How to Use Wonderwebware RTF to HTML Converter: A Step-by-Step GuideConverting RTF (Rich Text Format) documents to clean, web-ready HTML is a routine task for developers, content editors, and anyone who needs formatted text on web pages. Wonderwebware RTF to HTML Converter is a tool designed to simplify that process, preserving text styling, images, lists, tables, and more while producing HTML that’s suitable for embedding in webpages or further processing.
This guide walks through installation, basic and advanced conversion workflows, tuning options for cleaner HTML, troubleshooting common issues, and practical tips for integrating the converter into a content pipeline.
What the converter does (and when to use it)
Wonderwebware RTF to HTML Converter parses RTF files and emits corresponding HTML markup. It’s useful when:
- You receive content in RTF from word processors and need to publish it online.
- You want to automate bulk conversions.
- You need programmatic control over how specific RTF constructs (fonts, colors, tables) map to HTML/CSS.
Key capabilities: preserves basic formatting (bold, italic, underline), paragraph styles, lists, tables, inline images (where supported), and basic font/size information. Output can be tailored for inline styles or class-based styling for easier theme integration.
Getting started: installation and setup
- System requirements
- Windows, macOS, or Linux (check the vendor page for exact supported versions).
- .NET runtime or Java runtime if the tool version requires it (some builds are standalone executables).
- Download and install
- Obtain the converter from Wonderwebware’s official download page or their distribution channel.
- Unpack the archive or run the installer.
- If the converter is a CLI tool, ensure its executable is in your PATH; if it’s a library, add it to your project dependencies.
- Licensing
- Verify licensing terms — there may be a trial, free tier, or paid license that unlocks batch processing or developer libraries.
Step-by-step: basic GUI conversion (if using the desktop app)
- Launch the Wonderwebware RTF to HTML Converter application.
- Open your RTF file: File → Open → select document.rtf.
- Choose output settings:
- Output format: HTML5 or legacy HTML.
- Styling mode: inline styles or CSS classes.
- Image handling: embed as base64 or export as separate files.
- Preview: use the built-in preview pane to inspect the converted HTML visually.
- Click Convert or Export to save the resulting HTML file.
- Open the generated .html in a browser to confirm layout and images.
Step-by-step: command-line usage
Many users prefer CLI for automation. Example usage patterns (adjust for the real executable name and flags):
Basic single-file conversion:
wonderrtf2html -i document.rtf -o document.html
Batch convert all RTF files in a folder:
wonderrtf2html -i *.rtf -o output-folder/
Options you’ll commonly use:
- –style inline | classes — choose whether formatting is inline or uses classes.
- –images embed | separate — embed images as base64 data URIs or save them to an images folder.
- –preserve-fonts true|false — keep font-family declarations.
- –table-handling simple | complex — controls how nested or merged table cells are represented.
Check the tool’s –help output for exact flags:
wonderrtf2html --help
Integration into a development pipeline
- As a library
- If Wonderwebware provides a library (for .NET, Java, or Node), add it to your project.
- Use its API to load RTF content and request HTML output. Typical pseudo-code:
var converter = new RtfToHtmlConverter(); var html = converter.Convert(rtfString);
- As a command-line step
- Add a build step in your CI to convert documentation written in RTF to HTML for deployment.
- Use shell scripting to handle multiple files, rename outputs, and move images.
- Server-side conversion
- Protect server resources; convert asynchronously for large files.
- Validate RTF input and sanitize the resulting HTML before storing or serving.
Tuning output for cleaner HTML
- Prefer CSS classes over inline styles if you want consistent theming across documents.
- Strip unnecessary font, color, or size tags when you prefer site-wide typography.
- Normalize list formatting — convert RTF list styles into semantic
- /
- structures rather than relying on style attributes.
- Flatten nested spans where possible to reduce markup bloat.
- For images, choose base64 embedding for small inline graphics and separate files for large images to keep HTML lean.
Handling images, tables, and special elements
- Images: Verify whether images are embedded in the RTF. If so, choose whether to export them to separate image files or embed as base64. Check image formats after conversion (PNG/JPEG).
- Tables: Some complex RTF tables may use nested cells or merged cells. Use the converter’s advanced table settings to preserve colspan/rowspan.
- Footnotes/endnotes: Confirm support — you may need a post-processing step to convert footnotes into anchors or inline references in HTML.
- Hyperlinks: Should convert to by default; check for mailto: and internal anchors.
Common problems and fixes
- Messy inline styles: switch to class-based styling or run a post-processing CSS cleanup script.
- Missing images after conversion: ensure you selected “export images” and check output directory paths.
- Broken lists or table structure: try the “complex table handling” option or open the RTF in a word processor to simplify formatting then reconvert.
- Encoding issues (weird characters): ensure UTF-8 output encoding. Use a text editor that displays encoding and change to UTF-8 if necessary.
Example workflow: converting and embedding into a webpage
- Convert document.rtf:
wonderrtf2html -i document.rtf -o document.html --style classes --images separate
- Copy document.html to your website’s content folder and images to /assets/images/doc1/.
- Add or import the generated CSS that contains class definitions, or create site-level CSS to style the classes.
- Open the page in a browser and tweak CSS for responsive layout.
Security and sanitization
Always sanitize converted HTML before displaying user-provided RTF on public sites. Use an HTML sanitizer that removes scripts, event handlers, and dangerous attributes while preserving formatting tags like
