What happens when you convert PS to PSD
- The PS is run by Ghostscript, the standard open-source PostScript interpreter, and each page is drawn by MuPDF at 150 dpi, so an A4 page becomes about 1240 by 1750 pixels, then saved as a PSD file by ImageMagick, on our conversion server.
- A one-page PS gives a single PSD; a longer one comes back as a ZIP file with one PSD per page, named page-01.psd, page-02.psd and so on, for up to 100 pages.
- The PSD has a single layer holding the rendered page; it does not rebuild the original shapes or text as editable Photoshop layers.
- PostScript is a programming language, so Ghostscript runs it in its safe mode, where the file cannot read or write anything else on the server.
- This conversion runs on our server: the file is uploaded, converted, and deleted together with the result as soon as the result has been sent back to you. Nothing is kept. Files up to 25 MB are accepted.
How to convert PS to PSD online
- Press "Choose PS files" and select one or more files, or drag them onto the box. Files up to 25 MB each can be converted.
- There are no settings to choose: the converter keeps everything the target format can hold.
- Press "Convert to PSD". The file is uploaded to our conversion server, converted in a few seconds, and deleted together with the result as soon as the result is sent back.
- Save each PSD with its download button. Our server has already deleted both your PS and the PSD by then.
Why convert PS to PSD?
PS files usually come from print jobs, printer drivers and output from Unix, LaTeX and scientific programs. People convert them to PSD because a PSD opens in Photoshop, GIMP and Photopea as a layer ready to retouch, mask or build a design on.
In short, PS is good at what it was made for, and PSD is the more practical choice when the file has to open, upload or print somewhere else. PS does not open in browsers; Ghostscript, Okular and Evince open it, and so did macOS Preview before Ventura, while PSD does not open in browsers; Photoshop opens it, and GIMP, Affinity Photo and Photopea read most PSD files.

Best settings for PS to PSD
There are no settings: every page is rendered at 150 dpi, up to the first 100 pages, with the longest side capped at 6,000 pixels.
Open the PSD in Photoshop to retouch the rendered image or place it in a design; for editable shapes, open the original in Illustrator or Inkscape instead.

About PS and PSD files
What is a PS file?
PostScript is a programming language for describing pages, made by Adobe for laser printers. A .ps file is a program that a printer or Ghostscript runs to draw each page, which is why converting it to PDF is the usual way to view or share it.
What is a PSD file?
A PSD keeps every layer, mask, adjustment and text layer separately so the work can be edited later, and stores a flattened copy of the whole picture beside them. A PSD is limited to 30,000 pixels a side and 2 GB; larger work is saved as PSB.
PS to PSD not working? Common problems
- "Files up to 25 MB can be converted." Server conversions have a size limit. Compress the images inside the file, or split it, and try again.
- "The conversion took too long and was stopped." Very long or complex files can pass the 90 second limit. Split the file and convert the parts.
- The PS will not convert. It may be damaged, or try to do something the converter blocks for safety, such as reading other files.
Convert PS to PSD from the command line
This page uses Ghostscript, which is free for Windows, Mac and Linux. The same conversion from the command line:
gs -dSAFER -dBATCH -dNOPAUSE -sDEVICE=psdrgb -r150 -sOutputFile=page-%02d.psd input.psConverting on your own computer keeps the file entirely local, which is worth it for very large or very sensitive documents. For everything else, the converter on this page does it without installing anything.
PS to PSD converter FAQ
Will I lose quality converting PS to PSD?
The pages are rendered to pixels at 150 dpi, which is sharp for reading and for printing text. The pixels are stored losslessly.
Why is the PSD a different size from the PS?
The PSD stores every pixel, while the PS stores drawing instructions, so the PSD is usually larger for detailed pages and can be smaller for simple ones.
Are my PS files uploaded?
Yes, for this conversion. A faithful PS to PSD conversion needs Ghostscript, MuPDF and ImageMagick, three open-source tools, which cannot run in a browser. The file travels over an encrypted connection, is converted in a private temporary folder, and is deleted together with the PSD as soon as the result has been sent back to you. We do not keep, read or share it.
Can I convert several PS files to PSD at once?
Yes. Select or drop as many files as you like; they are converted one after another and each gets its own download button.
How do I open a PSD file?
PSD does not open in browsers; Photoshop opens it, and GIMP, Affinity Photo and Photopea read most PSD files. PSD is common for Photoshop artwork, photo retouching, mock-ups and design files.
Is this PS to PSD converter free?
Yes. There is no sign-up and no watermark. Because this conversion uses our server, there is a fair-use limit of 25 MB per file and a number of files per hour, which stops the service being overloaded.
Can I convert PS to PSD on my phone?
Yes. It works in Safari on iPhone and iPad and in Chrome on Android. The conversion happens on our server, so it is as fast on a phone as on a computer; the PSD is saved to your Downloads folder.
