How to Compress Images for PowerPoint Presentations on Windows
On Windows, a browser-based compressor avoids installing extra software. 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
| Setting | Starting point |
|---|---|
| Format | JPEG (WebP where accepted) |
| Width | about 1920 px on the long edge |
| Quality | 78 |
| File size | 300 KB or less |
These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.
How to Compress Images
Open Edge, Chrome or Firefox, drag your photos from File Explorer into the drop zone, and set quality around 78.
For several files, use Download all to get a single ZIP. Extract it and your images are ready for PowerPoint presentations with the original files untouched.
Step by step with TheCompressJPEG
- Open the compress JPEG to 300 KB tool, or the main compressor for custom settings.
- Drop in your image. Nothing is uploaded; it is processed in your browser.
- Set the maximum width to 1920 and the target size to 300 KB.
- Press Compress, check the result and download it.
Quick tips
- Check the result on a phone, where most people will see it.
- Use consistent dimensions for a set of related images.
- Resize before you compress; it improves quality at any file size.
- Write a size limit slightly below the stated maximum to leave a margin.

Wrapping up
For PowerPoint presentations, the reliable recipe is simple: resize to around 1920 pixels, compress at quality 78 or to a 300 KB target, and check the result before you upload. Keep the original so you can always start again.
