How do I compress a PPTX to 10 MB?

Drop the PPTX onto the compressor above. The 10 MB target is already set, so just click Compress and download the result.

Will the file be exactly 10 MB?

It aims to land at or just under 10 MB. 10 MB here means 10,000,000 bytes, so it also fits sites that count 1 MB as 1,048,576 bytes.

How much quality will I lose at 10 MB?

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.

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.

What is 10 MB typically needed for?

Common reasons: very image-heavy presentations; files that bounced as email attachments; sending through chat apps instead of a download link. Limits vary by site, so check the exact number where you're uploading.

Yes. It's processed in an isolated cloud sandbox for your job only and 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.
