Below are the most common causes for a scanned document to be too big in size when saved as a PDF file. Most users will notice the PDF is too large when they try sending the PDF in e-mail and realize it exceeds the allowable size. Most e-mail services don't allow attached files larger than 3 to 5 MB.
Re: DWG to PDF images not showing up unlike BarbM, having the image on the correct layer is not my issue unfortunately (I wish it was cause I could fix that). I have been in contact with Autodesk Support, they want a sample drawing to see if they can reproduce the same problem, they should be able to figure it out after which I'll post a reply. The DMG image format is by far the most popular file container format used to distribute software on Mac OS X. Here’s how to convert a DMG file into an ISO file that can be mounted on a Windows PC.
DPI
The dots per inch (DPI) of the scanned image is often the primary cause of a large PDF file. By default, most scanners will scan images at 300 DPI, which is the minimum DPI for any image that is printed after scanned. However, for a PDF that is for screen reading the DPI should be 72.
Saving as color
Because most scanned objects are text-only documents, they do not need to be in color. Make sure that your images are black and white and not color.
Color settings
Even after setting your scanner to black and white some scanner software may keep other color settings enabled. After setting the image to black and white make sure that any color settings such as 'Color Depth' are also decreased.
PDF convert
If the above suggestions have been done, and the image size is small, but the PDF is still large, the culprit may be the PDF software performing the conversion. Make sure the settings in the software that converts the PDF are properly set. Again, we suggest making sure the PDF resolution is 72 DPI. PDF programs may also have different ways to save a PDF. For example, in PrimoPDF you can save the PDF as 'Screen,' 'eBook,' 'Print,' and 'Prepress.' For most users the PDF file needs to be viewed on the screen, so the 'Screen' setting could be used.
Adobe Acrobat Pro
If you have the non-free version of Adobe Acrobat Pro, this program can also shrink the PDF by using the Reduced in size option under Document. Alternatively, you can use the PDF Optimizer in Advanced.
Other e-mail suggestions
If you've tried the above suggestions and the file size is still too big for e-mail, consider the suggestions below.
- Compress the file - Compressing the file as a .zip or other file compression makes the file smaller in size.
- Google Drive - Google Drive, specifically Google Docs, is free and offers 5 GB of storage and allows PDF and other document files to be uploaded and shared.
- Use another online service - Many online services allow you to send and store large files.
