Convert PowerPoint to PNG
Ethical Tube's free PowerPoint to PNG converter saves every page of a PowerPoint presentation as a PNG image, using LibreOffice, the open-source office suite. It runs entirely in your browser, so your presentations are never uploaded, and it's free with no sign-up or watermark. The first conversion downloads the LibreOffice engine (77 MB) once, and it's cached after that.
Files are converted on your device and never uploaded.

The formats
PowerPoint and PNG at a glance
What is a PowerPoint file?
PPTX is the presentation format PowerPoint has used since 2007. It holds slides with text, images, charts, animations, transitions, and speaker notes. It opens in Microsoft PowerPoint, Google Slides, Apple Keynote, LibreOffice Impress, and WPS Office.
What is a PNG file?
PNG is a lossless image format, so it keeps every pixel exactly as it was saved. It supports transparent backgrounds, which makes it the usual choice for logos, screenshots, and graphics with sharp edges or text. A photo saved as PNG is often several times larger than the same photo as a JPG. It opens in every web browser, Windows Photos, macOS Preview, iPhone and Android galleries, and editors like Photoshop, GIMP, and Figma.
Good to know
What changes when you convert PowerPoint to PNG
- Each slide becomes one PNG image. Several images download as a ZIP file.
- Text in the images can't be edited or selected.
- The first conversion downloads LibreOffice compiled to WebAssembly (77 MB). It's cached, so later visits start quickly.
- Chinese, Japanese, and Korean text may appear in a fallback font.
- Password-protected documents can't be converted.
- It works best on a computer, because LibreOffice needs a lot of memory.
FAQ
Questions, answered
Is this PowerPoint to PNG converter free?
Yes. It's completely free, with no sign-up, no watermark, and no limit on how many files you convert. It costs Ethical Tube nothing to run, because the conversion happens on your own device rather than on a server.
Are my files uploaded anywhere?
No. The conversion runs inside your browser with LibreOffice compiled to WebAssembly, so your files never leave your device. Once the page and the engine have loaded, it even works offline.
Why is there a download the first time?
The conversion uses LibreOffice, the open-source office suite, compiled to run inside your browser. It's about 77 MB, downloads once from Ethical Tube's own server, and is cached for next time. Your documents are never uploaded.
Can I convert several PowerPoint files at once?
Yes. Add as many as you like. They're converted one after another, and you can download each PNG file as soon as it's ready or all of them in one ZIP file.
Does it work on iPhone, Android, Mac, and Windows?
It works in Chrome, Edge, Firefox, and Safari, but it's built for computers. LibreOffice needs about 1 GB of memory, which many phones can't spare.
What can open a PNG file?
Every web browser, Windows Photos, macOS Preview, iPhone and Android galleries, and editors like Photoshop, GIMP, and Figma.
Is there a file size limit?
There's no upload limit because nothing is uploaded. The practical limit is your device's memory: everyday files are fine, and most computers handle documents with hundreds of pages.
