How Browser-Based Compression Works
Technical Process
File Selection: You select a file from your device using the browser’s file picker or drag-and-drop
Local Reading: The browser reads the file using JavaScript File API - the file stays on your device
Processing: Web Workers process the file in the background, optimizing images and media
Output Generation: The compressed file is created in memory and offered for download
Cleanup: Temporary data is automatically cleared when you close the tab
Privacy Benefits
Since files are processed entirely in your browser:
- No Server Upload: Files never leave your device

FAQ
Q: Is browser-based compression as effective as desktop software?
A: Yes. Modern web technologies enable the same compression algorithms used in desktop software. Our browser-based tool delivers professional-quality results comparable to any desktop application.
Q: Are my files uploaded to a server?
A: No. Our tool processes files entirely in your browser using JavaScript. Your presentations never leave your device, ensuring complete privacy.
Q: Can I use web-based tools without internet?
A: After the initial page load, the tool may work offline for some browsers. However, a stable internet connection ensures the best experience and latest features.
Q: What happens if my browser crashes during compression?
A: Since processing happens in memory, a crash would require restarting the process. However, your original file is never modified, so you can simply reload the page and try again.
Q: Is there a file size limit for browser-based compression?
A: The limit depends on your browser and device memory. Most presentations up to several hundred megabytes process without issues. Very large files may require more RAM.
