      2. Click Save to finalize the export.

      Note: If you want your to be exported as non-editable, check the "export all text as curves" option!

      Optimizing PDFs using Adobe PDF and Preflight

      If your PDF contains high-resolution images or numerous pages, it may not upload correctly in Flipsnack. To optimize the file size, follow these steps using Adobe PDF:

      1. Open your PDF in Adobe Acrobat.

      2. On the left sidebar, click on "All Tools".

      3. Search for "Use Print Production" (you may need to click "View More" to find it).

      4. Once inside Print Production, select the Preflight option.

      5. In the new Preflight window, go to the Profiles tab, navigate to the PDF Fixups section, and choose:

        • Downsample image resolution to 150 ppi (bitmaps to 300ppi).

      6. Click Analyze and Fix to start the process.

      7. Save the optimized PDF with a new name.

      8. Click Save, and the optimization process will begin.

      9. Once completed, upload the optimized file to Flipsnack.

      Example: A 450 MB file optimized through this process resulted in a file size of approximately 65 MB.

       
      By applying these methods, you can prevent common upload issues and ensure a smooth experience while using Flipsnack.
