Here’s a tip for fine-tuning the downsampling function: Set both fields to the same value, so that all image content is downsampled to the lowest resolution. So what happens to an image that is 149 ppi? It remains at 149 ppi. Notice that the Downsampling control offers a threshold-the default options for Smallest File Size downsamples to 100 ppi any images that are over 150 ppi. The rectangular artifacts in the two Smallest File Size examples are typical of harsh JPEG compression. Here, you can compare the results of the Press Quality setting, Smallest File Size with the default options, and Smallest File Size, minimum quality. For image content such as an out-of-focus background shot, it’s fine to downsample and compress more aggressively. How do you determine the correct settings? It’s a bit of a juggling act if you want to retain more detail in important images, you’ll have to accept a bigger file size. The more aggressive your choices, the smaller the resulting file will be.

This looks complicated, but it’s just the same question asked three times: how to downsample and compress image content.ĭownsampling discards pixels and, as you might expect, results in a loss of both file size and detail. Compression uses color averaging methods to reduce the complexity (and thus the size) of image content. Select Compression to view the compression and downsampling options. Someone viewing the PDF in a web browser can read the first page while remaining pages are being downloaded as a background process.īy the way, I’m using InDesign CC 2015, which includes options for the initial view of a PDF it’s nice that you can now do this in InDesign, without having to polish it off in Acrobat. In the General tab, take note of the option to Optimize for Fast Web View: This doesn’t reduce file size (it actually adds a bit), but it allows page-at-a-time serving of the PDF. Choose a location for the file and type a name, then explore the PDF creation options. If you’re creating a PDF to be posted online, or sent as an email attachment, select the obvious option: Smallest File Size. So how can you squish pixels?Ĭhoose File > Adobe PDF Presets. If it also contains vector content (such as logos, diagrams, or maps), it still consists of fairly compact content. If your document consists solely of text, there’s nothing to compress.
Adobe InDesign and Illustrator provide granular options for controlling the resolution and compression of image content. What makes PDFs large? The primary villain is the pixel, so that’s where you must squeeze. Here are a few ways to make your PDFs smaller from the get-go.
And there are third-party utilities that may be able to further reduce the size of a document.īut your best shot is to address the problem when you’re creating the PDF in the first place.

Acrobat Pro DC offers some tools for reducing file size. You can use a file transfer service, such as or. We’ve all been there: You want to attach a PDF to an email, but the file is too large to send-the recipient’s service provider won’t accept it.
