Quetta is a mobile browser for Android and iOS designed to make watching, saving and managing online video more convenient. Its built-in downloader can save compatible MP4 and WebM files, as well as supported M3U8 and HLS streams, when media is available on a webpage. Availability depends on the source, website, access controls and app version. An enhanced video player offers features such as picture-in-picture, background audio, playback speed controls, captions and casting, depending on the video and device.

The browser also includes ad and tracker blocking to reduce supported pop-ups, intrusive page elements and tracking requests. Privacy controls let users manage browsing data and site permissions, while protection varies with settings and website behavior. On Android, Quetta supports many browser extensions from the Chrome Web Store and Microsoft Edge Add-ons. Users can install, enable, disable or remove extensions, though compatibility may vary, particularly for tools designed for desktop use. By bringing video tools, browsing protections and customization together, Quetta serves people seeking a more flexible mobile browsing experience.
