Source Code Tools

CSS Validator
Validate your stylesheets with our CSS Validator Tool. What is CSS? CSS stands for Cascading Style Sheets. CSS is a descriptive style sheet language that provides the layout and presentation for markup languages like HTML & XHTML. CSS is a major part of rendering websites as we see them in our browser - it can customize the look & feel of a website completely, and is relied on more and more for presentation than deprecated HTML tags and attributes that control the look & feel of elements. What is CSS Validation? Cascading Style Sheets follow a specific format for how they should be properly structured. If a style sheet is not properly formatted, it might still work in some browsers and not be totally obvious (most browsers do their best to render whatever is thrown at them), but having errors in the CSS for a website can lead to weird display issues or outright failure. Validation of CSS checks the format and structure of a CSS file against the W3C standards to determine if it's properly formed or not. This is a good test to make sure CSS is structured well and won't cause problems for users. How Does the CSS Validator Work? Just enter the URL of a CSS file to check, and our CSS validator will validate the style sheet directly with W3C.

Domain Whois Retriever
Check Whois details for any domain name with the Domain Whois Retriever Tool! What is Whois Information? WHOIS is an information storage, retrieval and request protocol. The WHOIS protocol is defined in RFC 3912, and provides the framework for the domain name whois system that stores and provides information on domain name owners. Whois information for domain names typically stores the full names, addresses, phone numbers, email addresses, and other details for individuals and organizations responsible for the management, administration and handling of different aspects of a domain name. Typically, a domain name has a Registrant record, an Administrative Record, and a Billing record at minimum. However, Whois data isn't always completely accurate, up-to-date, or in some cases is completely blocked by privacy guards. It's common for a website or domain name owner to provide the name of an organization and generic contact information, or to use privacy guards that block most of the whois information from public view. Whois records also will provide the nameservers in use for a domain name, which is typically an important part of fetching Whois info for webmasters. What Can I Use the Whois Retriever Tool For? The whois tool can be used to check your own domains to determine how accurate and up-to-date your Whois information is, and also to determine how your nameservers are configured. You may also use the Whois tool to check someone else's domain name and learn more about who is running the website and where the nameservers are hosted, including some details about the Web hosting company.

HTML Encrypter
Encrypt your HTML source code to hide it from prying eyes! Our HTML Encrypter Tool will accept your full HTML source code, and return a fully encrypted version of the code that makes it virtually impossible to read or copy. If you're worried about someone stealing your HTML code or snooping around in your source, the encrypted HTML will make their job much more difficult. How Does HTML Encryption Work? HTML encryption works by converting common characters into character code entities, that are then converted back into normal characters by a visitor's browser. While the encrypted version can be decrypted by a decent programmer, it makes it virtually impossible for your average user to read. How Do I Use the HTML Encrypter? In order to encrypt your HTML code, you must copy + paste the code you wish to encrypt into the box below. If you are trying to encrypt your entire web page, copy the full source code of your website files. However, since most websites are dynamic and don't use HTML restricted to a single file, you will probably be copying the HTML for a single page's contents. If possible, try to use as little HTML as possible - if you're trying to hide a small chunk of your source code, don't bother encrypting the entire page to hide that one small piece. Once encryption is complete, copy + paste the encrypted version provided by this tool back to your website or CMS. It will look very strange, but your browser will render and format it properly.

HTML Markup Validator
Validate your HTML code with the W3C using our HTML Markup Validator Tool. What is HTML Markup Validation? The Hypertext Markup Language (HTML) follows a specification (actually, several specifications depending on the DOCTYPE of the HTML). These specifications, or "recommendations" are provided by the World Wide Web Consortium (the W3C). The W3C is an international standards organization that maintains the standards for the HTML markup language. This includes all the tags, elements, formatting, and structure of how HTML should be written. Validating HTML means checking your HTML source code with the W3C against the specifications to determine if it properly formatted and whether it contains any serious errors or warnings. The W3C provides validation on their site, and our tool quickly cross-checks the URL you provide with the W3C for a full standards-compliant validation of your source code. Why Should I Validate My HTML Source Code? It's true that many Web browsers will render a web page just fine even when it contains significant HTML errors. Browsers make their best attempt to render whatever they encounter, but having errors in your HTML source code can end up causing problems for your visitors that you might not even know about. Ensuring that your code is valid and follows the appropriate recommendations for your DOCTYPE is a very good idea for a standards-compliant website.

