What happens when you convert PPTX to EPS
- The PPTX is opened by LibreOffice, the open-source office suite, on our conversion server and exported to PDF, and Ghostscript, the standard PostScript interpreter, writes the first slide as an EPS.
- An EPS holds exactly one page by definition, so only the first slide is converted. To convert another slide, move it to the front or save it as its own presentation first.
- Text, shapes and charts stay vectors in the EPS, so it scales to any size for print. Photos on the slide are embedded as they are.
- Where the file uses a font our server does not have, a metric-compatible one is used instead: Carlito for Calibri, Caladea for Cambria and Liberation fonts for Arial, Times New Roman and Courier New, so lines break where they did. Unusual or decorative fonts may look different.
- 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 PPTX to EPS online
- Press "Choose PPTX 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 EPS". 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 EPS with its download button. Our server has already deleted both your PPTX and the EPS by then.
Why convert PPTX to EPS?
PPTX files usually come from presentations for work, school and conferences. People convert them to EPS because EPS is what many printers, sign makers and older design software still ask for when you send artwork.
In short, PPTX is good at what it was made for, and EPS is the more practical choice when the file has to open, upload or print somewhere else. PPTX opens in PowerPoint, Google Slides, Keynote and LibreOffice Impress, while EPS does not open in browsers; Illustrator, Inkscape and Affinity Designer open it, and macOS Preview converts it to PDF.

About PPTX and EPS files
What is a PPTX file?
PPTX has been PowerPoint's default format since 2007. Like DOCX it is a ZIP of XML files, one per slide, plus the media used in them.
What is an EPS file?
An EPS is a small PostScript program that draws one page of artwork, with a bounding box so it can be placed inside other documents. Printers and designers still ask for it, but it is gradually being replaced by PDF and SVG.
PPTX to EPS 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 file will not convert. It may be password protected, damaged, or saved in a newer or unusual version of the format.
Convert PPTX to EPS from the command line
LibreOffice and Ghostscript do the same on your own computer:
soffice --headless --convert-to pdf input.pptx
gs -dSAFER -dBATCH -dNOPAUSE -sDEVICE=eps2write -dFirstPage=1 -dLastPage=1 -sOutputFile=output.eps input.pdfConverting 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.
PPTX to EPS converter FAQ
Will I lose quality converting PPTX to EPS?
Vector content, text included, stays vector, so the EPS is sharp at any size. Only the first slide is kept.
Why is the EPS a different size from the PPTX?
The EPS holds one slide, but PostScript describes it as text and embeds its fonts and pictures, so it can be larger than the whole PPTX.
Are my PPTX files uploaded?
Yes, for this conversion. A faithful PPTX to EPS conversion needs LibreOffice and Ghostscript, two 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 EPS as soon as the result has been sent back to you. We do not keep, read or share it.
Can I convert several PPTX files to EPS 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 an EPS file?
EPS does not open in browsers; Illustrator, Inkscape and Affinity Designer open it, and macOS Preview converts it to PDF. EPS is common for logos and artwork for print, and stock vector graphics.
Is this PPTX to EPS 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 PPTX to EPS 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 EPS is saved to your Downloads folder.
