Drag and drop HTML files here
or click to browse · Supports multiple files
Drag HTML files onto the upload area or click to browse. You can select multiple files at once. Click Check Syntax to scan all files for errors before processing. If errors are found, the tool shows which file has issues. Once files pass validation, choose your processing options and click Process Files.
Format adds proper indentation to make code readable. Remove Comments strips HTML comments (<!-- -->), CSS comments (/* */), and JavaScript comments (// and /* */). Remove Empty Lines deletes blank lines to reduce file size. You can enable any combination of these options.
The checker scans each file for unclosed tags, mismatched tag pairs, and structural issues. When errors are found, it displays the file name, line number, and a description of the problem. You must fix errors before processing can proceed.
The tool handles four comment types. HTML comments use <!-- --> syntax. CSS comments inside <style> tags use /* */. JavaScript comments inside <script> tags use both // for single lines and /* */ for multi-line blocks. Jinja2 template comments use syntax. All four get stripped when you enable Remove Comments.
Yes. The tool handles complete HTML documents with <style> and <script> blocks. CSS and JavaScript inside those blocks gets processed along with the surrounding HTML.
After processing, click Download All to get a ZIP file containing all processed HTML files. Each file keeps its original name. You can also preview individual results in the results grid.
The syntax checker lists each error with the file name and line number. Files with errors are marked and excluded from processing. Fix the errors in those files and check again, or remove them from the upload list.
No. All processing happens in your browser. Your HTML files never leave your computer.
