Customer Testimonials

It works like expected, easy to install, and to use, works very well, and good support. Install and enable plugin and all works like a charm, if you need to disable gif webp conversion you can do it in plugin configuration. Save your time and buy this extension :-), in other websites I did it manually and spent a lot of time, now with this extension it's much faster. I used it to optimize website performance, reduce latency, and optimize Google Page Speed.
Jordi Catà Joomla Extension Directory
Dette plugin er præcis hvad jeg ledte efter til mit fotografi-websted. Installationen var utrolig nem, og jeg kunne straks se forbedringen i indlæsningstiden på min side. Billedkvaliteten forbliver fremragende, men filstørrelserne er betydeligt reduceret. Jeg havde et spørgsmål om konfigurationen, og supportteamet svarede inden for få timer. Jeg kan især godt lide muligheden for at ekskludere bestemte mapper fra konverteringen. Et must-have for enhver Joomla-side med mange billeder!
Anders Johansen JoomlaX

Excellent plugin support via tickets (WebP Converter page) that quickly helps and fixes any problem (I speak from my own experience).

Ho installato questa estensione sul mio sito di portfolio fotografico e i risultati sono stati immediati. Le immagini si caricano molto più velocemente mantenendo un'ottima qualità visiva. L'installazione è stata semplicissima e non ha richiesto alcuna configurazione particolare. Ho apprezzato particolarmente la possibilità di escludere determinate cartelle dalla conversione. Il supporto tecnico ha risposto rapidamente quando ho avuto bisogno di assistenza. Un investimento che consiglio vivamente a chi ha un sito con molte immagini!

Diese Erweiterung hat die Ladezeit meiner Joomla-Website erheblich verbessert. Die Installation war kinderleicht und die Einrichtung intuitiv. Besonders beeindruckt hat mich, wie nahtlos die Konvertierung im Hintergrund funktioniert - keine manuellen Schritte erforderlich. Der Support reagierte schnell auf meine Frage zur Kompatibilität mit meinem Cache-Plugin. Mein Google PageSpeed-Score ist von 72 auf 89 gestiegen, was die Investition mehr als rechtfertigt. Sehr empfehlenswert für jede Joomla-Website!

This extension has dramatically improved my e-commerce site's performance. Installation was straightforward and required no complex configuration.
