PS to JPG Converter
A PS file holds a PostScript page — Adobe's print-oriented page-description language, full of vector outlines and text drawing commands that most image viewers and web browsers can't open directly. Converting PS to JPG rasterizes that page into a flat, universally viewable photo-style image: the text and vectors are baked into pixels at the resolution you choose, so the result opens anywhere but is no longer selectable or re-editable as text.

| Compression | Lossy, typically around 10:1 to 20:1 |
| Color | 24-bit RGB (no transparency channel) |
| Resolution | Fixed pixel grid, set at conversion time |

How to Convert PS to JPG
- Upload Your PostScript File: Drag and drop your
.psfile onto the page or click "+ Add Files" to browse for it. - Set the Conversion Quality (DPI): Open Advanced Options and pick a DPI under Conversion Quality. The default is 300 DPI (print quality); choose 72–150 for a smaller on-screen image or 600–1200 for fine detail.
- Adjust Quality Preset and Background: Set the Image Compression Quality Preset (default Very High) to trade file size against fidelity, and pick a background Color (default White) to fill PostScript's transparent areas.
- Convert and Download: Click "Convert" and download the JPG. No sign-up, no watermark.
Frequently Asked Questions
Why does my PostScript text become un-selectable in the JPG?
Because rasterizing turns the page into pixels. PostScript describes text and vectors as drawing instructions, but a JPG is a fixed grid of colored dots with no notion of "letters" or "shapes." Once converted, the words look identical but can't be selected, searched, or re-flowed. If you need the text to stay live, convert to PS to PDF instead, which preserves the vector and text content.
What DPI should I choose for PS to JPG?
DPI sets how many pixels the page is rendered at, so higher DPI means a larger, sharper image and a bigger file. For viewing on a screen or attaching to an email, 96–150 DPI is usually enough. The 300 DPI default matches typical print resolution, and 600 or 1200 DPI is for cases where you need to zoom into fine line art or small type without it looking blocky.
Will a multi-page PostScript file produce one JPG per page?
A JPG holds a single image, so a PostScript document with several pages is rendered one image per page rather than one stacked file. If you specifically need every page kept together in one file, a multi-page format such as PDF or TIFF is the better target — JPG is best when you want each page as its own standalone image.
Does converting PS to JPG lose quality?
Two things happen. First, vectors that were resolution-independent become a fixed pixel grid, so detail beyond your chosen DPI is gone. Second, JPG compression is lossy, so it discards some fine data to shrink the file. At the Very High quality preset and 300 DPI the loss is hard to notice on a normal page; it becomes visible only if you push the quality preset low or render at a coarse DPI.
Why can't I just open a .ps file directly?
PostScript was built to be interpreted by printers and dedicated software, not shown as a picture, so most modern image viewers and web browsers have no built-in PostScript renderer. Tools like Ghostscript, Adobe Acrobat, GSView, or macOS Preview can open it, but converting to JPG (or PDF) is the simplest way to make the page viewable on any device without installing extra software.
Should I convert PS to JPG or to PDF?
Choose JPG when you want a flat picture of the page to drop into a chat, slide, or web page, or when the recipient just needs to see it. Choose PDF when you need the text to stay selectable and searchable, the layout to scale crisply when zoomed, or several pages kept in one file. In our testing, a single text-heavy PostScript page rendered to JPG at 300 DPI lands in the low hundreds of kilobytes, while the same page as PDF stays vector and noticeably smaller.
Can I make the resulting JPG smaller?
Yes — two levers control size. Lowering the DPI shrinks the pixel dimensions, and lowering the Image Compression quality preset increases compression. If you've already converted and just need a smaller file, run the result through Compress JPG to target a specific size without re-rendering the PostScript.
Are my uploaded PostScript files kept private?
Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared or made public. The JPG you download is a standard image you can store and reuse anywhere.
