Free online PPT to WEBP converter

Source format

PPT is the classic Microsoft PowerPoint presentation format used for slide decks created in older versions of PowerPoint. It is widely used in business, education, training, and sales for presentations that may contain text, images, charts, animations, and speaker notes. A PPT file is a multi-slide document, so converting it usually means exporting each slide as an image or turning the presentation into a sequence of images.

Target format

WebP is a modern image format developed by Google. It supports lossy and lossless compression, transparency, and good image quality at relatively small file sizes. WebP is commonly used on websites, in web apps, and for sharing images where smaller files are important. When converting from PPT, WebP is typically used to save each slide as a compact image for web publishing or preview purposes.

How to perform the conversion

The most reliable way to convert PPT to WebP is to first export the slides to images and then save those images as WebP. If you only need a few slides, you can do this manually in presentation software. If you need batch conversion, use a desktop tool or the built-in converter on 101convert.com, where you can convert the file online for free without installing any software.

Method 1: Using Microsoft PowerPoint

1. Open the .ppt file in PowerPoint.
2. Go to File → Save As or File → Export.
3. Choose an image-based export option such as PNG or JPEG.
4. Save the slides. PowerPoint will usually create one image per slide in a folder.
5. Open the exported slide images in an image editor that supports WebP, such as Photoshop, GIMP, or IrfanView.
6. Export or save each image as .webp.

Method 2: Using LibreOffice Impress

1. Open the .ppt file in LibreOffice Impress.
2. Choose File → Export As → Export as Image if available, or export the presentation as PNG images.
3. Convert the resulting images to WebP in an editor or batch tool that supports WebP output.

Method 3: Using command-line tools

If you already have slide images, you can convert them to WebP with tools such as ImageMagick or libwebp. For example, after exporting slides to PNG, run magick slide1.png slide1.webp or use a batch script to process all images. This is useful when you need many slides converted consistently.

Method 4: Using 101convert.com

1. Upload the .ppt file to the converter on 101convert.com.
2. Select WebP as the output format if prompted.
3. Start the conversion and download the resulting files.

Notes on quality and limitations

PPT to WebP is not a true document-to-image one-step conversion in most workflows. Because PPT is a multi-page presentation and WebP is a single-image format, each slide is usually converted separately. This means the result is often a set of WebP images, not one combined file.

Text, vector shapes, and animations in the original presentation will be flattened into pixels. For best quality, export slides at a high resolution before converting to WebP. If the presentation contains small text, charts, or detailed diagrams, use a larger export size to avoid blur. Also note that WebP is excellent for web use, but it is still an image format, so it cannot preserve editable slide content, transitions, or speaker notes.

If you need the presentation content to remain editable, keep the original .ppt file or convert it to a presentation format such as .pptx instead of WebP.
