JPEG vs WebP for PowerPoint Presentations

Updated March 3, 2026 · 7 min read

WebP is newer than JPEG and often smaller, but compatibility still matters. Slide decks balloon quickly when full-resolution photos are dropped in, which makes them slow to open and hard to share.

Recommended settings for PowerPoint presentations

SettingStarting point
FormatJPEG (WebP where accepted)
Widthabout 1920 px on the long edge
Quality78
File size300 KB or less

These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.

JPEG vs WebP

At the same visual quality, WebP files are frequently 25 to 35 percent smaller than JPEG. That makes WebP attractive for websites you control.

For PowerPoint presentations, check whether WebP is accepted. Many forms, portals and older apps still expect JPEG. When in doubt, JPEG is the safe choice; when you control the page, WebP is a free speed upgrade.
