skyZIP browser extension is perfect for anonymous internet access like a VPN service and can do even more and faster.

skyZIP can reduce data usage by using high performance proxy servers to optimize webpages. Data savings are at about 50%

Many web-sites are not optimized – but skyZIP is transcoding images to WebP lossless format, resulting images are 80% smaller.

Content compression – deleteting of unnecessairy information in HTML, Javascript and CSS resources which are not essential combined with gzip compression is resulting in bandwdith savings for the users and operator.

The use of an optimized protocol which is also the basis for HTTP/2.0 is in use between your browser and the Proxy server farm. Multiplexing multiple request and response streams in parallel over a single TCP connection which is reducing TCP handshake overhead for multible requests, higher throughput by removing TCP slow-start phase – increase of loading speed of webpages on already TCP accelerated environments is about 100% on non TCP accelerated systems up to 1000%

Secure connections (HTTPS) are routed from your browser to the destination by saving one roundtrip per DNS request. DNS lookups are performed by Proxy Servers, no need for the Browser to wait for responses. – this is also reducing cpu load on the modem.

Harmful webpages are blocked automatically in our Datacenter – will safe bandwidth, increase speed, will keep your computer away from phising web-sites
