❓ FAQ
Frequently Asked Questions
Our compressor uses intelligent image optimization, DPI reduction, and JPEG quality adjustment to reduce file size while preserving visual quality. Each page is rendered at your chosen DPI and recompressed as an optimized image, significantly reducing file size for image-heavy PDFs while keeping text crisp and readable.
Yes, absolutely. All PDF compression happens entirely in your browser using JavaScript. Your files are never uploaded to any server. Everything is processed locally on your device, ensuring complete privacy and security.
We offer four compression levels: Low (~20% reduction, highest quality), Recommended (~50% reduction, balanced), High (~75% reduction, small files), and Maximum (~90% reduction, smallest size). You can also fine-tune with custom DPI (48-300) and image quality (10-100%) settings.
Yes, our tool supports batch compression. Simply drag and drop multiple PDF files or use the "Add More Files" button to queue additional files. All files will be compressed with your chosen settings.
Each PDF file can be up to 100MB. Since all processing happens in your browser, larger files may take more time depending on your device's processing power and available memory.
The compression process renders pages as optimized images, so text within the PDF may not be selectable or searchable after compression. For text-heavy documents where searchability is important, we recommend using the "Low" compression level for minimal quality impact.
