Shrink PDFs and Other Files
for Faster Page Loads & Bandwidth Savings

Serve content up to 50 times faster

Reduce File Size

Reducing file size is the best way to speed your Web content. HTTP compression allows content to be served up to 50 times faster while reducing bandwidth costs.

Content Compression & Decompression

Web content compressed to as little as 2% of original size with flawless decompression ensured by real-time browser compatibility checking.

HTML Optimization

Advanced HTML and CSS code optimization further improves performance and combats hackers' source sifting.

Result

Faster page loads, reduced bandwidth costs, and Web servers that can handle more throughput.

Port80 Software's httpZip is a IIS server module for ISAPI-based compression on IIS 4, 5, and 6.0 Web servers.

IIS 4: There is no native compression tool on IIS 4, so httpZip is the perfect solution for a Windows NT performance boost.

IIS 5: httpZip replaces the flawed ISAPI compression option, overcoming known browser incompatibilities and configuration bugs.

IIS 6.0 on Windows Server 2003: A robust compression engine is built into the Web server, but suffers from a fatal flaw – it lacks browser compatibility checking.

To simply upgrade the native IIS 6.0 compression, enabling browser checking as well as consolidated configuration options, use our ZipEnable tool.

HTTP and HTTPS (SSL) compression for Microsoft IIS Web servers

httpZip provides compression for any type of Web server response through the application of GZip or Deflate compression encoding.

Static Compression

Common static compression candidates include: HTML, CSS, JavaScript, XML, Microsoft Office documents, text files (or any type you like).

Dynamic Compression

Common dynamic candidates include: ASP, ASP.NET (including the ASP.NET AJAX framework), ColdFusion, PHP, Perl, JSP (or any type you like).

Image Compression

httpZip supports image compression candidates such as: PDF, PNG and Bitmap files (or any type you like).

30 - 60% Average Reduction
in File Size

A 30-60% average file size reduction (2.5 times faster) and as high as 98% reduction (50 times faster) in file size.

Optional Extra Compression

httpZip allows for more than 10% extra compression with optional HTML and CSS code optimization.

Bandwidth Utilization

httpZip decreases bandwidth utilization by up to 60% while boosting user capacity by as much as 20%.

Optimized Request Handling

Better CPU and memory utilization to make the most efficient use of Web server resources for improved throughput and stability.

Granular Compression Control

Global or by-site compression with fully customizable rules, overrides, and exclusions by MIME type, browser, file extension, file size, directory, file name, HTTP 1.0 user agent, and HTTP 1.1 proxies.

Streaming & Chunked Transfer Encoding

Reliably compress streamed and chunked responses for faster Time to First Byte and perceived page load time (buffer/no-buffer control).

Debug Mode

Debug mode available for troubleshooting during evaluation or on production systems with diagnostic reports (contact Support to activate this feature).

ISAPI Compatibility

Implemented as super-fast ISAPI filter including Ajax compression optimization.

Simple User Interface

Compression easy to deploy and manage with a GUI, tab-based Settings Manager accessible via the Start menu and a COM interface for programmatic control of basic compression settings. Also, Web-based reporting with in-memory logging for fast, secure, and accurate tracking of compression and bandwidth savings by site. Restrict browsing to Web-based httpZip reports by IP address to avoid unauthorized access.

Akamai Content Distribution Network (CDN)

httpZip supports the Akamai Content Distribution Network (CDN) including compatibility with the Akamaizer DLL.

Improved Third Party Integration

httpZip's third party integration extended to cover various versions of Windows SharePoint (SPS, etc.), Microsoft's Internet Security and Acceleration Server (ISA) running as a gateway to compressed origin servers, Microsoft Small Business Server with IIS embedded, Exchange 2000 with Outlook Web Access (OWA), BEA WebLogic application servers, IBM WebSphere application servers, Tomcat application servers, and numerous third-party ISAPI filters, including URL rewriters.

Import/Export

Import/export settings system to help support settings in Web farms and complex networks.

Compression Defaults

Smart compression defaults for safe and high speed compression right out of the box. Default compression settings, especially for hosting providers: Set httpZip defaults automatically for new Web sites.

Deflate-only Compression Option

httpZip provides a choice over which compression algorithm to be applied to content.

Real-time Browser Compatibility Check

httpZip avoids known decompression bugs on all major browsers -- also supports decompression on client systems running Symantec's Norton Internet Security.

Built-in Compression Cache

httpZip bypasses needless recompression for better CPU performance (not installed by default). In-memory compressed content cache for faster access. Cache even compressed dynamic content for database-driven pages with either unique query string or cookie values. Exclude certain content from compression cache. Compressed streamed and chunked data is cacheable. Compatible with the IIS 6 kernel-mode cache on Windows Server 2003.

Ease of Use

Simple to install/uninstall and configuration settings can be modified without restarting/interrupting IIS Web server.
