• Advanced Text Editor. Provides syntax highlighting for multiple programming and markup languages. The coloring distinguishes elements, attributes, values, and comments. Supports code folding to hide and show sections. The line number is displayed next to each line of code. The autocomplete feature suggests tags and properties while typing. Automatic indentation organizes the code structure. Bookmarks allow quick navigation to specific points. Multi-caret editing enables simultaneous changes in multiple locations.
• HTML and CSS Validation. Checks code compliance with W3C standards. The internal validator detects syntax and structure errors. It flags unclosed tags, deprecated attributes, and incorrect nesting. For CSS, it checks the validity of properties and selectors. Generates detailed reports with the location of each problem. Warnings and errors are displayed in a dedicated panel. Allows validation against different HTML versions like HTML5 and XHTML. Manual or automatic correction follows defect identification.
• Integrated FTP Connectivity. Establishes a direct connection with remote servers to transfer files. Manages local and remote files from a unified explorer. Synchronizes entire folders between the local system and the server. Transfer is done via drag-and-drop or specific commands. Supports secure FTPS connections for data protection. Maintains multiple connection profiles with saved parameters. Allows direct editing of files on the server without prior download. The transfer log documents all operations performed.
• Snippet Library. Stores reusable blocks of code for quick insertion. Organizes snippets by categories and programming languages. Customizable placeholders adapt the inserted code. Search filters snippets by name or content. Allows importing and exporting complete snippet collections. Insertion is triggered by customizable key combinations. Snippets can contain plain text, HTML, CSS, or JavaScript. Speeds up writing repetitive structures and common patterns.
• Spell Checking. Examines the text contained within the code for spelling errors. Automatically ignores tags, attributes, and code properties. Supports multiple dictionaries for different languages. Underlines unrecognized words with a red squiggly line. Suggests alternative corrections from the context menu. Allows adding custom words to the user dictionary. Operates in real-time during writing or on demand. It is configurable for specific areas like comments and textual content.
• Project Navigation and Exploration. Presents the file structure in a dedicated side panel. Displays folder hierarchy and all contained files. Filters the view by specific file extensions. Quick preview shows content without fully opening the file. Project statistics report the number of files and lines of code. Project search locates text in all files simultaneously. Recent files history allows quick access. Integration with basic version control manages changes.
• Search and Replace Tools. Locates text strings within the current document or multiple files. Replace modifies found text with new content. Supports regular expressions for complex search patterns. Matching can be case-sensitive or case-insensitive. Incremental search highlights results while typing the term. Replace with confirmation requests authorization for each change. The count function calculates the total number of occurrences. Operates in all open documents or the entire project.
• Live Preview. Displays the result of the HTML code in an internal viewing panel. Automatically updates the view when modifying the source code. Toggles between design view and rendered source code view. Includes emulation of different screen sizes and devices. Print preview shows how the document would look printed. Allows interaction with elements like forms and links. Preview generation does not require saving the file beforehand. Displays rendering errors and browser warnings.
• Plugins and Extensibility. Adds functionality through external modules. The architecture allows developing custom plugins. Plugins can add tools, panels, and menu commands. Plugin management enables or disables modules individually. There are plugins for integration with external systems and APIs. Plugin updates keep functionality up-to-date. Official plugins are developed by the program's team. Developer documentation details the creation process.
• Macro Recording and Playback. Captures sequences of editing actions for automation. Stores macros in files for later use or distribution. Playback executes the complete sequence of recorded actions. Assigns custom key combinations for frequent macros. Manual macro editing adjusts specific parameters. Support for complex macros with conditional logic. Macros can contain editing, navigation, and formatting commands. Reduces repetition of identical tasks in multiple files or projects.
• Code Formatter and Beautifier. Automatically rearranges code to improve readability. Applies consistent indentation according to configured rules. Sorts and organizes attributes within HTML tags. In CSS, arranges properties in logical order and groups rules. In JavaScript, controls spaces, line breaks, and semicolons. Removes unnecessary formatting and redundant whitespace. Formatting options are customizable per language. Produces structured code that complies with style conventions.
• Integrated Color Picker. Identifies and selects colors for use in CSS properties. Extracts color values directly from code or the screen. Stores custom color palettes for specific projects. Converts between different formats like HEX, RGB, HSL, and names. The color spectrum allows visual selection with hue adjustment. The magnifier increases precision when selecting colors from the screen. Recently used colors are kept in a quick history. Automatic insertion of the color value at the cursor position.
• Document Templates. Provides predefined structures for different file types. Includes templates for HTML5, XHTML, CSS, and JavaScript documents. Templates contain metadata, basic structure, and comments. Generate documents with correct DOCTYPE declaration and appropriate charset. Specialized templates for common frameworks and libraries. Allow creation of custom templates with specific content. Template selection occurs when creating a new file. Ensures consistency in the initial structure of all documents.
• File Comparison and Merging. Detects differences between two versions of the same file. Presents changes side-by-side with highlighting of modifications. Navigation between differences with previous and next commands. Manual merging selects which changes to keep from each version. Supports comparison of local and remote files. Generates difference reports in plain text format. The highlighting feature shows added, deleted, and modified lines. Essential for code review and change control.

The development of HTMLPad began in the year 2001. The application was created by Blumentals, a company based in Latvia. The development team concentrates efforts on tools for web programmers. The program is written primarily in Delphi, using Embarcadero's development environment. Initial versions focused on basic HTML editing with validation.
