Although the connections to the Opera Servers are encrypted when visiting a secure web page, the compression technology has to access the version of the web page that is unencrypted so there is no strict end-to-end encryption between the client and remote server. Opera Mini has perceived security risks with the their compression services decrypting web pages remotely. Opera replaced its engine with Chromium – the same engine used by Chrome, and by doing this, the Opera browser made leaps and bounds in its security, becoming the preferred browser over Opera Mini with secure site browsing. The Opera browser has one up on Opera Mini when it comes to security. Opera Turbo can be enabled in the Opera browser as a service offering high compression where Opera Mini provides extreme compression. The Opera browser compression is based on the device’s accessible network performance and does not compress the web pages by default, whereas Opera Mini sends requests to their servers that download and compress the web page before sending it back to the device browser, thus providing increased performance.

Opera Mini’s compression makes it lighter compared to the standard Opera browser. This is how Opera Mini copes so well in network areas that suffer intermittent internet access, congestion, and high mobile data rates. The servers perform up to 10% compression of the original size of all images and text in the web pages. The biggest difference between Opera and Opera Mini is how the web pages are compressed.īeing a cloud-based browser, Opera Mini requires minimal storage on a device as all browsing moves through the Opera servers. The Opera browser app is more popular in countries with high data availability, such as the USA and Japan, whereas the Opera Mini browser is widely-used in places with more inferior network infrastructures like India. The Opera Mini app consumes less resources at a lower rate, which is less than a quarter of data compared to the Opera browser when actively in use.

The Opera browser app has been available on the Google Play Store since 2012, and in 2014, Opera launched the Opera Mini app geared towards low-powered devices available to most phone manufacturers.Īnalyzed by M2 Mobile Insights, Opera Mini’s background resource consumption and impact on performance on low-powered devices, measured significantly less than the Opera browser on Android. Opera is a web browser that runs on Windows, Linux, and Mac desktops, and as a mobile app for Android, whereas the Opera Mini browser is only a mobile app compatible with most phones, such as Windows, Android, and iOS.
