Reduce PDF File Size Tips

Hello Friends..!!

First Method: Reduce File Size in Adobe Acrobat
  1. Launch Adobe Acrobat. Open the PDF file you wish to reduce.

Use the SaveAs command. From the File menu, scroll to Save As... and then select "Reduced Size PDF."

  1. Select the appropriate version compatibility for your requirements.

Third Method: Reducing File Size in Acrobat with PDF Optimizer
  1. Use PDF Optimizer. PDF Optimizer provides finer control for reducing the size of PDF files. In most cases, the default settings are appropriate for maximum efficiency—saving space by removing embedded fonts, compressing images, and removing items from the file that are no longer needed.

  2. Launch Adobe Acrobat. Open the PDF file you wish to reduce.

  3. Save as optimized. From the File menu choose Save As... and then Optimized PDF.

  4. Adjust your settings. Leave as default, or fine-tune your settings as needed.

  2. Export the file. From the File menu, select Export

  3. Set export options. Click the Quartz Filter menu, and select "Reduce File Size."

  4. Save. Select your desired location, then click Save. Your file will be saved in a much-reduced size (see example below).

Fifth Method PrimoPDF
  1. Install PrimoPDF. If you do not have it installed already, download for free at PrimoPDF allows you to print to PDF files right from your browser. Once installed, when you print a page you will have the option to print using PrimoPDF, which will save the file as a PDF.

  2. Open your PDF. Open up the desired PDF file using any application that reads PDF files.

  3. Print the file. Click the "File" menu, then choose "Print," and select PrimoPDF as your printing device.

  4. Select "Properties." Change the downsampling options as required.

  5. Save the file to your desired location.

Sixth Method: Using Windows Compression
  1. Locate your target file. When found, right-click on the PDF file and select "Send To."

  2. Select Compressed (zipped) folder. The file will be a compressed ZIP file (.zip), rather than a PDF file.


Seventh Method: Shrinking Images
  1. Using a PDF editor program, resize your images in your document to make them smaller. If you're using large files to begin with, try resizing the images before inputting them into the PDF. This will help reduce the file size and will sometimes make the images more proportional.

Eighth Method: Mac Export as JPG and Print to PDF in Preview
  1. Open the PDF in Preview.

  2. Select Export, select JPEG, and save the file.

  3. Open the JPG in Preview and Print to PDF. There will be significant reduction in size (and a bit in quality too); the method is only useful for large image PDF files such as maps.


  • Compression programs like WinRAR and 7zip give you the option to compress files even further, thus making the file size even smaller than the standard compression allowed in Windows or Mac.
  • You can also use other PDF editing programs such as Nitro PDF Professional or Foxit Reader rather than Adobe Acrobat to reduce the file size by using "Save As."


  • Adobe Acrobat is not the same thing as Adobe Reader. Adobe Acrobat is a program you must pay for. If you don't have it or don't want to purchase it, choose one of the other methods listed.
