What is the PDF Compressor Tool?
The KagazKit PDF Compressor is a powerful online utility that reduces the file size of your PDF documents while maintaining readable quality. Many government portals, university admission forms, and corporate HR systems impose strict upload limits — often as low as 200KB or 500KB. Large scanned documents or multi-page PDFs regularly exceed these limits. Our tool uses industry-standard Ghostscript compression on our secure processing server to dramatically reduce PDF file sizes, making them suitable for any upload portal.

Frequently Asked Questions
Is my PDF stored on your server?
No. While the PDF is temporarily transmitted to our processing server for Ghostscript compression, it is processed entirely in memory and instantly deleted after compression is complete. We never store, inspect, or retain your documents.
How much can the file size be reduced?
Reduction depends on the original PDF content. Scanned image-heavy PDFs typically see 50-80% reduction. Text-heavy PDFs with minimal images may see 20-40% reduction. The tool always shows you the before-and-after sizes so you can evaluate the result.
Will compression affect the readability of my PDF?
The compression algorithm is optimized to maintain readable quality for printed text and standard images. While some quality loss is inherent in compression, the output is designed to be perfectly acceptable for official submissions and document uploads.
What is the maximum file size I can upload?
We recommend files under 10MB for the best experience. This limit prevents browser memory issues, especially on mobile devices and iOS Safari where large files can cause the browser tab to crash.
Can I compress password-protected PDFs?
No, password-protected or encrypted PDFs cannot be processed because the compression engine needs to read and re-render the document contents. Remove the password protection first, then compress the file.
