Convert GWB to PDF

A GWB lesson often needs conversion when recipients lack Interwrite Workspace or compatible classroom software. PDF makes the rendered pages easier to share, print, and archive, but it does not preserve the lesson’s editable or interactive behavior.

What the GWB format is

In the Documents category, .gwb identifies an InterWrite Workspace lesson file associated with eInstruction’s interactive-whiteboard software. It can contain multiple pages, handwriting, shapes, text, imported images, and other classroom presentation objects.

GWB is a proprietary project format used by interactive whiteboards, classroom computers, and older eInstruction or InterWrite systems. Standard office applications and archive utilities generally cannot open it. InterWrite Workspace is legacy software, so obtaining a compatible installer may be necessary if the original classroom software is no longer available.

What the PDF format is

PDF stores a document’s rendered page appearance in a widely supported format. Adobe Acrobat Reader, web browsers, Windows, macOS, and many mobile systems can display PDF files without installing Workspace.

A PDF normally retains the visible page layout, text, drawings, and images that Workspace can render. It does not retain editable Workspace objects, whiteboard tools, presentation controls, animation, audio, video, timers, or other interactive behavior unless those features are represented as ordinary page content.

How to convert a GWB file

Using InterWrite Workspace

1. Install InterWrite Workspace or the compatible eInstruction Workspace release that can open the file. Prefer the same release or a later compatible release than the one used to create the lesson.
2. Start Workspace and select File → Open, then choose the .gwb file.
3. Review each page for missing fonts, linked images, or unsupported objects. Restore the original fonts and linked media if necessary.
4. Use the available PDF command, commonly File → Export → PDF or File → Save As with PDF selected. Menu names differ between Workspace releases.
5. Set the page range and destination, then save the output as a .pdf file.
6. Open the PDF in a viewer and check page order, text, handwriting, images, cropping, and page size before distributing it.

Using print to PDF

If the installed Workspace release has no PDF export command, open the lesson and select File → Print. On Windows, choose Microsoft Print to PDF; on macOS, use the PDF menu in the system print dialog and select Save as PDF. Choose the required pages and save the printed output.

Print-to-PDF captures the pages as the application renders them. It is a useful fallback, but it produces static pages and can omit controls or objects that are not printable.

Online converter options

Generic online converters such as Zamzar or CloudConvert should not be treated as reliable GWB converters unless their current format support explicitly lists InterWrite Workspace GWB files. Most services do not interpret this proprietary structure; an uploaded file may be rejected, renamed without conversion, or rendered incompletely. Local conversion is safer for lessons containing student information, copyrighted material, or linked assets.

Quality and compatibility limits

Conversion preserves only content that the installed Workspace version can open and render. Missing fonts can change line wrapping and handwriting labels; missing linked media can leave blank objects; unsupported items may disappear. PDF cannot be converted back into the original editable GWB structure.

Keep the original .gwb file and its linked assets after exporting. If the file will not open, request the author’s fonts, media, and compatible Workspace version, or ask for an existing PDF export.
