PS Converter

How to Convert PS to Any Format

1. Upload Your PS File: Drag and drop your .ps PostScript file or click "Add Files" — you can also pull one in from Google Drive or Dropbox. Batch is supported, so drop in several PostScript files and each one converts on its own.
2. Pick an Output Format and Compression Type: Choose the target from the format dropdown — PDF, DOC, DOCX, or back out to PS, plus image targets like JPG, PNG, TIFF, WebP, and BMP. When the output is PDF, the Compression Type preset controls the size-versus-quality trade-off: Screen (Best) for the smallest on-screen file, Ebook for a middle ground, Default, Printer, and Prepress for higher-resolution print output.
3. Adjust Paper Size and Layout (Optional): For document targets you can set the paper size (A4, Letter, Legal, A3, and more), page layout (Portrait or Landscape), and margins before converting.
4. Convert and Download: Click Convert. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared.

Popular PS Conversions

• PS to JPG — rasterize pages to flat JPEG images for email or the web
• PS to PNG — sharp lossless raster pages, good for line art and screenshots
• PS to EPS — repackage a figure as Encapsulated PostScript for embedding
• PS to TIFF — high-resolution raster pages for print or archiving
• PS to DOCX — pull the content into an editable Word document

Why Convert a PS File?

PostScript (.ps) is Adobe's page-description language, designed by John Warnock, Charles Geschke, and colleagues between 1982 and 1984 and released in 1984 — it shipped to the world the next year inside Apple's LaserWriter. A PS file is not an image or a document in the everyday sense: it is a small program in a stack-based language that tells a printer or imagesetter exactly how to draw each page, vector by vector. That made it the backbone of professional printing for decades.

The catch is that nothing reads PostScript natively anymore. To see a .ps file you need a PostScript interpreter such as Ghostscript, because the page only exists once the program is executed. PDF — which Adobe built directly on top of PostScript — is essentially the same drawing instructions laid out, frozen, and wrapped so any phone, browser, or e-reader can open it without running a program. That is why PDF overtook PostScript for everything except the print room. Common reasons people convert away from PS:

• Sharing and viewing (PDF) — Converting PS to PDF is the default move. It keeps the vector layout, fonts, and graphics intact but makes the file openable on any modern device without Ghostscript installed.
• Putting a page into a web page or chat (JPG / PNG) — Rasterizing each PS page to JPG or PNG turns the print description into a flat image you can drop into a document, email, slide, or message.
• Reusing a single figure (EPS) — If the .ps holds one illustration you want to embed in another document, Encapsulated PostScript (EPS) wraps it with a bounding box so design tools can place it.
• Editing the text (DOC / DOCX) — Converting toward Word gets the content into an editable document rather than a fixed, print-bound page.
• Print-shop output (TIFF / high-resolution PDF) — For prepress, a high-DPI TIFF or a Prepress-preset PDF preserves the detail an imagesetter needs.

PS vs PDF vs EPS

Frequently Asked Questions

What opens a .ps file?

On its own, almost nothing on a typical computer opens a .ps file directly — it is a PostScript program that has to be executed by an interpreter. Ghostscript (and front-ends like GSview or Okular) can render it, and Adobe applications such as Acrobat, Illustrator, and Photoshop can import it. macOS Preview can also open PostScript by converting it to PDF first. For everyone else, the simplest path is to convert PS to PDF and open the result in any browser or PDF reader.

Is PS to PDF lossless?

For the page geometry, yes — the vector drawing commands, text, and fonts are reproduced faithfully, so the layout matches the original PostScript exactly. Where size and quality trade off is in embedded raster images: the Compression Type preset decides how aggressively those are downsampled. Screen (Best) targets the smallest on-screen file, while Printer and Prepress keep images at higher resolution for print. Vector content and text stay crisp at any preset.

What is the difference between PS and EPS?

A .ps file is a complete PostScript program that can describe a multi-page document and tells the printer to eject each page. EPS (Encapsulated PostScript) is a restricted, self-contained variant meant to hold a single figure: it carries a %%BoundingBox comment describing the figure's exact dimensions so design and layout tools can place and scale it inside another document. Convert PS to EPS when you want to reuse one illustration; convert PS to PDF when you want to view or share whole pages.

Why has PDF replaced PostScript?

PDF was built by Adobe directly on PostScript's imaging model, but with a crucial difference: a PDF is already laid out and resolved, so it opens instantly in any reader without running a program. PostScript has to be interpreted every time, which is slower and needs Ghostscript or a PostScript printer. PDF also added features PostScript never had — interactivity, compression, incremental viewing, and an ISO standard (ISO 32000). PostScript still lives on inside print workflows, but for sharing and viewing, PDF won.

Which Compression Type should I choose when converting PS to PDF?

It depends on where the PDF is going. Screen (Best) produces the smallest file and is ideal for email, web, or on-screen reading. Ebook is a balanced middle ground. Printer and Prepress keep embedded images at higher resolution for physical printing and professional prepress, at the cost of a larger file. These map to Ghostscript's standard quality presets, which mainly change how embedded raster images are downsampled — vector text and line art stay sharp either way.

How large can the PS file I convert be?

There is no fixed per-file cap, and you can queue several PostScript files in one batch. Because conversion runs on our servers rather than in your browser, the practical limit is upload size and your connection speed. In our testing, a single-page text-heavy .ps file converts to PDF in a second or two; large files with many high-resolution embedded images take longer mostly because of the upload. Files are deleted automatically after a few hours, and nothing is shared or made public.
