11 Everything you need for a fast website. Simple set up, easy to use, awesome support. Caching, Lazy Loading, Minification, Defer CSS/JS, CDN and more!
12
13 == Description ==
14 NitroPack is the all-in-one performance optimization service. It combines **everything** you need for a lightning-fast website. Image optimization, code minification, caching, CDN, lazy loading - you name it, NitroPack has it.
15
16 [youtube https://www.youtube.com/watch?v=jLzYUKSo5Jo]
17
18 NitroPack performs all optimizations in the cloud. This makes it a **very lightweight** solution with a **lower CPU overhead** compared to standard caching plugins.
19
20 Our service provides you with the following (typically paid extra) functionalities **included without the need for additional configuration**:
21
22 * **Cloudflare CDN** – we automatically serve your static assets from a CDN based on Cloudflare
23 * **Image Optimization** – we optimize all of your images automatically and convert them to WebP
24 * **Cache Warmup** – we keep your most important pages optimized at all times
25
26 Apart from these, NitroPack offers other unique features and benefits like:
27
28 * **Incredibly Simple Setup** – getting started with NitroPack is a breeze. There’s no technical configuration or a 15-step installation process. And you don’t need to be a developer to set it up. Simply follow [these 4 steps](https://wordpress.org/plugins/nitropack/#installation "Installation Instructions") and you’ll be done in no time
29 * **No risk of damaging your original site files** – NitroPack works on copies of your site files. You don’t like the results from an optimization? No problem. Purge your cache and start over. Even if you decide to disable NitroPack your site will go back to the state it was in before activating our plugin
30 * **Cache Invalidation** – you can invalidate cache files instead of purging them. This allows NitroPack to keep serving your visitors from cache while a fresh copy of the cache is being generated in the background. Cache invalidation is awesome for **high traffic situations** like campaigns. It allows you to keep updating your site while still serving cache to your clients. And with NitroPack, **cache invalidation happens automatically**. (For more info on this, scroll down to the “NitroPack and Campaigns” section)
31 * **Critical CSS tailored to each of your unique layouts** – most plugins that provide critical CSS functionality prepare a single critical CSS file per post type. Even when you have multiple pages with the same post type but different layouts. NitroPack detects this and generates **unique critical CSS for each unique layout**. Oh, and because desktop and mobile devices have different viewports, NitroPack also uses different critical CSS for each device type ;)
32 * **Optimize resources linked statically into your theme files** – NitroPack will discover and optimize all resources linked into your theme, even ones that come hardcoded into your CSS files (even if they are multiple levels down an @import chain)
33
34 **The configuration requires no technical knowledge.** All you need to do is select your desired optimization level: Standard, Medium, Strong or Ludicrous. Besides that, NitroPack does all the work.

69 ## Running Marketing Campaigns with NitroPack
70
71 Two major issues often come up when running a campaign. First, each visitor hits your server with a **unique URL** request. Second, you lose your **cache** if you update content on your site.
72 Most optimization plugins come up short when it comes to both issues.
73 At the same time, NitroPack has two powerful features that help you thrive in these high traffic situations:
74
75 1. NitroPack recognizes **campaign parameters in the URL** and ignores them when looking up a cache file for the campaign request.
76 2. **Cache invalidation** - typically, when you update content on your site, caching plugins have to purge their cache and start rebuilding it. When a purge occurs during a high traffic period your visitors will no longer be served from cache. And your server will have to work extra hard to generate new cache files. As a result, the user experience on your website takes a hit. NitroPack solves this problem by **invalidating the cache, instead of purging it**. This method allows NitroPack to refresh the cache files in the background. At the same time, you still serve your clients from the slightly outdated cache files. As we already said, this happens **automatically**. You don’t need to worry about caching during an important campaign.
77
78 Whether you’re running a big campaign or your site suddenly becomes trending, both features are crucial for keeping your visitors happy.
79 So, if you want a fast website right now, **go over to the [Installation](https://wordpress.org/plugins/nitropack/#installation "Installation Instructions") section and download NitroPack**.
80
81 ## Incompatible Plugins
82
83 WordPress is designed to have only a single active page cache solution at a time, otherwise conflicts can arise. We do not recommend using NitroPack together with another caching plugin, like:
84
85 * WP Rocket
86 * Autoptimize
87 * Swift Performance
88 * WP Fastest Cache
89 * WP Fastest Cache Premium
90 * Powerpack (WPTouchPro)
91 * W3 Total Cache
92 * Breeze
93 * PhastPress
94 * WP Super Cache
95 * Litespeed Cache
96 * Swift Performance
97 * PageSpeed Ninja
98 * Comet Cache by WP Sharks
99 * Hummingbird
100 * SG Optimizer
101 * WP-Optimize - only the page caching must be disabled, not the entire plugin
102 * Smush - only the lazy load option must be disabled, not the entire plugin
103 * JetPack - only the lazy load option must be disabled, not the entire plugin
104 * ShortPixel - only the WebP conversion option must be disabled, not the entire plugin
105

136 == Frequently Asked Questions ==
137
138 = Does NitroPack modify site files? =
139
140 No. NitroPack works on copies of your site files. However, it does modify your wp-config.php file if WP_CACHE is not enabled yet.
141
142 = I installed NitroPack but my pages are still slow. Why? =
143
144 After installing and activating NitroPack, you must log into your account, go to “Connect Your Website” and use the provided Site ID and Site Secret to connect the plugin to our cloud service.
145
146 = Why my scores are still low after connecting NitroPack? =
147
148 After connecting NitroPack you need to select your desired optimization mode - Standard, Medium, Strong or Ludicrous. Once you do that, please visit your home page and allow NitroPack a minute to prepare an optimized version of your page. You can then run the tests again.
149
150 = How long does it take for pages to get optimized? =
151
152 It usually takes NitroPack a few seconds to optimize your pages.
153
154 = Can I use another page caching plugin and NitroPack at the same time? =
155
156 WordPress’s design allows you to use only one page cache solution at a time. Other page cache solutions are designed this way too. However, you can use other non-page cache optimization solutions perfectly well with NitroPack.io (e.g. database optimization plugins, object caching, etc.).
157
158 = What if I have a question? =
159
160 You can contact us anytime at https://m.me/getnitropack
161
162 = Will NitroPack slow down my server? =
163
164 No. We’ve designed NitroPack to be a very lightweight solution that adds no CPU overhead to your server.
