Error: Bad parameter while deleting pages from a PDF

When you try to delete a page from a PDF, you see the error message “Bad Parameter.” The same error message may also occur when you try to insert or add a page to the PDF.

The “Bad Parameter” error occurs when Acrobat finds some problem with the underlying structure of the tags in the PDF file. Try the following solutions.

Solution 1: Combine the PDF with another PDF

  1. Launch Acrobat, and then choose File > Create > Combine Files into a Single PDF

  2. Click the Add Files menu and choose Add Files.

  3. Browse and select the PDF file that shows the "Bad Parameter" error, and then click Open.

  4. Click the Add Files menu and choose Add Files.

  5. Browse and select another PDF file, preferably a one-page, blank PDF file, and then click Open.

  6. Click Combine or Combine Files. The selected files are combined into a single PDF, and the file (Binder1.pdf) is opened in Acrobat.

  7. Save the file. Select all the pages you added to the PDF using the Combine Files operation (the pages of another PDF you selected while combining files). Delete the selected pages:

    • In Acrobat DC/2017, choose View > Tools > Organize Pages > Open. Select the pages you want to delete, and then click the Delete icon or press Delete.
    • In Acrobat XI, choose View > Tools > Pages. Select the pages you want to delete, and then click Delete in the right pane or press Delete.
  8. Save the file again. To see if the error still occurs, try to delete a page from the PDF.

Solution 2: Export the PDF as PostScript file and then convert it into a PDF using Distiller

This solution works well for a PDF without interactive elements, such as multimedia or form fields.

Don't try this solution if the PDF has interactive elements; those elements may not work correctly after exporting the PDF to PostScript and then converting it back to PDF.

  1. Open the PDF in Acrobat.

  2. Choose FileExport To > PostScript.

  3. In the Save As PDF dialog box, enter a different name for the file, and then click Save.

  4. In the folder where you saved the PostScript file, right-click the file and choose Open with Adobe Acrobat Distiller.

    Acrobat Distiller converts the PostScript file into a PDF file. The PDF file is saved in the same folder.

  5. To see if the error still occurs, open the PDF file in Acrobat and try to delete, insert, or add a page.
