Frequently Asked Questions
How does the PDF compression work?
Our PDF compressor uses advanced algorithms to reduce file size by optimizing images, removing redundant information, and restructuring the document. It can compress images, remove metadata, and optimize fonts while maintaining the visual quality of your document.
Will compression affect the quality of my PDF?
The impact on quality depends on the compression level you choose. Low compression maintains high quality with modest size reduction. Medium compression offers a good balance between quality and file size. High compression provides maximum size reduction but may affect image quality. Text and vector graphics typically remain sharp at all compression levels.
Is there a limit to the file size I can compress?
Since all processing happens in your browser, the file size limit depends on your device's memory. Most modern devices can easily handle PDFs up to 100MB, but performance may vary for very large files.
Can I compress password-protected PDFs?
Currently, our tool cannot process password-protected PDFs. You'll need to remove the password protection from your document before uploading it to our PDF Compressor.
