You can reduce a document’s file size by compressing the PDF. Many PDF programs include a built-in compression option, and there are also reliable online tools available.

To compress a PDF using an online tool (such as Adobe Acrobat):

1. Make sure your document is saved on your computer as a PDF file.
2. Go to Adobe Acrobat’s Compress PDF website.
3. Upload your file. 
4. Select a compression level (High, Medium, or Low), depending on how much you want to reduce the file size and maintain quality.
5. Download the compressed PDF.

Tip: Higher compression results in a smaller file size but may reduce image quality.
