Convert PPTX to WebP
Updated Jul 2026
PPTX is a PowerPoint presentation, a deck of editable slides. WebP is a compact image format built for the web. To convert PPTX to WebP, open the file in a converter and export each slide as its own WebP image. Doing this on your own computer keeps the deck, and anything sensitive in it, off other people's servers.

How to convert PPTX to WebP
- Open Morphjet and drag in the PPTX file you want to convert, or a whole folder of decks.
- Choose WebP as the output format, and set a quality level if you want smaller images.
- Convert. Each slide is written out as its own WebP file, saved next to the original, and nothing leaves your machine.
PPTX vs WebP: what actually changes
| PPTX | WebP | |
|---|---|---|
| File type | Editable slide deck | Static image, one per slide |
| File size | Larger, especially with embedded video or fonts | Much smaller, especially at web resolution |
| Editable text and layout | Yes, fully editable | No, flattened into pixels |
| Opens everywhere | No, needs a presentation app that supports it | Yes, opens in any browser or image viewer |
| Animations and transitions | Yes, supported | No, only the static slide is kept |
| Transparency | No, slides have solid backgrounds | Supported by the format, though most slide exports stay opaque |
When to convert, and when not to
Convert PPTX to WebP when you want to drop a slide into a webpage, blog post, or chat without asking the other person to open the whole deck, or when you need a lightweight thumbnail or social preview of a presentation.
Keep the PPTX original if you still need to edit the slides, present them live, or keep the speaker notes and animations, because none of that survives in a flattened image.
Why not just use an online converter?
Slide decks often hold things you would not want sitting on someone else's server, unreleased numbers, client details, internal roadmaps. An online converter has to upload the whole file to turn it into images, even if you only need one slide. Converting on your own computer means the deck, and everything in it, never leaves your machine.
Questions
Does converting PPTX to WebP lose quality?
Each slide is rendered as a lossy WebP image, so there's a small quality trade-off, though at a normal export resolution text and graphics still look sharp on screen.
Does it convert the whole deck or just one slide?
Morphjet turns every slide into its own WebP file, so a twenty-slide deck produces twenty images. You can then keep just the ones you actually need.
Will animations or speaker notes carry over?
No. WebP is a static image format, so transitions, animations, and speaker notes are dropped. Only what's visible on each slide is kept.
Why export slides as WebP instead of JPG or PNG?
WebP files tend to be noticeably smaller than JPG or PNG at similar visual quality, which matters if you're embedding several slide images on a webpage or in an email.
Can I convert a PPTX to WebP without uploading it anywhere?
Yes. Morphjet does the conversion locally on your own computer, so the presentation never travels over the internet.
Morphjet converts PPTX, WebP, and 1,800+ other formats, all on your machine. Launching this July.
