PPTX to PNG Converter

What happens when you convert PPTX to PNG

• The PPTX is opened by LibreOffice, the open-source office suite, on our conversion server, laid out exactly as it would print, and each slide is then drawn as an image by MuPDF at 150 dpi, the resolution most documents are printed at.
• A one-page PPTX gives a single PNG; a longer one comes back as a ZIP file with one PNG per page, named page-01.png, page-02.png and so on, for up to 100 pages.
• At 150 dpi, a 16:9 slide becomes 2000 by 1125 pixels and a 4:3 slide 1500 by 1125. The longest side is capped at 6,000 pixels.
• PNG is lossless, so text and lines stay exactly as crisp as the page rendered them.
• Each image shows the slide in its final state, with every animated item visible. Hidden slides are skipped, and speaker notes are not included.
• 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 PNG online

1. 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.
2. There are no settings to choose: the converter keeps everything the target format can hold.
3. Press "Convert to PNG". 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.
4. Save each PNG with its download button. Our server has already deleted both your PPTX and the PNG by then.

Why convert PPTX to PNG?

PPTX files usually come from presentations for work, school and conferences. People convert them to PNG to share a slide as a picture: in a chat or a social post, on a website, in a presentation, or in an upload form that only accepts images. PNG opens on every phone and computer without an office program.

How to convert PPTX to PNG on Windows, Mac, iPhone and Android

On Windows

Open this page in Chrome, Edge or Firefox, drag your PPTX files in from File Explorer, and press Convert. Each PNG is saved to your Downloads folder.

On a Mac

Safari, Chrome and Firefox all work. Drag the PPTX files from Finder onto the drop zone and the PNG files land in Downloads.

Best settings for PPTX to PNG

There are no settings: every slide is rendered at 150 dpi, the longest side is capped at 6,000 pixels, and at most the first 100 slides are converted.

To get one slide only, save just that slide as its own file first, or pick the image you want out of the ZIP. For a document you will print or send, PDF keeps the text sharp at any size and selectable.

PPTX vs PNG: the differences

About PPTX and PNG 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 a PNG file?

PNG compresses without losing a single pixel, so screenshots and text stay razor sharp, but a photograph saved as PNG is often three to five times the size of the same photo as JPG.

PPTX to PNG 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 PNG from the command line

LibreOffice and Poppler do the same on your own computer: the first command makes a PDF, the second writes one image per slide.

soffice --headless --convert-to pdf input.pptx
pdftoppm -r 150 -png input.pdf page

Converting 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.
