Download Opera 33.0.1990.43

Opera has released version 33 of its web browser of the same name. Opera switched from its in-house render engine Presto to Blink two years ago. This is part of Chromium, which is also used by Google Chrome, among others. Opera is available for Windows, Linux and OS X. There are also versions for BSD and Solaris, but they are still based on the old technology. In version 33, Opera has made improvements to Turbo, a system of compression that should make pages load faster. We have also collaborated with Google to make Blink and Chromium perform better on less powerful computers.

Opera 33 and our contribution to Chromium
With Opera 33, we want to look at another vital aspect of bringing the web to as many people as possible – making sure that the browser is performing even on slower networks and older hardware.

Compressing data for smooth internet speed
You probably know that for many years, Opera has had a Turbo mode that speeds up performance on slow networks by compressing data such as images via our servers, so they download faster. If you haven’t tried it, go to the Opera menu and select the Opera Turbo option. You won’t notice any changes to the layout or interactivity of the page, just smooth, smooth speed.

Reducing Chromium’s memory use for faster hardware performance
But, slow networks aren’t the only bottleneck you face — hardware performance matters, too. The majority of the world’s users aren’t on $1500 high-powered laptops; many people, in businesses, schools, libraries, universities and homes across the world are using older machines with less memory, older processors and slower disk drives.

So, since the release of Opera 15, our first Chromium-based browser, Opera’s engineers have been partnering with our Google counterparts to improve the performance of the rendering engine Blink. We’ve leveraged our expertise from our 15 years making our old Presto engine work well on old machines, and you can read lots of nerdy details on the mechanics of what we’ve done in our developer blog post, Opera’s work to reduce Chromium’s memory use.

Collaborating with other teams for a better web
We’ve also been contributing heavily to other ways of improving the web; for example, Blink/ Chromium’s way of showing multicolumn layouts was written by Morten from our R&D Department. Rune from R&D has done lots of work on improving the performance of styling pages so that they render faster. Sigbjørn has played a central role in the soon-shipping oil pan project to improve how Blink / Chromium cleans up memory (therefore using it more efficiently). We’re also active in Blink Chromium’s Security and Memory teams.

By collaborating with other companies on our shared code base, implementing our own user interface and features on top of that, and iterating rapidly, we’re keeping you on the fastest, most secure browser we can build, while helping to make the web better for everyone.
