Introduction
This section represents a reference for every document and image file format supported by PrizmDoc.
PrizmDoc detects most of the formats automatically, except the formats with poor signature or no signature at all. Such formats are detected by the file extension.
PrizmDoc Viewer disables JavaScript execution for any HTML file conversion.

CAD Formats
| Format | File Extension | Auto Detection |
|---|---|---|
| AutoDesk AutoCAD format (version 2.5 through 2023) | *.dwg, *.dxf |
Yes |
| AutoDesk Design Web format | *.dwf |
Yes |
| MicroStation Drawing format (V7 and V8) | *.dgn |
Yes |
Web Formats
PrizmDoc Viewer disables JavaScript execution for any HTML file conversion.
| Format | File Extension | Auto Detection |
|---|---|---|
| HyperText Markup Language format | *.html, *.htm |
Yes |
| Extensible HyperText Markup Language format | *.xhtml, *.xhtm |
Yes |
Most of the HTML files are auto-detected by searching for specific tags. Although html tags usually denote a web page, they neither guarantee that the file is a web page, nor they are required for rendering a file as a web page. Such incompliant files might not be recognized as HTML, but will still be rendered as HTML in case if they are identified as such by the file extension.
Email Formats
| Format | File Extension | Auto Detection |
|---|---|---|
| Microsoft Outlook format | *.msg |
Yes |
| Outlook Express Email format | *.eml |
No |
EML files are not auto-detected, but identified by file extension because EML is a plain text in MIME format which does not allow reliable auto-detection. Currently PrizmDoc supports rendering of the following email headers: From, Subject, To, CC, BCC, Sent, and Attached.
Text Formats
| Format | File Extension | Supported by Microsoft Office renderer | Auto Detection |
|---|---|---|---|
| Text format | *.txt |
No | No |
| Comma-Separated Values format | *.csv |
Yes | No |
Text and CSV files are not auto-detected, but identified by file extension because both are plain text formats with no file signature. These formats however assume different rendering style. While Text is rendered plain, the CSV is rendered like a spreadsheet. We distinguish them by file extension.
Medical Image Formats
| Format | Compression | File Extension | Auto Detection |
|---|---|---|---|
| Digital Imaging & Communication in Medicine format | Uncompressed, JPEG, RLE |
*.dcm, *.dicom, *.dcim, *.dicm |
Yes |
Currently PrizmDoc auto detects DICOM Specification Part 10 compliant files only. Auto-detection of the legacy DICOM files (without DICOM File Meta Information) is not supported, therefore the legacy DICOM files are detected by the file extension. Currently PrizmDoc does not support conversion of DICOM format to SVG.

- PrizmDoc Server running on Windows supports vector and raster content in Windows Metafile (WMF) and Enhanced Metafile (EMF) formats. On Linux platforms, only WMF and EMF files with a single raster image are supported; all others are rejected.
- Dr. Halo (CUT) format cannot be reliably auto-detected due to its poor file signature, therefore it is identified by file extension.
- PrizmDoc does not support conversion of CAL/CALS, CUR, DCX, IMG, PCT/PIC/PICT, PSD/PSB, RAS, TGA/TPIC and XWD formats to SVG.
