Fast and Free PostScript Viewer Alternatives to Adobe DistillerAdobe Distiller historically has been a go-to utility for handling PostScript (PS) and generating PDFs, but it’s not lightweight, and it isn’t free. If you work with PS files frequently — for prepress, graphic design, or software development — you’ll want fast, reliable viewers and converters that don’t cost anything and that can run on modern systems. This article surveys capable, free alternatives for viewing, converting, and troubleshooting PostScript files, explains their strengths and weaknesses, and gives practical tips for choosing and using them.
Why you might need a PostScript viewer (and not Distiller)
PostScript is a page description language used in printing and desktop publishing. Unlike image formats, PS files contain instructions for drawing text and graphics, which makes them both powerful and occasionally tricky to render. Use cases include:
- Inspecting print jobs before sending to a RIP or press
- Converting legacy PS files to PDF for sharing or archiving
- Debugging fonts, color separations, and rendering issues
- Opening .PS or .EPS attachments without a paid Adobe suite
A good viewer should be fast, accurate, and offer export or conversion tools when needed.
Key features to look for in an alternative
- Rendering accuracy: correctness with fonts, paths, blends, and spot colors
- Conversion options: to PDF, PNG, or other convenient formats
- Speed: quick load and navigation for large files
- Cross-platform support: Windows, macOS, Linux availability
- Command-line tools / scripting: useful for batch conversion and automation
- Open-source vs. proprietary: affects customizability and trust
Top fast and free alternatives
Below are robust options that cover different uses — viewing, converting, and embedding PostScript handling into workflows.
Ghostscript + GSview / Ghostview
Ghostscript is the underlying open-source PostScript and PDF interpreter many tools rely on. It’s mature, highly compatible, and available on Windows, macOS (via Homebrew), and Linux.
- Strengths: very accurate rendering, powerful command-line options, batch conversion (ps2pdf), high configurability.
- Weaknesses: command-line may intimidate newcomers; GSview GUI hasn’t been actively developed in all ecosystems (but alternatives like Ghostscript’s GSview ports or third-party front-ends exist).
Example command to convert PS to PDF:
ps2pdf input.ps output.pdf MuPDF / mupdf-gl
MuPDF is a lightweight, fast renderer that supports PDF and some PostScript workflows (often via conversion to PDF using MuPDF tools). It’s extremely fast for viewing and offers a clean interface.
- Strengths: blazing-fast rendering, small memory footprint, smooth zooming and panning, available on desktop and mobile.
- Weaknesses: PostScript support may depend on conversion steps; fewer advanced print-prep features.
Evince (Document Viewer) and Okular
Both are open-source document viewers common on Linux and available on other platforms. Evince (GNOME) and Okular (KDE) can open PS files (typically via Ghostscript integration).
- Strengths: comfortable GUI, page thumbnails, searching, annotations (Okular), and print/export options.
- Weaknesses: dependent on Ghostscript for PS rendering; Windows builds vary in maturity.
SumatraPDF
A Windows-only lightweight viewer primarily for PDF, XPS, EPUB, and DJVU, but it also handles PostScript files indirectly (when Ghostscript is installed). It’s focused on speed and simplicity.
- Strengths: very fast, minimal UI, excellent for quickly previewing files.
- Weaknesses: limited editing features; relies on Ghostscript for PS support.
Scribus (for prepress and editing)
Scribus is an open-source desktop publishing application that can import PostScript Type 1 fonts and handle PS-based workflows. It’s more of a layout tool than just a viewer, but handy when you need to prepare files for print.
- Strengths: prepress features, color management, PDF export tailored for printing.
- Weaknesses: heavier than a simple viewer; PS import/export workflows can be complex.
Conversion and command-line utilities
For many users, viewing is only part of the workflow — converting PS to PDF or images is essential. The following tools are reliable for batch processing:
- ps2pdf (Ghostscript): simple and reliable PS → PDF conversion.
- Ghostscript direct CLI: fine-grained control over resolution, color, and compatibility. Example:
gs -dBATCH -dNOPAUSE -sDEVICE=pdfwrite -sOutputFile=out.pdf in.ps - ImageMagick (convert): PS → PNG/JPEG (uses Ghostscript under the hood). Example:
convert -density 300 input.ps output.png - mupdf-tools (mutool): operations on PDFs; combine with Ghostscript for PS workflows.
Troubleshooting common PostScript issues
- Missing fonts: PS files often rely on system or embedded fonts. Use Ghostscript’s font substitution or install the missing Type 1/TrueType fonts.
- Incorrect colors or separations: ensure color profiles and CMYK handling are correct — tools like Scribus or Ghostscript color options help.
- Large file size or slow rendering: rasterize complex pages at appropriate resolution (e.g., 300–600 DPI) when preparing proofs; use MuPDF for fast on-screen viewing.
- Corrupted PS: validate with a PostScript-aware tool and try regenerating from the source application.
Recommended workflows by user type
- Casual viewer / quick checks: SumatraPDF (Windows) or MuPDF for fast, low-memory previewing.
- Converter / automation: Ghostscript (ps2pdf) or ImageMagick for scripted batch conversions.
- Prepress / designers: Scribus for layout and color control; Ghostscript for final PDF generation and RIP testing.
- Linux desktop users: Evince or Okular combined with Ghostscript for integrated GUI and backend reliability.
Quick comparison
| Tool | Platform(s) | Best for | Pros | Cons |
|---|---|---|---|---|
| Ghostscript (ps2pdf) | Win/mac/Linux | Conversion & accuracy | Powerful, scriptable, accurate | CLI learning curve |
| MuPDF | Win/mac/Linux, mobile | Fast viewing | Extremely fast, low RAM | Limited PS-native features |
| SumatraPDF | Windows | Quick previews | Lightweight, fast UI | Needs Ghostscript for PS |
| Evince / Okular | Primarily Linux (ports) | Desktop viewing | GUI features, thumbnails | Depends on Ghostscript |
| Scribus | Win/mac/Linux | Prepress/layout | Color management, PDF export | Heavier, steeper learning curve |
Practical tips for best results
- Install Ghostscript even if you prefer a GUI viewer — many viewers rely on it for accurate PS rendering.
- For archival PDFs, use ps2pdf with appropriate compatibility flags (PDF/A when needed).
- When converting to raster for proofs, choose 300–600 DPI depending on print resolution.
- Keep a small test file that reproduces the issue handy when debugging fonts or color problems.
Conclusion
You don’t need Adobe Distiller to view, convert, or prepare PostScript files for printing. For most users, Ghostscript (ps2pdf) provides the best combination of accuracy and scripting power, while MuPDF and SumatraPDF offer the fastest on-screen viewing. Designers who need print-ready controls should consider Scribus plus Ghostscript. Pick tools that fit your workflow — lightweight viewers for quick checks, Ghostscript for batch jobs and accuracy, and desktop publishing tools for final prepress work.
