A fast PrestaShop website can provide a better shopping experience, improve mobile usability, and help your SEO performance. The biggest improvements usually come from image optimization, caching, database cleanup, hosting, and reducing unnecessary modules.
1. Optimize Product Images
Large product images are one of the most common causes of slow ecommerce websites.
Use:
- WebP where supported
- JPEG for suitable photographs
- Proper image dimensions
- Image compression
- Descriptive filenames
For example:
mens-black-leather-wallet.webp
instead of:
IMG_45872.jpg
Avoid uploading a 5000px image when your website only displays it at 1000–1500px.
2. Enable PrestaShop Caching
Go to:
PrestaShop Back Office → Advanced Parameters → Performance
Check your caching and performance settings.
Caching allows frequently used content to be served faster instead of being generated repeatedly.
Depending on your PrestaShop version and hosting environment, you may also be able to use server-side caching such as:
- Redis
- Memcached
- Varnish
3. Enable CCC/Asset Optimization
In the Performance section, PrestaShop provides options related to combining, compressing, and caching CSS and JavaScript.
Where compatible with your theme and modules, enable options such as:
- Smart cache for CSS
- Smart cache for JavaScript
- Minification
- Combining files
Important: Test your entire website after changing these settings. Some themes or modules can break when files are combined or minified.
4. Remove Unnecessary Modules
Every additional module can potentially add:
- CSS
- JavaScript
- Database queries
- External requests
- Server processing
Go through:
Modules → Module Manager
Remove or disable modules that you don’t actually need.
Pay particular attention to modules that load scripts on every page, even when their functionality is only required on one page.
5. Use a Fast Hosting Server
Hosting has a major effect on PrestaShop performance.
Look for hosting with:
- SSD/NVMe storage
- Adequate RAM
- Modern CPU
- PHP OPcache
- Redis support
- HTTP/2 or HTTP/3
- CDN compatibility
- Good server response time
A heavily overloaded shared server can make an otherwise well-optimized PrestaShop store slow.
6. Use a CDN
A Content Delivery Network (CDN) can serve static resources from locations closer to your customers.
A CDN can help deliver:
- Images
- CSS
- JavaScript
- Fonts
- Other static files
This is especially useful if your customers are geographically distributed.
7. Optimize Your Database
As a PrestaShop store grows, its database can become large.
Common sources include:
- Old visitor/session data
- Statistics
- Logs
- Search indexes
- Abandoned carts
- Old connections
- Module-generated data
Before deleting database records, take a complete backup and make sure you understand what each table contains.
8. Optimize the Homepage
Your homepage often contains many elements:
- Sliders
- Banners
- Product carousels
- Categories
- Featured products
- Reviews
- Social widgets
- Tracking scripts
Remove anything that doesn’t provide real value.
A simpler homepage often loads considerably faster.
9. Reduce External Scripts
Third-party scripts can slow down your store.
Examples include:
- Facebook/Meta scripts
- Google Analytics
- Chat widgets
- WhatsApp widgets
- Advertising scripts
- Heatmaps
- Social media widgets
Review every external script and ask:
“Do I really need this on every page?”
If not, load it only where necessary or use an appropriate delayed-loading strategy.
10. Optimize Fonts
Too many font files can increase page load time.
Try to:
- Use fewer font families
- Reduce unnecessary font weights
- Prefer modern webfont formats
- Avoid loading fonts that aren’t actually used
For example, loading 8 different font weights when you only use regular and bold wastes resources.
11. Improve Core Web Vitals
Use Google’s PageSpeed Insights to check your important pages.
Pay attention to:
LCP — Largest Contentful Paint
How quickly the main content becomes visible.
INP — Interaction to Next Paint
How responsive the page is when visitors interact with it.
CLS — Cumulative Layout Shift
How much the page unexpectedly moves while loading.
Product pages and category pages should be tested separately because their performance can be very different.
12. Use Lazy Loading Correctly
Images below the initial viewport can use lazy loading.
For example:
Load immediately:
- Main product image
- Important hero image
Lazy load:
- Images further down the product page
- Related products
- Images below the fold
Don’t blindly lazy-load everything, because delaying important above-the-fold content can hurt performance.
13. Keep PrestaShop and Modules Updated
Use compatible, maintained versions of:
- PrestaShop
- PHP
- Theme
- Modules
Before upgrading a production store, create a backup and test the update on a staging environment if possible.