HTML Optimizer
Optimize your HTML code with the HTML Optimizer Tool. Reduce the length of your HTML and improve readability by running your source code through the HTML Optimizer Tool. What Does the HTML Optimizer Do? The HTML optimizer lets you copy + paste your source code into the tool form below. The HTML optimizer then scans your source code and removes as many unnecessary linebreaks, newlines and spaces as possible. Removing all these extra newlines and spacing doesn't change how your HTML code works on your website. It should still render perfectly find when viewed in your Web browser, but the source code itself takes up less space on the Web server, takes less time to be sent to the visitor, and reduces the overall "bloat" of your site. What Can Be Optimized With This Tool? The HTML Optimizer is designed for cleaning up HTML source code, but you can also use it to optimize your CSS code, JavaScripts, or just about any plain text file such as a keyword list. If you have a large list of websites, keywords, or a plaintext document with tons of extra space in it, the HTML Optimizer will clean it up as well.

MD5 Encrypter
Encrypt text with MD5 encryption using the free MD5 Encrypter Tool. What is MD5 Encryption? An encryption algorithm is designed to obfuscate, or encrypt, one piece of information into an unreadable format. The MD5 Message-Digest Algorithm is a 128-bit cryptographic hash function. An MD5 hash is an encrypted text that is usually a 32-digit hexadecimal number. MD5 hashes are commonly used for security applications like secure information encryption, but are also used for validating data integrity. A hash is generated of an original data source, and later on you can generate a new MD5 hash of the data. By comparing the new hash to the original one, you can find out if the data is still valid or has errors or problems. Any differences between the two hashes signify a loss of data integrity. What Should I Use the MD5 Encryption Tool For? The MD5 tool is useful for Webmasters or software developers that might need to generate a quick MD5 has for a password, testing an authentication script, or other simple task. MD5 encryption can also be used to check on data integrity of files you have obtained which have an original signed MD5 hash to compare with. You can store just about any text string with an MD5 has. A typical MD5 hash would look like this: 6cd3556deb0da54bca060b4c39479839 In this case, this is an encrypted hash of the message "Hello, World!".

Source Code Viewer
Quickly view the full source code of any website. The Source Code Viewer Tool makes it easy to fetch and view the source code of any URL. Instead of visiting web sites one by one and digging up the source code with your browser, you can fetch the full source code for any website in one place. Enter the URL and we'll fetch the source code and display it for you to view or copy. What is a Website's Source Code? Every website uses HTML and other Web technologies to generate the web pages we see in our Web browsers. HTML is a markup language which lets Web designers define the elements and contents of a Web page, and using other languages such as CSS and JavaScript, customize and enrich each Web page. Typically, every web site you visit provides the full, unencrypted source code so that your browser can render the site. While users don't see this code, it can be viewed within the browser in most cases by selecting View Source. The source code of a website contains all the text, code elements, style elements, and other information that make up the entire page.

Webpage Size Checker
Check the size of a web page with our Web Page Size Checker Tool. The Web page size checker fetches any URL you want and returns the total size in bytes, kilobytes and megabytes, formatted so you can easily see how big the page is. How is the Size of a Webpage Determined? Web page size as reported by the Web Page Size Checker tool is based on the size of the source code for the site. This includes the full HTML source code, but not attached files or external CSS. Files that are called separately within source code should be checked individually. When you enter an URL, our tool fetches the full source code of a web page, and determines the size in kilobytes (KB) of the source code text. We then convert it into bytes and megabytes (MB) to give an idea of how hefty the web page is. Does Web Page Size Include Image Size? No, the tool only calculates source code size. This tool does not check the size of embedded images, videos, or other content that might be displayed on the page. Why Does Web Page Size Matter? The main reason that you would be concerned about web page size is for performance reasons, or for testing and website analysis. Generally on a modern broadband connection, the size of the source code is less important than the content of the page.

Website Speed Test
Test the speed of your website with our Website Speed Test Tool! Does your web site load quickly, or is it crawling along? Find out easily with the Website speed test tool - just enter any URL and our speed test will see how fast your website is loading. What Does Website Speed Test Actually Test? Every time your browser loads a web page, it makes an HTTP request to the Web server that hosts the website. Once the request is received and processed, it returns the website response with full code for your browser to render the web site. After the request is processed, it usually takes time for your browser to render the site, including fetching external files and images, and handling any scripting or formatting that takes place client-side (in your browser). The Website Speed Test Tool only checks the request/response time, which helps rule out any extra time that is spent by your browser displaying a web site. This tool lets you check how quickly your website is responding to search engines and visitors, and optimize it if necessary. Search engines don't typically penalize your website for being a little sluggish, but if your site is taking an extremely long time to respond, it might time out and hurt your rankings. Since it's always frustrating to wait for a website to load, it's wise for Webmasters to improve website load times both for visitors and for search engine bots.
