A slow WordPress website can quickly turn visitors away, especially when your pages contain large APK screenshots, banners, featured images, and other media. A faster website also gives users a better experience and can help with Core Web Vitals.
If you are looking for a free way to improve WordPress speed, the combination of QUIC.cloud CDN and LiteSpeed Cache image optimization is worth trying.
In this guide, I’ll show you how to connect QUIC.cloud, configure LiteSpeed Cache, optimize your images, and check whether everything is working correctly.
The setup is beginner-friendly, and you can start without paying for a premium CDN.
Why QUIC.cloud and Image Optimization Work Well Together
Images are often one of the biggest reasons a WordPress page becomes heavy. This is especially common on APK and download websites where every app page may contain several screenshots and banners.
QUIC.cloud can help deliver website content through its CDN, while LiteSpeed Cache can optimize images and serve modern image formats such as WebP.
This can help reduce page weight and improve loading performance.
However, there is no fixed speed improvement for every website. Your results depend on your hosting, theme, plugins, image sizes, server location, and existing optimization settings.
What this setup can improve
With a properly configured setup, you may see improvements in areas such as:
- Faster image delivery
- Smaller image file sizes
- Better page loading times
- Lower bandwidth usage
- Improved mobile performance
- Better Core Web Vitals
- More efficient delivery of static content
For an image-heavy WordPress website, these improvements can make a noticeable difference.
Before You Start: What You Need
Before configuring QUIC.cloud, make sure your website meets the basic requirements.
You should have:
- A WordPress website
- A domain connected to your hosting account
- HTTPS/SSL enabled
- LiteSpeed Cache installed if your hosting environment supports LiteSpeed
- Access to your WordPress admin dashboard
- Access to your hosting control panel
If your hosting server does not use LiteSpeed or OpenLiteSpeed, some LiteSpeed Cache features may not provide the same benefits.
Step 1: Create Your QUIC.cloud Account
The first step is to create a QUIC.cloud account and connect your WordPress website.
Go to the QUIC.cloud website and create an account.
After signing in:
- Add your website domain.
- Follow the verification instructions.
- Connect your WordPress site with QUIC.cloud.
- Generate or copy the required API key if your setup asks for one.
- Keep the key available for the LiteSpeed Cache connection.
The exact dashboard options can change over time, so follow the connection instructions shown in your QUIC.cloud account.
Why the API key matters
The API connection allows LiteSpeed Cache to communicate with QUIC.cloud services. This is important for features such as image optimization and other cloud-based functions.
Step 2: Make Sure Your WordPress Site Uses HTTPS
A valid SSL certificate should be active before you configure CDN delivery.
If you use Hostinger, log in to your hPanel and look for the SSL/security section for your domain.
Depending on the current Hostinger interface, the steps may look similar to:
- Open your hosting dashboard.
- Select your website or domain.
- Open the SSL section.
- Install or activate the available SSL certificate.
- Make sure HTTPS is enabled for your website.
You should then be able to open your website using:
instead of only HTTP.
Don’t forget to check Force HTTPS
If your hosting provider offers a Force HTTPS option, enable it after confirming that your website works correctly over HTTPS.
This helps ensure visitors are redirected to the secure version of your site.
Step 3: Install and Connect LiteSpeed Cache
Now move to your WordPress dashboard.
Go to:
Plugins → Add New Plugin
Search for LiteSpeed Cache and install the official plugin.
After activating it, open the LiteSpeed Cache settings.
If your server supports LiteSpeed, the plugin can provide much more than basic caching, including image optimization and QUIC.cloud integration.
Connect LiteSpeed Cache with QUIC.cloud
Inside the LiteSpeed Cache settings, look for the QUIC.cloud connection or CDN section.
Depending on your plugin version, the exact menu names may be different.
Follow the connection process and authorize your WordPress website.
Once connected, check the dashboard for the connection status.
A successful connection means LiteSpeed Cache can communicate with QUIC.cloud services.
Step 4: Configure QUIC.cloud CDN Carefully
After connecting your account, configure the CDN settings available for your website.
Look for:
LiteSpeed Cache → CDN
Then open the QUIC.cloud CDN section if it is available in your installation.
Follow the activation instructions shown there.
Some settings and labels can change between LiteSpeed Cache versions, so don’t enable an option simply because an older tutorial recommends it. Check what each setting does before switching it on.
Check your DNS and SSL status
When the CDN is correctly configured, QUIC.cloud should show the relevant status information for your domain.
Pay particular attention to:
- DNS configuration
- CDN activation
- SSL certificate status
If one of these remains pending, give the system some time and check the DNS instructions again.
Step 5: Open LiteSpeed Image Optimization
Now we can optimize the images on your WordPress website.
Go to the image optimization section inside LiteSpeed Cache.
The available settings may vary depending on your LiteSpeed Cache version, but the main goal is simple:
Reduce image file sizes without noticeably reducing image quality.
This is particularly useful for APK websites because screenshots can quickly make a page much heavier.
Enable WebP image delivery
If WebP generation and delivery are available, enable them.
WebP images are often smaller than equivalent JPEG or PNG files, which can reduce the amount of data browsers need to download.
This can be especially helpful for:
- APK screenshots
- Featured images
- Blog images
- App banners
- UI screenshots
You should still keep appropriate original images or backups unless you are certain you no longer need them.
