. Files are processed in your browser and are not uploaded to our servers.

How to use PDF Compressor

  1. Select your PDF.
  2. Choose a compression level.
  3. Click Compress.
  4. Compare sizes and download.

Good to know

  • Pages become images, so text is no longer selectable or searchable.
  • A final size cannot be promised before processing.
  • PDFs that are already small may not shrink.

Frequently asked questions

Will text stay selectable?

No. This version rasterizes pages. A server-side compressor that preserves text is planned.

Is my PDF uploaded?

This tool runs in your browser, so your file is not uploaded to our servers.
