 1 | # PDF Nano
 2 | 
 3 | [DMG Version here][1]
 4 | 
 5 | PDF Nano could dramatically reduce the size of PDF, while keeping the images and texts clear enough for screen readers.
 6 | 
 7 | Actually, PDF Nano is an **Automator workflow**, therefore it works on **macOS only**, as a service on the context menu.
 8 | 
 9 | ## Prerequisites
10 | 
11 | You will need **Ghostscript**, a famous interpreter for the PostScript language and for PDF.
12 | 
13 | To install [Ghostscript][2], you can:
14 | *  follow [the official guide][3]
15 | *  or use [Homebrew][4]:`brew install ghostscript `
16 | *  or download and open [this install package][5]
17 | 
18 | ## Install PDF Nano
19 | 
20 | Open `PDF Nano.workflow` and install the service.
21 | 
22 | ## Usage
23 | 
24 | Right-click the PDF and select `PDF Nano` service on the context menu, and just wait for the magic.
25 | 
26 | ## Notes
27 | 
28 | * The magic may come slowly if the PDF is large. For example, it may take 40s to compress a PDF from 40MB to 2MB. Yeah, I know it’s a bit slow.
29 | * Maybe not just a bit.
30 | * File stream is not supported yet.
