PDF Compressor Online

Reduce image-heavy PDFs by rebuilding pages at a smaller image size.

High quality keeps sharper pages. Balanced is best for most uploads. Maximum compression creates smaller files with softer page images.

When this tool helps

This tool is most useful when a PDF is too large for a job portal, school system, email attachment, or government upload form.

How to get a good result

  1. Choose the PDF file.
  2. Select a JPEG quality and maximum page width.
  3. Run compression and compare the before and after sizes.
  4. Open the downloaded PDF to confirm pages are readable before submitting it.

Scans and photo-based PDFs usually shrink well. Text-only PDFs may not shrink much because there are fewer heavy images to reduce.

Privacy and limits

The PDF is opened in your browser and rebuilt locally for this workflow. The page does not require a login or ask you to upload the file to an account.

The compressed PDF is rebuilt from rendered pages, so selectable text, form fields, comments, and embedded links may be flattened. Keep your original file if you need an editable copy.
