What happens when you convert WebP to PS
- ImageMagick, the open-source image toolkit, reads the WebP on our conversion server and embeds it in a PostScript page.
- PS has no transparency here, so transparent areas are filled with white.
- The PS holds the picture as pixels. It does not turn the image into vector shapes, so it will not scale up without softening.
- Photos are turned upright using the rotation stored in them, so the result is always the right way up.
- 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 WebP to PS online
- Press "Choose WebP 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 PS". 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 PS with its download button. Our server has already deleted both your WebP and the PS by then.
Why convert WebP to PS?
WebP files usually come from images served by websites to save bandwidth. People convert them to PS because PostScript is what many printers, print shops and Unix print systems accept directly.
In short, WebP is good at what it was made for, and PS is the more practical choice when the file has to open, upload or print somewhere else. WebP opens in all current browsers; older Photoshop and Windows Photo versions cannot open it, while PS does not open in browsers; Ghostscript, Okular and Evince open it, and so did macOS Preview before Ventura.

About WebP and PS files
What is a WebP file?
WebP can be lossy or lossless and still keep transparency, and at the same visual quality it usually lands 25 to 35 percent smaller than JPG. It is the reason so many images saved from websites turn out not to be JPGs.
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.
WebP to PS not working? Common problems
- "Files up to 25 MB can be converted." Server conversions have a size limit. Save the image at a smaller size first.
- "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.
- "This file is not really in WebP format." The converter checks every file before it runs anything, so a file of another format renamed to .webp is refused. Choose the page for its real format.
Convert WebP to PS from the command line
ImageMagick does the same on your own computer:
magick input.webp -background white -flatten output.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.
WebP to PS converter FAQ
Will I lose quality converting WebP to PS?
No. PS is stored losslessly, so every pixel of the WebP is kept.
Why is the PS a different size from the WebP?
Often larger than the WebP, because the pixels are stored in the PS without lossy compression, and PS adds its own page description around them.
Are my WebP files uploaded?
Yes, for this conversion. A faithful WebP to PS conversion needs ImageMagick, the open-source image toolkit, 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 PS as soon as the result has been sent back to you. We do not keep, read or share it.
Can I convert several WebP files to PS 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 PS file?
PS does not open in browsers; Ghostscript, Okular and Evince open it, and so did macOS Preview before Ventura. PS is common for print jobs, printer drivers and output from Unix, LaTeX and scientific programs.
Is this WebP to PS 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 WebP to PS 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 PS is saved to your Downloads folder.
