## How to compress a PPTX to 10 MB

1. **Add your PPTX.** Drop one or more PPTX files onto the compressor above, paste them, or click to browse.
2. **10 MB is preset.** The target is already set to 10 MB, and each file is compressed to land at or just under it. You can switch to another size or a percentage to reduce by.
3. **Compress.** Click Compress. The PPTX is processed in an isolated cloud sandbox and deleted afterwards.
4. **Check and download.** Check the new size, then download each file or all of them as a ZIP.

## Good to know

- 10 MB is for genuinely big files; images keep quality close to the original.
- 10 MB holds roughly 33–66 photos at on-screen quality plus all the text. Text, styles and layout are left exactly as they are; only the presentation's images change.
- 10 MB here means 10,000,000 bytes, a little under the 10,485,760 bytes some sites mean by 10 MB, so the result fits either way.
- PPTX files are compressed in an isolated cloud sandbox created just for your job; the upload and the result are deleted automatically afterwards.

## What fits in 10 MB

Embedded images take up nearly all the space in a presentation; the text and structure are tiny by comparison.

| Content | Roughly fits | Notes |
| --- | --- | --- |
| Text-only presentation | Easily | Text is already compressed |
| Photos at on-screen quality | About 33–66 photos | Each recompressed to roughly 150–300 KB |
| Screenshots and diagrams | About 66–132 images | Flat graphics compress well |

_Rough guide. How many images fit depends on their dimensions and detail._

## What 10 MB is typically for

- Very image-heavy presentations
- Files that bounced as email attachments
- Sending through chat apps instead of a download link

Limits vary by site and change over time; check the exact number where you're uploading.

## How PPTX gets smaller

Shrinks the embedded photos and repacks the document at maximum compression; text and layout are untouched.

### My PPTX is already smaller than 10 MB. What now?

Then it already fits, and compressing it further would only cost quality. Upload it as it is, or pick a smaller target if you need it smaller still.

### What if my PPTX can't get down to 10 MB?

If a presentation is mostly images, 10 MB may force them very small. Remove images you don't need, or pick a larger size.
