How to Move from NitroPack to FastPixel (The Easy Way)

Most people avoid changing performance plugins because caching setups can be fragile.

One wrong setting can affect layouts, scripts, or PageSpeed scores, so the plugin that works “well enough” often stays in place longer than planned.

Moving from NitroPack to FastPixel is much simpler.

There’s nothing to export, no configuration to rebuild, and no migration wizard to run. You disconnect NitroPack, activate FastPixel, pick a preset, and FastPixel starts handling the optimization automatically.

This guide walks through the full process: why people switch, how to move safely, and what to check once FastPixel is running.

Why people consider the switch

NitroPack is a good performance service, and plenty of sites run happily on it. If yours is fast and your Core Web Vitals are good enough, there may be no pressing reason to change anything, unless you want better speed and better scores.

The conversation usually starts around two things: cost as traffic grows, and a preference for a setup that lives entirely inside WordPress with less to manage over time.

NitroPack is a SaaS product priced by pageviews. Its free tier covers 1,000 pageviews a month and 1GB of CDN traffic, paid tiers scale up from there as traffic increases. That structure suits a lot of sites well. For others, particularly anyone juggling several sites or watching traffic climb, the pageview math is what nudges them to compare options.

FastPixel takes a different shape. Image optimization (powered by ShortPixel), CDN delivery, Critical CSS, font handling, and page caching all live in one plugin, available on every plan including the free one. The optimization features don’t sit behind higher tiers; paid plans mainly raise the pageview ceiling.

Both tools do their processing in the cloud, so the real distinction isn’t where the work runs. It comes down to pricing model and how hands-on each one is once it’s set up.

For what it’s worth on results: FastPixel has the best real-world Core Web Vitals numbers in the HTTP Archive Technology Report, which tracks the share of origins passing LCP, INP, and CLS across different technologies. Worth a look if you like to see data before deciding.

Before you start

A couple of minutes of prep removes the only friction you’re likely to hit.

Note down any custom exclusions. If you’ve told NitroPack to leave certain URLs, scripts, or stylesheets alone, save that list somewhere. FastPixel handles most exclusion scenarios on its own, so you’ll probably never reach for it, but it’s handy to have if a specific element needs attention later.

Record your current scores. Run the site through PageSpeed Insights and note where you stand. That’s your baseline for judging the before-and-after once FastPixel is live.

Nothing else to do. No export, no import file, no compatibility audit.

The actual migration

Five steps, and you’ll likely be through them in under five minutes.

Step 1: Disconnect NitroPack from your site

Open NitroPack > Settings in your WordPress admin and disconnect the site from the NitroPack service first. This closes the connection neatly and clears NitroPack’s cached copies from their CDN.

Deactivating the plugin would trigger the disconnect anyway, but doing it on purpose from the dashboard keeps things tidy and avoids leaving a stray site sitting in your NitroPack account.

Step 2: Deactivate NitroPack

Head to Plugins > Installed Plugins, locate NitroPack, and hit Deactivate.

Hold off on deleting it for now. Leaving it dormant for a day or two means you can flip back instantly if you want to compare something while FastPixel settles in.

Step 3: Install and activate FastPixel

Under Plugins > Add New, search for FastPixel, install it, and activate.

It’ll ask you to link a FastPixel account. The free plan includes the whole optimization stack within its limits: CDN, image optimization, Critical CSS, and page caching. You can finish the entire migration on the free plan if you want to.

Paid plans exist for sites with higher traffic, but the optimization features themselves are there from the free tier up.

Step 4: Pick a preset

There are three to choose from: Safe, Balanced, and Fast.

Fast is the one most people want for Core Web Vitals. Select it, and FastPixel sets the key optimization options for you, tuned for strong performance. No tab-by-tab fiddling required.

Step 5: Let FastPixel optimize your pages

Your main pages go straight into the optimization queue. The rest get processed as visitors land on them, so the first hit on an unoptimized page may kick off the work, and everyone after that gets the finished version right away.

What you get without extra setup

The nice part after switching is that the whole stack is already in the plugin, no companion services to wire up:

• Page caching via FastPixel’s cloud
• Critical CSS built per page and refreshed when content changes
• CSS and JavaScript optimization, with minification and deferral
• Image optimization through ShortPixel’s cloud, including WebP conversion and delivery
• LCP image preloading so your above-the-fold image loads first
• Font optimization, font-display handling included
• CDN delivery covering HTML, CSS, JS, images, and fonts

Running Redis or Memcached on your host? FastPixel can use Object Cache too, which helps on busier dynamic sites like WooCommerce shops or membership platforms.

Once you’ve switched

Confirm the green Cached status for your pages in the FastPixel dashboard.

Run PageSpeed Insights again and set it next to your baseline. You want to see LCP improve, CLS hold steady or get better, and the list of “opportunities” shrink.

Eyeball a few important pages. Homepage, a post, your key landing page, and a checkout or contact page if you have one. A quick visual pass is enough to confirm everything looks right.

Glance at the dashboard. It lists what’s been optimized and flags anything that needs a second look, so if a particular page isn’t behaving as expected, that’s where you’ll spot it.

Day-to-day after the move

There isn’t much to it.

FastPixel runs on its own. New posts get optimized as you publish them. Edit a page and the cache clears and rebuilds without any input from you. There’s simply less to keep an eye on, and not much manual tuning once it’s set up.

That last part tends to be the real win for people. Faster Core Web Vitals are great, but not having to think about your performance plugin week to week is often what makes the switch stick.

FAQs

Can I run NitroPack and FastPixel together?

No. Two optimization services working at once will clash, process your assets twice, and usually land you with worse results than either alone. Disconnect and deactivate NitroPack before turning on FastPixel. To try FastPixel risk-free first, spin it up on a staging site.

Will my NitroPack settings carry over?

No, and you won’t need them to. The two tools are configured in completely different ways. NitroPack ties its optimizations to its own pipeline; FastPixel leans on presets meant to cover what most sites need without manual adjustment. That hands-off approach is a big part of why people switch.

Does FastPixel handle image optimization too?

Yes. Image optimization comes built in through ShortPixel, with WebP conversion and CDN delivery included, so there’s no separate image service to keep around after you switch. It’s handled automatically as part of FastPixel’s setup, with fewer separate tools and settings to manage.
