WPG to PNM Converter
Processing entirely on your device — large files may take a moment.
Convert PNM files to modern formats, or write PNM when the receiving pipeline auto-detects the family. If your files are still in WPG format, this page is the shortcut: WPG is the embedded-graphics format of WordPerfect Office — vector and bitmap drawings from 1990s documents, still found in legal and government archives.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

About the WPG format
WPG is the graphics format of WordPerfect Office, the word processor that dominated North American law offices and government agencies through the 1990s. WPG files embed both vector line art and bitmaps, which is why they still surface inside archived legal filings and municipal records.
Nothing modern reads WPG natively. Converting WPG to PNG rescues those drawings into a format that drops into any document, wiki or image library without a WordPerfect installation.
+Strengths
- ✓Holds both vector and bitmap art
- ✓Compact for its era
- ✓Widely present in legal archives
!Limitations
- −Legacy format, no modern support
- −Vector data may rasterize on convert
About the PNM format
PNM is not a format of its own — it is the family name for PBM/PGM/PPM, and files carrying the .pnm extension simply expect the reader to sniff the P1-P6 magic and branch accordingly. It exists because Unix tools always preferred one extension that means "any of these".
This converter auto-detects the member format on input and writes the full-color P6 flavor on output, so a .pnm file turns into anything modern without a separate PBM/PGM/PPM detour.
+Strengths
- ✓One extension for the whole netpbm family
- ✓Auto-detection on both read and write
- ✓Same bulletproof simplicity as PBM/PGM/PPM
!Limitations
- −Ambiguous by design — tools must sniff
- −Inherits all the size downsides of the family
- −Some tools only accept specific members
Why convert WPG to PNM?
Think of it as moving your file to the container that fits the job. Legacy format, no modern support PNM works differently: One extension for the whole netpbm family If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this WPG to PNM converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Will I lose quality converting WPG to PNM?
No — PNM is a lossless format, so every pixel of the converted image matches your original WPG file. You can also adjust the quality/size balance before converting when the target format supports compression.
What happens to EXIF data and other metadata?
Conversions here re-encode the image, and re-encoding generally does not carry the original metadata over. If the EXIF data of your WPG files matters (camera model, GPS, timestamps), keep the original file as the master and treat the converted copy as the shareable version.
Will transparent areas survive the conversion to PNM?
Transparency is kept whenever PNM actually supports an alpha channel. If the target format has none (like JPG), transparent areas are flattened onto a white background — that is a property of the format, not of this tool.
