Frequently Asked Questions
How do I use the PDF Compressor?
It's simple! Just upload your PDF file using the upload box, select a compression level from the options panel, and click the 'Compress PDF' button. Your smaller PDF will be ready to download in moments.
What's the difference between the compression levels?
'Low Compression' gives you the smallest file size, perfect for web use. 'Recommended' offers a great balance of size and quality. 'High Quality' is best for printing, and 'Maximum Quality' preserves the most detail for professional use.
Is it secure to upload my files?
Absolutely. We use SSL encryption for all transfers. Your files are automatically and permanently deleted from our servers one hour after processing. We never share your files or their content.
Will compressing the PDF reduce its quality?
Compression always involves a trade-off between file size and quality. However, our tool is optimized to reduce the file size as much as possible while keeping the quality high. For most documents, the quality difference is barely noticeable.
Is there a limit to the file size I can upload?
We support files up to a generous size limit suitable for most needs. If you have an extremely large file, the compression process might take a bit longer.
Can I use this tool on my Mac, Windows, or mobile device?
Yes! Our PDF compressor is a web-based tool, which means it works on all operating systems and modern browsers, including on your phone and tablet.
