Way 2. Convert PDF to A4 Size in Adobe Acrobat

Even if you are encountering a PDF editor for the first time, you must have seen many posts or websites recommending Adobe Acrobat. Can you resize a PDF in Adobe Acrobat? Of course, as a professional PDF editor, Adobe Acrobat enables you to perform a wide range of PDF tasks, including but not limited to resizing PDFs, annotating PDFs, protecting PDFs, and more. Here are two options for converting a PDF to A4 size in Adobe Acrobat. Let’s have a look.

Option 1. Change page size using Print to PDF

Step 1. Launch Adobe Acrobat Pro and import the PDF you want to resize.

Step 2. Click File and select the Print option. Then, open the Printer list and select the Adobe PDF option for virtual printing. Next, choose the Fit or Shrink oversized pages option under Page Sizing & Handling.

Step 3. Click the Page Setup button in the lower-left corner, open the Size list, and choose A4. Then, click OK to save the changes.

Step 4. Finally, click the Print button.

Option 2. Use Preflight

If you don’t want the content scaled, Preflight is the better choice.

Step 1. Go to Tools > Print Production > Preflight.

Step 2. In the Preflight window, click the Fixup option (a wrench icon) and type Set page size in the search box.

Step 3. Next, you can choose the following three options: Scale pages to A4, Set page geometry boxes to A4 size, or Scale pages to specified size. Then, click Fix.

Step 4. At last, save the PDF file in A4 size.

Between the two options, Option 1 is adaptable to almost all documents, such as letters, reports, and ebooks. If you notice that scaling ruins something critical, like a form field moving or the map scale becoming wrong, switch to Option 2.
