PhastPress has the Phast web page optimisation engine by Albert Peschar and Milko Kosturkov at its core.

- Phast inlines small images (< 512 bytes) in the page.
- Phast converts JPEG images into WebP for supporting browsers.
- Phast enables native lazy loading to speed up page loading and save bandwidth.

Almost great
by sgpro·1 year ago
Solid plugin, but if it could allow the exclusion of certain JavaScript assets, then I’d rate this a 5 stars
Best page speed optimization plugin for static assets
by iontulburedev·2 years ago
Best page speed optimization plugin for static assets if you don’t have a LightSpeed Server. If you run on Nginx/Apache then install this plugin and you will have better page speed.
Amazing plug-in in combo with WP Meteor!
by Toine Rademacher·3 years ago
I once saw a video from a YouTuber called Web Squadron. He adviced to use Phastpress and WP Meteor to use to optimize WordPress. I’ve been using WP Rocket for a while now. It did improve the speed of our site but all those options were just too hard to perfectly set up.
Phastpress is just a really simple and a great plug-in. It improves the Pagespeed score a good bit and in combination with WP Meteor, it’s even better! I myself use EWWW Image optimizer to optimize and lazyload all my images. I can easily disable the lazy load option in Phastpress and it seems to be perfectly compatible with all sort of plugins. It works great with Elementor (and WooCommerce, ARMember, ACF, etc) and I haven’t seen any quirks yet.
Thank you for creating this great FREE plug-in!
Fast, Simple, Accurate and great Service
by johns1951·3 years ago
This plugin is simple to setup but it very effective in optimizing the website. The number of requests for a page when way down. Initially there were some errors caused by CSS Optimizations. Albert quickly responded within a few hours, even over the weekend, and changed a setting to fix the problem. I was made of aware of this plugin by Imran “How to Boost Page Speed Optimization WordPress for FREE in 2023 ”
Best Optimization Pluigin
by jake79·3 years ago
Over the years, I think I’ve tried just about every optimization plugin out there, Including WP Rocket, Autoptimize, etc.
PhastPress is better than all of them, and it’s free. I’d be happy to pay for this plugin; it’s that good.
Big thanks to Albert :))
