Your PDF fonts are just as equally important as your images. Take advantage of this feature if you have it. In most cases, you can choose to automatically subset fonts if the character usage is less than a certain amount. If a special character like “#” isn’t used in the file, the character won’t be included. When you subset a font, you attach only the font characters that are used in the PDF. Subset Your Fontsīy embedding fonts, you are essentially attaching the entire character set within the PDF, which can puff up the file significantly. And one less data channel means a smaller file size. In some PDF creators, you can choose to convert CMYK images to RGB if needed. If your PDF is mainly going to be viewed on the web or on a computer screen, choose the RGB colour space for your PDF images. In general, CMYK is ideal for print purposes, while RGB caters to on screen viewing. Each one has different methods of handling colour. You may have heard of RGB and CMYK colour spaces before. As well, you can usually set the desired resolutions and decide if you want to compress your images using popular compression algorithms such as ZIP, LZW, or JPEG. Each has its own advantages, so choose wisely. You’ll be able to choose mainly between bicubic, subsample, and average downsampling methods. When you downsample bitmap images you basically decrease the amount of pixels in it which reduces the overall resolution and hence, the size of the PDF.ĭownsampling options will tell your PDF program know how you want to delete those pixels. However, if your PDF isn’t intended for high resolution needs, you can keep your file under control by downsampling and compressing your images. Given the visual nature of digital content today, images are a big part of PDF files. So go for the “Save As” option once you’ve added everything you need to your PDF. The result is a smaller PDF file you can manage. By doing this, you overwrite the entire file, eliminating unused objects and accumulated changes. This is because the function saves the changes and appends them to the file. Every time you hit Save in an application, you end up with a usually bigger file size. This is a good place to start to cutting down the bloat. Some fine-tuning here and there will go a long way to shave the megabytes off of your file. How can you slim down the size of your PDF document? While this heavily depends from PDF to PDF and the type of content it contains, there are a few general PDF creation options in particular which you should pay close attention to.

There’s nothing worse than an email stuck in your outbox because of a large PDF attachment-unless, of course, it’s a slow PDF download from the web. One of the biggest pet peeves of dealing with a PDF file is the large file size.
