Extract text from Nokia and Nikon images (NPG)
To convert NPG images to another format, you need Adobe Photoshop or other Raster Image software.
To convert other file formats to the "Proprietary Device Photo" file type, you need software like Adobe Photoshop or a similar tool.
The .npg file extension is primarily associated with legacy mobile and digital imaging formats, specifically the Nokia Picture JPEG and the Nikon Picture Format. These files are essentially proprietary wrappers around standard bitmap data, used by older Nokia handsets and specific Nikon imaging workflows to store photos with embedded metadata or device-specific headers.
Because .npg is a non-standard format, modern operating systems like Windows 11 and macOS do not generate thumbnails for them, and standard viewers like Microsoft Photos will fail to open them. Users often encounter these files when recovering data from old backups or SD cards. The most pragmatic solution is to convert them to widely supported formats. For photography, convert to JPG to maintain EXIF data compatibility. For archiving without quality loss, PNG is the superior choice.
Convert.Guru analyzes your NPG file, detects the exact format, and lets you read the text inside.
Users also converted PNG, JPEG, PDF, JPG, ZIP, PEO, MISS and MRES files.
If you want to convert NPG file to JPG, PDF, PNG, GIF, BMP, TIFF, TIF, WEBP, ICO, CUR, PSD or PSB, you can use Adobe Photoshop or similar software from the "Legacy Mobile Imaging" category. In the File menu, look for Save As… or Export….
To convert RAW, PNG, AI, NEF, PSB, DNG, SVG, GIF, EPS, JPG, ARW or PDF files to NPG, try Adobe Photoshop or another comparable tool in the "Legacy Mobile Imaging" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our NPG converter.
