We've compiled the best tools to shrink a PDF file and make it smaller into 4 general categories.
1. Adobe Acrobat Pro
If y'all accept Adobe Acrobat installed on your computer, there's a tool within the application called "PDF Optimizer". This is one of the best and easiest ways to shrink a PDF document.
To get to this, open your PDF in Acrobat, click Tools > Optimize PDF. A toolbar with a few options will announced but above the PDF.
If you click Reduce File Size, y'all can choose to reduce a single or multiple files. Next, you lot'll choose the file location and name. Once y'all click Relieve, Acrobat will apply default settings to your file to endeavor to reduce its size.
If you click Advanced Optimization, yous'll have more options to ensure you maintain the quality you demand. To help with this, in the Advanced Optimization window, click Inspect Infinite Usage, and you'll exist able to run across how much infinite each kind of element is taking up within the file.
Using default setting, our sample file shrunk from 11,775KB to only 212KB, making Adobe Acrobat Pro one of the most effective PDF compressor in this list. It's a paid tool, after all, but at that place was one free tool that performed better with default settings. Adobe Acrobat Pro DC will fix you lot back $14.99 per month, merely you can go a 7-day free trial.
NeeviaPDF
If you lot desire more than command over the quality of your compressed PDF, try DocuPub's NeeviaPDF (for files less than 24 MB in size).
To go along things simple, you can choose one of the presets, which range from low compression (for a higher image quality) to maximum compression (for a lower paradigm quality). You're besides given the option to discard certain elements from within your PDF. This includes things like forms, annotations, and page labels, which tin unnecessarily increase the size of the file.
Our sample PDF lost 98% of its size, clocking in at only 203KB, down from 11,775KB. This was the smallest we achieved in our tests, and the consequence looked just fine. How much of the original PDF you want to discard depends on how much space you actually need to save.
Windows 10 finally includes an choice to print-to-PDF. However, advanced features, like tweaking the quality and size of a document, are not part of this characteristic. Meanwhile, many PDF printers permit you choose quality and compression settings, which can greatly influence the size of your PDF files.
Notation that the tools highlighted beneath crave GhostScript to view and handle PDFs.
FreePDF
FreePDF is a classic PDF printer, and we highlight information technology hither considering it allows y'all to create your ain compression profiles. Once installed (remember that yous need GhostScript), yous'll find it listed every bit function of your Windows printers.
To reduce the size of a PDF document with FreePDF, open up it, printing Ctrl + P to launch the impress dialog, choose FreePDF equally your printer, click OK, and await for the FreePDF dialog to pop up. Here, y'all tin choose from three preset PDF profiles, including eBook, High Quality, and Medium Quality.

You can change the full general quality of your PDF, adapt the default resolution for pictures within a PDF, or add together a watermark to your PDFs.
The default medium quality profile compressed a scanned PDF document of 10 MB to a i.vii MB PDF file with an acceptable loss in quality.

Once you've selected which files you desire to shrink (elevate and drop is supported), select the location where you desire the smaller files to be saved. You tin can overwrite the former file or save a copy. Hit Compress and the tool will do all the work for you. Our five sample PDFs took a few minutes to compress and came out eleven.5MB or 29.five% smaller.

This completely free slice of software is also extremely simple to use. Select the file y'all want to compress, striking Compress, and so salvage the smaller file.
In addition, you can choose from 5 levels of compression, depending on how y'all want to apply the file:
- Low resolution (72 dpi), ideal for screen-view only
- Medium resolution (150 dpi), ideal for an ebook
- Loftier resolution (300 dpi), platonic for press
- Prepress (300 dpi), platonic for prepress, including color preserving
- Default, ideal for a broad variety of uses
Our single sample file was done in less than a minute and, due to choosing the maximum pinch level, came out at only 276KB, down from 11,775KB. The final image quality was perfectly fine.
IrfanView
IrfanView is a lightweight and feature-rich image viewer for Windows. It comes with a range of plugins that turn it into a versatile image editing tool, for example, to catechumen images to different file types, add together watermarks to your photos, and batch process images.

PDF Filter
If you routinely update your Mac's operating arrangement, you should be able to shrink your PDF without installing any new apps. This is a cool feature in OS X that many people don't know most.
Offset, open your PDF in preview. Commonly you tin can just double-click the file, but if you lot have a PDF reader such as Adobe Reader installed, y'all'll want to correct-click > Open up With > Preview). And so click File >Export, and in the Quartz Filter drib-down box, select Reduce File Size.
This just works with large PDF files. Try doing this with a very small PDF (less than a few MB), and these could actually increase in size.
