Batch Compressing Photos for PowerPoint Presentations
When you have dozens of images, consistency matters as much as size. 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.
Batch Compressing Photos
Drop all the files at once. The same settings are applied to each, so a set of photos for PowerPoint presentations ends up with matching dimensions and similar file sizes.
Use Download all to collect everything in one ZIP. A target of 300 KB per image keeps the whole batch predictable.
Step by step with TheCompressJPEG
- Open the compress JPEG to 300 KB tool, or the main compressor for custom settings.

Quick tips
