Free PS file to PDF converter

Convert PS to PDF Online

Convert a PostScript .ps file into a standard PDF that opens in browsers and PDF readers. Multi-page PS files keep their document pagination, while text and vector artwork remain high-resolution where the source permits.

Key Points

  • Multi-page PostScript input
  • Vector PDF output
  • Selectable text where fonts permit
  • No document-processing upload

Capabilities

  • Retain PostScript page dimensions
  • Use embedded fonts and flag substitutions
  • Preserve raster images at source quality
  • Preview the generated PDF before download

Open legacy print files anywhere

PostScript is common in publishing, print drivers and older technical workflows, but modern browsers do not display it directly. PDF provides a portable replacement without turning every page into an image.

  • Share print output with people who do not have a PS viewer
  • Keep diagrams and line artwork sharp when zoomed
  • Review multi-page printer output in a normal PDF reader
  • Create a separate PDF without modifying the source file

Converted privately in your browser

A version-pinned Ghostscript WebAssembly engine interprets the selected PostScript bytes in a dedicated browser Worker and writes the PDF in local memory.

  • The PS file is not sent to a document-processing API
  • No registration, watermark or print dialog
  • SAFER file-access restrictions remain enabled
  • Conversion warnings are shown instead of silently ignored

How to convert PS to PDF

Select a PostScript document, convert it with the local engine, inspect the PDF and download the result.

1

Choose a PS file

Select one .ps file from a print, publishing or technical workflow.

2

Convert locally

Ghostscript interprets the PostScript instructions and writes a PDF in browser memory.

3

Inspect the pages

Use the PDF preview to confirm pagination, fonts, page orientation and artwork.

4

Download the PDF

Save the generated PDF as a separate file on your device.

Practical guide

What to know before you start

A PS file is a PostScript program that can describe one or many printed pages. KissPDF interprets it with Ghostscript pdfwrite, preserving text and vector graphics where possible instead of turning each page into an image.

PS documents can contain multiple pages

Unlike EPS artwork, a PostScript print job can contain a complete paginated document. The PDF output follows the page boundaries, sizes and orientation declared by the PostScript program.

  • One PS file becomes one PDF
  • Each showpage operation can create a PDF page
  • Page geometry is determined by the source program

Fonts and external resources matter

Embedded fonts normally travel with the document. If a requested font is missing, Ghostscript substitutes an available font, which can alter character widths. A PS program that tries to load an external file cannot use a resource that was not selected with the source.

  • Embed fonts for the closest match
  • Self-contained files convert most reliably
  • Review typography before print production

Text and vector content remain usable

Ghostscript pdfwrite creates normal PDF pages rather than a tall screenshot. Vector paths stay scalable, compatible text can remain selectable, and raster images retain their source detail unless the PostScript program transforms them.

  • No forced page rasterization
  • No intentional image downsampling
  • PDF 1.7 output

A browser-based ps2pdf workflow

The command-line ps2pdf utility also uses Ghostscript to convert PostScript. This page provides that workflow through a browser interface, letting you convert and preview a .ps file without installing desktop software or using a print dialog.

  • Works in current desktop browsers including Chrome
  • Preview the converted PDF before saving it
  • One source PS file is converted at a time

Frequently asked questions

Clear answers based on how this tool actually works.

How do I convert a PS file to PDF?

Choose one .ps file. KissPDF converts it locally, opens the generated PDF preview, and provides a PDF download button.

Can I convert a .ps file to PDF in Chrome?

Yes. Open this page in a recent version of Chrome, select the .ps file, inspect the PDF preview, and download the result. No print dialog is required.

Is this an online alternative to ps2pdf?

Yes. Both workflows use Ghostscript to interpret PostScript and write PDF output. KissPDF runs the conversion through WebAssembly in your browser instead of requiring a local command-line installation.

Does PS to PDF preserve multiple pages?

Yes. A standard multi-page PostScript document is converted into a PDF with the corresponding pages.

Does the converter keep vector graphics?

Yes, Ghostscript pdfwrite normally retains compatible text and vector operations as PDF content rather than rasterizing the entire page.

Why does a font look different after conversion?

The PS file may reference a font without embedding it. When that font is unavailable, the conversion engine must use a substitute.

Is my PS file uploaded?

No. The selected file is processed in browser memory by a local WebAssembly Worker.

Can this create PDF/A or PDF/X?

This page creates a standard PDF. Archival PDF/A and print-production PDF/X require additional profiles, metadata and validation.
