Need help?PostScript (PS) to PNG Converter
A .ps file is a PostScript document — Adobe's page-description language for print and vector graphics — which most image viewers, browsers, and chat apps can't open directly. Converting it to PNG rasterizes each page into a standard image that opens anywhere. Because PNG is lossless and supports transparency, it keeps sharp text and line art clean without the blocky artifacts you'd get from a JPG.
PostScript (PS) Format at a Glance
| Property | Value |
|---|---|
| Origin | Adobe Systems, shipped 1984 |
| Type | Page-description and stack-based programming language (vector + text) |
| Latest version | PostScript 3 (1997); no longer actively developed |
| Common renderer | Ghostscript (open-source PostScript interpreter) |
| Relationship to PDF | Shares PostScript's imaging model; PDF has largely replaced it for document distribution |
| Content | Resolution-independent vector paths, text, and embedded images |
| Best for | Print workflows and high-end printers with PostScript processors |
| File extension | .ps |

How to Convert PS to PNG
- Upload Your PostScript File: Drag and drop your
.psfile onto the page or click "+ Add Files" to browse. You can queue several files and convert them with the same settings. - Set Conversion Quality (DPI): Pick a resolution under Conversion Quality. It defaults to 300 DPI (print-ready); choose 600 or 1200 DPI for large or print output, or 72-150 DPI for on-screen use. Higher DPI sharpens detail but increases processing time and file size.
- Choose Image Transparency or Background: PostScript pages have no transparency of their own, so the Image Transparency Color is set to White by default. Leave it for a clean white background, or change the color to suit where the image will sit.
- Convert and Download: Click "Convert" and download your PNG. No sign-up, no watermark — the PNG opens in any image viewer, editor, or browser.
Frequently Asked Questions
Does converting PS to PNG keep the text selectable?
No. PostScript stores text and vector paths as resolution-independent instructions, but PNG is a raster format — every page is flattened into a grid of pixels. The text stays crisp at the DPI you choose, but it becomes part of the image and can no longer be selected or searched. If you need selectable text, convert to PDF instead, which preserves the original vectors and fonts.
What DPI should I pick for a PostScript file?
Match the DPI to where the image will be used. 72-96 DPI is fine for web and screen viewing; 150-200 DPI suits documents and previews; 300 DPI (the default here) is the standard for print-quality output; and 600 or 1200 DPI is for fine line art or large-format printing. Because PostScript is vector-based, it can be rendered at any of these resolutions without the source blurring — higher DPI simply samples more pixels.
Why convert PS to PNG instead of JPG?
PNG is lossless and supports transparency, so it reproduces the sharp edges of PostScript text, logos, and line art exactly, with no compression artifacts around the strokes. JPG uses lossy compression that creates visible "mosquito" noise around hard edges and high-contrast text, which is the worst case for typeset pages. JPG only makes sense when the page is mostly a photograph; for documents and graphics, PNG (or PS to JPG only if you specifically need smaller photo-heavy files) is the better raster target.
My PostScript file has several pages — what do I get back?
PostScript renderers like Ghostscript rasterize each page separately, so a multi-page .ps document produces one PNG image per page rather than a single tall image. The pages come back numbered in order so you can keep or share just the pages you need.
Can I make the PNG background transparent instead of white?
The converter sets the Image Transparency Color to White by default because PostScript pages render on an opaque white page rather than carrying their own alpha channel. PNG itself fully supports transparency, so you can change the background color under Image Transparency to match where you'll place the image. For true cut-out transparency you'd typically remove the background in an image editor after conversion.
Is this different from converting an EPS file to PNG?
EPS (Encapsulated PostScript) is a single-page variant of PostScript built to be embedded inside other documents, so it carries a bounding box and stricter rules, while a .ps file can describe a full multi-page document. Both are rendered by the same PostScript engine. If your file is specifically .eps, use the dedicated EPS to PNG converter; for general .ps documents, this page is the right tool.
How are my uploaded files handled?
Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, and never shared or made public. The PNG you download is a standard image you can open and edit anywhere.
In your testing, how large is a typical PNG from a PostScript page?
In our testing, a single-page text-and-vector .ps document rendered at the default 300 DPI produced a PNG roughly 200-500 KB, depending on how much of the page is covered by ink. Dropping to 150 DPI roughly quarters the pixel count and the file size, while 600 DPI multiplies it — so the DPI you choose is the main lever over the output size.
