Getting started

Make your first result with Compress PDF, then use the same open, configure, and save pattern for the other tools.

Open a PDF

  1. Install DipperPDF and open it.
  2. Choose Compress PDF in the app sidebar.
  3. Drop a PDF into the file area, or click the area to choose a file from Finder. Command+O also opens the file chooser.
  4. Wait for the filename and page count to appear.

Most tools accept one PDF at a time. Merge PDFs accepts multiple files. Encrypted PDFs must go through Unlock PDF first, even if they open without asking for a password.

Make and save a result

  1. Choose Balanced compression.
  2. Click Compress PDF and wait for the size comparison.
  3. Click Save PDF…, choose a name and location different from the source, and save.
  4. Open the saved copy to check the pages and image quality before sharing it.

Your source stays unchanged. DipperPDF prevents saving over the imported source, including through an aliasing file path. Choose a fresh filename for your result.

Some tools prepare a result and show a separate save button. Others process and open the save dialog in one action. Split PDF asks for a folder and creates a new subfolder for its outputs.

Work with pages

Rotate PDF, Remove Pages, and Extract Pages use thumbnails:

  • Click a page to select it.
  • Command-click to add or toggle pages.
  • Shift-click to select a range.
  • Use Select All or Command+A to select every page when a selection tool is active.

Page-range controls in other tools use the PDF's page positions, beginning with 1. Printed page numbers on a document may differ.

Continue with another tool

Save the result, choose your next tool, and import that saved copy. For example, merge documents, save the merged PDF, then add page numbers.

Changing input or processing settings can clear a prepared result; prepare it again before saving. Let a job finish or cancel it before making changes. Switching tools cancels work in the tool you leave.

Review important outputs in a PDF viewer. Rewriting a PDF can invalidate digital signatures or alter bookmarks, tags, forms, and other advanced features.