Step 6: Send Your First Image Optimization Request
After configuring image optimization, send the first optimization request from the LiteSpeed Cache image optimization area.
LiteSpeed Cache will process the images through the available QUIC.cloud optimization service.
Depending on the number of images on your website, processing may take some time.
You do not need to keep your computer switched on while cloud processing is taking place.
Once the request has been submitted, check the optimization status later from your WordPress dashboard.
Let automatic processing handle future images
If your LiteSpeed Cache version provides an automatic optimization or cron-based option, enabling it can reduce the need to manually submit every new image.
This is useful for websites that publish new APK pages regularly.
How to Know If Image Optimization Is Working
After sending the optimization request, open the image optimization summary in LiteSpeed Cache.
You should be able to see information about processed or optimized images.
Don’t worry if the percentage does not increase immediately. Cloud processing can take time, particularly when your website contains many images.
You can also check whether optimized image formats are being delivered to visitors.
Check an actual page
Don’t rely only on the WordPress dashboard.
Open one of your image-heavy pages in a browser and inspect the images using your browser’s developer tools or a website speed-testing service.
You want to confirm that the browser is receiving optimized image files rather than unnecessarily large originals.
Test Your WordPress Speed Before and After
Before making major performance changes, run a speed test and save the results.
After configuring QUIC.cloud and image optimization, test the same page again.
Useful tools include:
- Google PageSpeed Insights
- GTmetrix
- Chrome Lighthouse
For a fair comparison, test the same URL under similar conditions.
Focus on Core Web Vitals
Instead of chasing a perfect score, pay attention to the metrics that affect the real user experience.
Important metrics include:
- LCP (Largest Contentful Paint) — how quickly the main content becomes visible
- INP (Interaction to Next Paint) — how responsive the page feels
- CLS (Cumulative Layout Shift) — how stable the page layout remains
Image optimization can help LCP when large images are part of the main content, but LCP can also be affected by hosting speed, CSS, JavaScript, fonts, caching, and the page structure.
Why APK Websites Can Benefit From Image Optimization
APK websites often have a different performance problem from simple blogs.
An app download page may include:
- Multiple screenshots
- App icons
- Featured images
- Banners
- Related-post images
- Download buttons
- Advertising scripts
- Tracking scripts
When all of these resources are loaded at once, the page can become heavy.
Optimizing the images is therefore one useful part of a wider WordPress performance strategy.
For a site like Apkpromex, the biggest improvement may come from combining image optimization with proper caching, lightweight pages, good hosting, and fewer unnecessary scripts.
Common QUIC.cloud Setup Problems
Not every installation works perfectly on the first attempt.
Here are a few common problems to check.
CDN is not activating
Check whether your DNS records match the instructions provided by QUIC.cloud.
Also confirm that your domain is using the correct nameservers or DNS configuration required by your selected setup.
Image optimization is stuck
Give the optimization service some time before sending repeated requests.
If processing remains stuck, check the LiteSpeed Cache status and QUIC.cloud connection and make sure your WordPress installation can communicate with the service.
Website shows SSL warnings
Do not ignore SSL errors after changing CDN or DNS settings.
Check that your domain has a valid certificate and that both the WordPress URL and site URL use HTTPS.
Images still look large
Changing the image format alone does not solve every image problem.
Before uploading screenshots, resize them to a sensible display size. There is little benefit in uploading a 3000px-wide screenshot when the page only displays it at 800px.
A Few Extra Speed Improvements for WordPress
QUIC.cloud and image optimization are only part of website performance.
For better results, also review:
Use properly sized images
Don’t upload unnecessarily large screenshots.
Resize images before uploading when possible, while keeping enough quality for the visitor.
Remove unused plugins
Every unnecessary plugin can add extra code or requests.
Keep only plugins that your website actually needs.
Use page caching
LiteSpeed Cache can provide page caching features when the server environment supports them.
Make sure caching is configured correctly before judging your speed improvements.
Avoid excessive scripts
Advertising, analytics, social widgets, popups, and other third-party scripts can increase page loading time.
If your LCP remains poor after image optimization, these resources may be part of the problem.
What Results Should You Expect?
There is no universal result such as “every website becomes 2x faster.”
For example, a website with huge unoptimized screenshots may see a significant improvement after image compression. Another website with already optimized images may see only a small difference.
Your final performance depends on factors such as:
- Hosting quality
- Server location
- WordPress theme
- Plugin count
- Image sizes
- Caching
- JavaScript
- CSS
- Advertising scripts
- CDN configuration
- Mobile network conditions
The best approach is to measure your own website before and after the changes.
Final Thoughts on QUIC.cloud CDN and Image Optimization
QUIC.cloud CDN + LiteSpeed Cache image optimization can be a useful free starting point for improving the performance of a WordPress website.
For image-heavy websites, optimized images can reduce page size and make content easier to load, while CDN and caching features can improve how resources are delivered to visitors.
Just remember that website speed is not controlled by one setting. If your WordPress site still has a poor LCP after image optimization, look at your hosting, theme, JavaScript, fonts, ads, and other third-party resources as well.
Set up the basics, test your pages, and improve the areas that are actually slowing your website down. That approach is much more reliable than enabling every performance option at once.
