CSE HTML Validator Lite - FREE* HTML Editor and Syntax Checker
NEW! LATEST VERSION IS 8.04! Clean up your site with CSE Lite! CSE HTML Validator Lite is an award winning FREE (for personal and educational use) HTML editor and basic HTML syntax checker for Microsoft Windows 2000, XP, Vista and above. It's also adware and spyware free!
In addition to checking HTML syntax, CSE HTML Validator Lite can also:
- Check spelling.
- Quickly change all tags and attributes to lowercase.
- Automatically place quotation marks around all attribute values.
- Strip HTML tags from HTML documents, leaving only the text.
- Quickly change all the headers and/or footers of every page of your web site when you design your pages using the template tool.
If you want to automatically fix HTML problems and/or check CSS, links, and accessibility, then download CSE HTML Validator Professional Trial.
"CSE HTML Validator Lite is a superb application -- does everything I hoped and much more."
- Charles Toth, CSE HTML Validator User in Keyser, WV
"There aren't many freeware programs out there these days that are this well done and useful."
- Tim Matheson, CSE HTML Validator User
"I downloaded CSE HTML Validator Lite about two months ago and have used it ever since. It's absolutely delightful to use - and has options for everything you can think of (and a lot that you can't!). But in spite of the options, it can be used by amateurs like myself with the default values only. I have tried several other validators before and none comes near it for ease of use, flexibility, and thorough reliability. When I develop to the stage of needing the even more powerful edition, I won't bother to look elsewhere, as I'm confident this product will be of the highest standard also. Well done, and thanks."
- Phil Taylor, CSE HTML Validator User
"I just downloaded the free version and used it immediately. Already I can't say enough about this product! As soon as I have a few bucks ahead I absolutely will be upgrading, and recommending CSE HTML Validator products to everyone I know who makes web pages."
- Connie Srnka, CSE HTML Validator User
AI Internet Solutions is proud to offer CSE HTML Validator Lite, an award winning free (for personal and educational use) HTML editor and basic syntax checker! A commercial version with link checking, a more powerful built-in HTML/text editor, a batch wizard, better syntax checking, CSS syntax checking, and much more is also available (more information). CSE HTML Validator Lite v8.0 improves upon the previous lite versions, is more up to date, and includes a built-in HTML/text editor with syntax highlighting, split view, and spell checking.
NOTE: CSE HTML Validator Lite is free for personal and educational use only. It is NOT free to use for business, government, or any for-profit use unless paired with a paid license of CSE HTML Validator Standard or CSE HTML Validator Professional with the same major version number (like 8.0, 9.0, etc.). CSE HTML Validator Lite contains no ad banners or "spyware"!
If you are a professional or serious HTML developer, then we recommend that you download a trial version of CSE HTML Validator Professional instead. The lite edition is designed for casual HTML authors and is only designed to find most major and some minor problems. Furthermore, it does not include accessibility checking, CSS syntax checking, link checking, the Batch Wizard, or the integrated web browser (see the chart below). More information...
