PPT to WebP Converter

Convert PPT to WebP Online

Rasterize a legacy PowerPoint presentation (.ppt, the binary format from PowerPoint 97-2003) into WebP images — each slide is rendered to a flat picture you can drop straight into a web page, a blog post, or a thumbnail strip. WebP keeps those slide stills compact for the web: it does both lossy and lossless compression and supports transparency, so a title slide can stay crisp while a photo-heavy slide compresses small. A multi-slide deck comes back as one WebP per slide, so you can publish or reuse them one at a time.

How to Convert PPT to WebP

1. Upload Your PPT File: Drag and drop your .ppt onto the page or click "+ Add Files". Add several decks and they convert with the same settings.
2. Set Lossless?: Leave it on "No" for small lossy files (best for photo-heavy slides), or switch to "Yes" to keep text and sharp diagram edges crisp.
3. Pick Quality Preset and Image Resolution: "Very High" is the default; raise the render DPI or set a Width/Height if you need larger, print-sharp slides.
4. Convert and Download: Click Convert. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared. Download each WebP individually or grab them all as a ZIP.

Lossy vs Lossless WebP for Slides

WebP can encode each slide two ways. Lossy throws away some detail for the smallest file; lossless reproduces every pixel exactly. The right pick depends on what is on the slide.

Frequently Asked Questions

Does a multi-slide PPT become one WebP or many?

Each slide is rasterized to its own WebP, so a 12-slide deck returns 12 separate WebP images. You can download them one at a time or as a single ZIP. WebP itself holds one still image per file — it is not a multi-page container — which is why slides come out as individual pictures rather than one stacked file.

Will the text in my slides still be selectable after converting to WebP?

No. Converting to WebP flattens each slide into a picture, so the text becomes pixels — it is no longer selectable, searchable, or editable, and animations, transitions, and speaker notes are dropped. If you need selectable text or a single shareable file, convert to PPT to PDF instead, which keeps every slide as a real page with live text.

Should I use lossless for slides with a lot of text?

Yes. Set Lossless? to "Yes" for slides built from text, tables, charts, or line art — lossless WebP keeps the edges crisp, whereas lossy compression can put faint halos around small type at lower quality settings. For photo-heavy slides, lossy stays the better trade because it produces a much smaller file with no visible loss.

How much smaller is WebP than PNG or JPEG?

Per Google's measurements, lossless WebP images are about 26% smaller than equivalent PNGs, and lossy WebP images are 25-34% smaller than comparable JPEGs at the same SSIM quality. In our testing, a typical 1080p text-and-chart slide exported as lossless WebP landed clearly under the same slide saved as PNG, with no visible change to the type.

Why is my .ppt different from a .pptx file?

.ppt is the legacy binary PowerPoint format (PowerPoint 97-2003), stored as an OLE2 compound document. .pptx, introduced with PowerPoint 2007, is an Office Open XML file — really a ZIP of XML parts. This page accepts the older .ppt; the rasterized WebP output looks the same regardless of which format the deck started in. To turn a modern deck into WebP, use PPTX to WebP.

Do all browsers display WebP slides?

WebP is supported in current Chrome, Firefox, Edge, and Safari (Safari 14.1 and later, i.e. macOS Big Sur / iOS 14 onward). For a still image you also want to print or edit, PPT to PNG or PPT to JPG give you more universally accepted files at the cost of a larger size than WebP.
