FAQ

Q: What if my file is still too large after compression?

A: Try removing embedded videos and linking them instead. Videos are typically the largest contributors to file size. You can also try splitting the presentation into multiple files.

Q: Can I compress a password-protected file?

A: Remove the password protection first, compress the file, then re-add protection if needed. The compression tool cannot process encrypted files.

Q: Why is my compressed file larger than expected?

A: Ensure you’re saving as PPTX format. PPT format creates larger files. Also check that compression was actually applied by reviewing the settings.

Q: Do I need to compress each slide separately?

A: No, compression applies to the entire presentation. However, you can manually optimize individual slides before using the compression tool.

Q: Will my transitions and animations be preserved?

A: Yes, all transitions, animations, and interactive elements are preserved during compression. Only media quality is affected.

Q: How do I compress for mobile viewing?

A: Use lower compression settings: 96 ppi for images and 480p for videos. This creates smaller files that load quickly on mobile devices.
