A: No. All stream parsing and image quantization occur strictly inside your browser. No files or telemetry ever leave your device. Q: How to make a pdf smaller without losing text readability? A: The extension uses selective stream recompression. It compresses embedded background images while keeping native text and vector fonts razor-sharp. Q: Can this pdf size reducer handle heavy books and scanned documents? A: Yes. Because the engine processes streams in a lightweight background worker, it smoothly handles 1,000+ page contracts without freezing your browser. Q: Why did my file size not decrease?
