How to Open PCX Files: Best PCX Viewer Tools in 2025PCX is an older raster image format introduced by ZSoft for PC Paintbrush in the mid-1980s. Although uncommon today, PCX files still appear in legacy archives, scanned documents, game assets, and graphic collections. This guide helps you open PCX files safely and effectively in 2025, presents the best PCX viewer tools across platforms, and offers tips for troubleshooting and converting PCX images.
What is a PCX file?
PCX (Picture Exchange) is a raster graphics file format that supports indexed color, grayscale, and RLE compression. It was widely used in DOS and early Windows-era graphics programs. Typical characteristics:
- File extension: .pcx
- Compression: Run-length encoding (RLE)
- Color modes: Palette-based (up to 256 colors) and truecolor variants in later implementations
- Typical use: Legacy images, game sprites, scanned art
Why you might still encounter PCX files
- Old software, game archives, and demo scene collections often retain PCX assets.
- Digital preservation projects include PCX images in scanned historical materials.
- Some specialized workflows or embedded devices export images in PCX for compatibility.
How to open PCX files — quick options
- Use a modern image viewer with legacy format support.
- Convert PCX to a more common format (PNG, TIFF, JPEG) if you need broad compatibility.
- Use command-line tools for batch conversion or processing.
Best PCX viewer tools in 2025 (by platform)
Below are recommended tools chosen for compatibility, ease of use, and active maintenance.
Windows
- IrfanView — Lightweight, fast, supports PCX viewing and batch conversion; plugin ecosystem.
- XnView MP — Cross-format support, good for browsing large collections and batch operations.
- Paint.NET (with plugin) — For simple editing; requires a plugin to open some PCX variants.
macOS
- XnView MP — Native macOS build with the same strengths as on Windows.
- GraphicConverter — Longstanding macOS app with broad format support and conversion features.
Linux
- XnView MP — Available as a binary and works on many distros.
- GIMP — Open-source editor that can open PCX and export to modern formats.
- ImageMagick (display/convert) — Command-line power for viewing and batch conversions.
Cross-platform / Web
- IrfanView alternatives are mostly platform-specific, but XnView MP and ImageMagick work across OSes.
- Web-based converters/viewers — Useful for single-file quick views (consider privacy before uploading).
Command-line & Libraries
- ImageMagick / GraphicsMagick — convert, mogrify, display for scripting bulk operations.
- libpng + custom converters — for developers extracting PCX images in pipelines.
How to open a PCX file — step-by-step examples
Windows (IrfanView)
- Install IrfanView from the official site.
- Open IrfanView, then File → Open → select your .pcx file.
- To convert: File → Save As → choose PNG or TIFF.
macOS (XnView MP)
- Install XnView MP for macOS.
- Drag the .pcx file into the app or use File → Open.
- Use Export for conversion options.
Linux (ImageMagick)
- View:
display image.pcx - Convert to PNG:
convert image.pcx image.png
GIMP (all platforms)
- Open GIMP → File → Open → select .pcx.
- Edit as needed; File → Export As → choose PNG/JPEG.
Converting PCX to modern formats (recommendations)
- For lossless preservation: convert to PNG or TIFF. PNG preserves exact pixel data for indexed/truecolor images without lossy compression. TIFF is useful for archival workflows and multi-page or high-bit-depth needs.
- For web or smaller files: convert to PNG or high-quality JPEG (if truecolor and smaller size needed).
- Use ImageMagick for batch jobs:
mogrify -format png *.pcx
Troubleshooting common PCX issues
- File won’t open: confirm the extension is actually a PCX and the file isn’t corrupted. Try multiple viewers (IrfanView, XnView, GIMP).
- Palette appears wrong: some PCX files store palettes at the end of the file; use a viewer known to handle legacy variants (IrfanView, GIMP).
- Color shifts: convert to PNG with ImageMagick or open in GIMP and manually adjust the palette.
- Large batches: use ImageMagick or XnView MP batch processing to convert many files.
Privacy and safety considerations
- Avoid uploading sensitive or proprietary PCX files to unknown web converters. Use local tools (IrfanView, XnView, ImageMagick, GIMP) when possible.
- Keep backups of originals before batch conversions or automated processing.
Recommendation summary
- Best lightweight Windows viewer: IrfanView.
- Best cross-platform viewer and batch tool: XnView MP.
- Best open-source editor for fixes: GIMP.
- Best command-line/bulk tool: ImageMagick.
If you want, I can: convert a PCX sample you provide, produce command-line scripts for bulk conversion tailored to your OS, or recommend the exact download links and install steps for one of the tools above.
