PStill is a highly efficient, local-running desktop application designed to convert, compress, and manipulate PDF, PostScript (PS), EPS, and various image formats. Developed by Frank Siegert, it operates entirely on your local machine to keep your data secure.
Unlike standard converters, PStill can manipulate existing PDF layers, downsize files by 50–70%, combine mixed-format files, and even convert PDFs into 3D-printable STL files. Core Conversion & Manipulation Workflows
You can process files in PStill using either the graphical interface (GPStill) or via the command line. Method 1: The Graphical Interface (Drag & Drop)
The simplest way to execute a conversion is through the visual desktop window: Launch the app: Open GPStill.exe on your computer.
Import your files: Locate your source files (PDF, PS, EPS, TIFF, JPEG) and drag them directly into the main window.
Combine files (Optional): If you drop multiple different formats (e.g., one PDF and two TIFFs), PStill will automatically concatenate them into a single PDF.
Set your parameters: Click More Options to expand the window and adjust font handling, color conversion, or compression. Convert: Click Start Conversion to generate the final file. Method 2: Command Line Interface (CLI)
For developers or batch processing, the backend command engine pstill64 (or pstill) allows automation: Basic conversion: Run pstill -o output.pdf input.ps
Generate a professional CMYK PDF: Run pstill -M default -m XimgAsCMYK -o output.pdf input1.pdf Advanced PDF Features in PStill
Beyond basic file conversions, PStill is frequently used for specialized prepress and print jobs:
PDF Compression & Optimization: It re-samples images and removes duplicate embedded font data, shrinking bulky PDFs by up to 50–70%.
Font Fixing: It automatically converts incompatible TrueType or CID fonts into clean PostScript Type 1 fonts, making legacy documents printable on limited devices.
Tiling Large Pages (Poster Printing): You can split a massive single-page PDF across multiple normal-sized pages. In More Options, choose N-UP Output Options and select scripts like POSTER-tiled-A4.sl or POSTER-tiled-Letter.sl to chop the image evenly for tiling.
3D Printing Conversion: PStill can convert normal 2D vector elements directly from a PDF file into a 3D-printable STL mesh file. Where to Find It
You can download the desktop utility directly from the official Wizards.de PStill Homepage. The developer also provides comprehensive technical guides, including the complete PStill Windows Documentation Manual.
