Free online PPS to WEBP converter

A PPS file is a PowerPoint slide show, while web pages and apps commonly use WebP images instead of presentation files. Converting renders selected slides as images for embedding or sharing, but removes editable slide objects.

What the PPS format is

PPS is the PowerPoint Slide Show format, used for presentations that open directly in slide-show mode. Microsoft PowerPoint and LibreOffice Impress can create or open PPS files; the format stores slides with text, shapes, images, and other presentation content.

What the WEBP format is

WebP is a raster image format used mainly for web graphics. It supports lossy and lossless compression, transparency, and animation. A converted slide is typically a separate static image, useful where an image is accepted but a presentation file is not.

How to convert PPS to WEBP

Online on 101convert.com

1. Upload the PPS file to the converter on this page. You can convert several files in one batch; the per-file size limit is shown on the page.
2. Before converting, set any needed options: pages, resolution, quality, image size, max width, max height, auto orient, or strip metadata.
3. Convert the file and download the resulting WebP image files. The conversion runs on the server with LibreOffice, then ImageMagick.

Offline with desktop software

LibreOffice Impress and ImageMagick are free, open-source programs available for Windows, macOS, and Linux. First export the PPS to PDF with Impress using File → Export As → Export as PDF. Then render the PDF pages as WebP images with ImageMagick 7:

magick -density 150 deck.pdf -quality 85 slide-%03d.webp

Replace deck.pdf with the exported PDF filename. The command creates numbered images, one per page; increase or decrease -density to change rendered dimensions and adjust -quality to trade lossy image quality against file size. ImageMagick must have PDF reading support enabled, which may require Ghostscript; a security policy can also block PDF input.

Quality and limitations

Slides contain text and vector elements that become pixels in WebP, so the output is no longer editable as a presentation and can look soft when enlarged beyond its rendered resolution. Increase resolution for small text or print-sized output; use lower quality only when smaller files matter more than fine detail. If the source has many slides, select only the needed pages to avoid producing unnecessary images.
