PS to PDF Converter
Processing entirely on your device — large files may take a moment.
PostScript Program and PDF Document exist for different jobs: PS is full PostScript — the page-description language that defined desktop publishing. Whole books were typeset as PS programs; Ghostscript remains the reference renderer. Convert to PDF when you need a fixed, print-ready layout that looks identical everywhere and cannot be accidentally reflowed or edited.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

About the PS format
PS is PostScript proper — the Turing-complete page-description language that Adobe shipped in 1984 and that desktop publishing was built on. A .ps file is a program: it draws its own pages with operators like moveto and showpage. Whole theses and books have been typeset as PS via troff and LaTeX pipelines.
Ghostscript is the reference implementation, and it runs here in your browser: PS documents convert to PDF for long-term archiving, or rasterize to PNG/JPG for the web — the same engine print RIPs license for commercial presses.
+ Strengths
- ✓Turing-complete layout control
- ✓The original device-independent print format
- ✓Reference renderer runs in-browser here
! Limitations
- −Program, not data — treat with care
- −Superseded by PDF for interchange
- −Rendering is compute-heavy for big jobs
About the PDF format
PDF (Adobe, 1993; ISO 32000 since 2008) exists for one promise: the document looks identical everywhere, forever. Fonts get embedded, layout is fixed to the point, and a contract printed from a 2003 file renders the same as one created this morning. That fixed-layout guarantee made it the standard for invoices, manuals, forms, e-books and anything with legal or financial weight.
The same design is what makes PDFs stubborn. They are meant to be presented, not edited — text lives in positioning operators rather than paragraphs, so extraction and re-flow are approximations. Scanned PDFs are worse: pure images with no text layer at all until OCR enters the picture. Still, no other format comes close for final-form document delivery.
+ Strengths
- ✓Pixel-identical rendering on every device and printer
- ✓Fonts, images and color profiles travel inside the file
- ✓Mature ecosystem: forms, signatures, annotations, encryption
! Limitations
- −Hard to edit by design — even small changes need tooling
- −Text extraction is an approximation, not a conversion
- −Scanned PDFs are images without OCR
Why convert PS to PDF?
Think of it as moving your file to the container that fits the job. Program, not data — treat with care PDF works differently: Pixel-identical rendering on every device and printer If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this PS to PDF converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
How does the layout of my document turn out?
Pages keep their proportions automatically: images are fitted to A4-equivalent pages with sensible margins, and PDF pages are rendered at high resolution. You can preview the result right in the browser before downloading.
Can I convert DWG files here?
No. DWG is a binary format without a reliable browser-side parser. Save the drawing as DXF in your CAD software first — every CAD system can export it.
Is the scale of the drawing preserved?
Coordinates are preserved exactly. The output fits the drawing extents into the page or canvas, so measurements on screen are relative — the underlying coordinates stay true.
