Step 1
Drop or choose one or more .webp images — the order becomes the slide order
Convert WebP to PowerPoint
Half the web now serves WebP images, yet PowerPoint still refuses them. This tool fixes that head-on: drop in WebP files and each is losslessly transcoded to PNG and placed on its own 16:9 slide, ready for any version of PowerPoint. The whole conversion runs in your browser.
Drag your file here, or browse
Your WebP images are assembled into a single 16:9 PPTX locally in your browser — one slide per image, scaled and centered. Nothing is uploaded.
Losslessly transcoded to PNG — desktop PowerPoint cannot display WebP; the transcode opens everywhere.

The Complete Guide to WebP to PPT Conversion
What this tool does
Right-click-save an image from the web today and odds are you get a .webp — small and web-friendly, but drag it into PowerPoint and you get a broken picture, because desktop Office still does not support the format. This tool losslessly transcodes each WebP to PNG in your browser, then places it on its own 16:9 slide. Compatibility problem, solved once.
How to use it
- Drop in imagesMulti-select is supported; the order you add is the slide order.
- Click convertEach WebP is losslessly transcoded to PNG and placed on a 16:9 slide.
- Download the PPTXOpens in any version of PowerPoint or WPS.
Specs & limits
- Input
- .webp
- Output
- .pptx (16:9)
- Batch
- multiple files
- Transcode
- lossless PNG
- Transparency
- preserved
- Processing
- local, in-browser
The transcode is pixel-for-pixel lossless: the PNG contains exactly what the WebP did, and transparent backgrounds stay transparent. PNG files are usually larger than WebP — if the finished deck runs large, pass it through the PPT compressor.
Tips for best results
- Use web assets directlyNo more detours through a separate format converter for saved .webp files.
- Animated WebP keeps its first frameAnimation is not carried over — use GIF to PPT if you need motion.
- Compress later if neededAssemble at full quality first, then slim the deck for sharing.

FAQ
WebP to PPT FAQ
These answers explain what the tool does, what files it supports, and where the current limits are.
Are my images uploaded to a server?
No. Both the transcode and the PPTX assembly run entirely in your browser — your images never leave your device.
Why convert to PNG instead of embedding the WebP directly?
Desktop PowerPoint does not render WebP — a directly embedded WebP shows up as a broken picture. PNG is lossless, so the transcode keeps every pixel and any transparency while making the deck open everywhere.
Does the transcode lose quality?
No pixels are altered — PNG is a lossless format, so the slide shows exactly what the WebP contained. PNG files are usually larger than the WebP source, which is normal.
Can I edit the slides afterwards?
Yes. The output is a normal PPTX — reorder slides, add text, or move and resize images in any presentation app.
