Gzip Compression Wix

1. With some compression methods the last byte or code can be interpreted as more data if you try to read more data than was present when compressing, due to leftover bits, but I'm not sure this holds for gzip.
2. In recent times, GZIP Compression has become the de-facto standard for many sites to upload compressed versions of files on web hosting servers. It was developed for the ease of website.
3. Is this a bug report, a suggestion or feedback? Bug Report Suggestion Feedback: If this is a bug report, please provide full details of how to duplicate the problem you had (including any URL's or other.
4. Website gzip compression makes it possible to reduce the file size of a web file (like HTML, PHP, CSS and Javascript files) to about 30% or less of its original size before these files get sent to the browser.

Enable text compression

Text-based resources should be served with compression to minimize total network bytes. The Opportunities section of your Lighthouse report lists all text-based resources that aren't compressed:

I used to build installs for an app with NSIS and the final self extractor was 1.2 MB. Now I need to use WIX due to operational needs and the same install comes out at 4.2 MB. I set the compressed flags as the.

How Lighthouse handles text compression #

Lighthouse gathers all responses that:

• Have text-based resource types.
• Do not include a content-encoding header set to br, gzip, or deflate.

Lighthouse then compresses each of these with GZIP to compute the potential savings.

If the original size of a response is less than 1.4KiB, or if the potential compression savings is less than 10% of the original size, then Lighthouse does not flag that response in the results.

The potential savings that Lighthouse lists are the potential savings when the response is encoded with GZIP. If Brotli is used, even more savings are possible.

How to enable text compression on your server #

Enable text compression on the server(s) that served these responses in order to pass this audit.

When a browser requests a resource, it will use the Accept-Encoding HTTP request header to indicate what compression algorithms it supports.

If the browser supports Brotli (br) you should use Brotli because it can reduce the file size of the resources more than the other compression algorithms. Search for how to enable Brotli compression in <X>, where <X> is the name of your server. As of June 2020 Brotli is supported in all major browsers except Internet Explorer, desktop Safari, and Safari on iOS. See Browser compatibility for updates.

Use GZIP as a fallback to Brotli. GZIP is supported in all major browsers, but is less efficient than Brotli. See Server Configs for examples.

Your server should return the Content-Encoding HTTP response header to indicate what compression algorithm it used.

Check if a response was compressed in Chrome DevTools #

To check if a server compressed a response:

1. Press Control+Shift+J (or Command+Option+J on Mac) to open DevTools.
2. Click the Network tab.
3. Click the request that caused the response you're interested in.
4. Click the Headers tab.
5. Check the content-encoding header in the Response Headers section.

Gzip Compression Tool

To compare the compressed and de-compressed sizes of a response:

1. Press Control+Shift+J (or Command+Option+J on Mac) to open DevTools.
2. Click the Network tab.
3. Enable large request rows. See Use large request rows.
4. Look at the Size column for the response you're interested in. The top value is the compressed size. The bottom value is the de-compressed size.
