Frequently Asked Questions
Q: What file formats does PPT Compressor support?
PPT Compressor supports both .ppt and .pptx PowerPoint file formats. It works with presentations created in Microsoft PowerPoint, Apple Keynote (exported as PowerPoint), Google Slides (downloaded as PowerPoint), and other compatible software.
Q: Where are my compressed files saved?
Compressed files are automatically saved to your Downloads folder with "_compressed" added to the original filename. For example, "presentation.pptx" becomes "presentation_compressed.pptx". After compression, Finder will automatically open to show you the file.
Q: What's the difference between Balanced and Strong compression?
Balanced: Provides good compression (typically 50-70% size reduction) while maintaining high quality. Best for presentations that will be displayed on large screens.
Strong: Maximum compression (up to 90% size reduction) with slightly more aggressive optimization. Perfect for email attachments and file sharing.
Q: Will compression affect my animations and transitions?
No, all animations, transitions, and slide timings are preserved perfectly. PPT Compressor only optimizes media files (images and videos) within your presentation. The presentation structure, formatting, and effects remain unchanged.
Q: Is there a file size limit?
No, PPT Compressor can handle presentations of any size. Since all processing happens locally on your Mac, there are no upload limits or restrictions. The app has been tested with presentations over 1GB in size.
Q: Does PPT Compressor require an internet connection?
No, PPT Compressor works completely offline. All compression happens locally on your Mac, ensuring your files remain private and secure. No data is ever uploaded to any server.
Q: Can I compress multiple presentations at once?
Currently, PPT Compressor processes one presentation at a time for optimal performance. However, the compression is very fast (usually under 30 seconds), so you can quickly process multiple files in sequence.
