Common questions about our free PDF resizing tool.
Does this tool make the text blurry? **
No. Our smart compression technology reduces file size by optimizing fonts and images, but keeps the text crisp and legible. Use "Low" or "Medium" compression for best visual results.
Is it safe to compress private bank statements or contracts? **
Yes, completely safe. Unlike other sites, NasajTools processes your files locally in your browser. Your documents are never uploaded to a server, ensuring 100% privacy and security.
Why didn’t my PDF file size decrease? **
If your PDF is already highly optimized or consists mainly of text without large images, further compression may be minimal. In such cases, try the "High Compression" setting.
Is there a file size limit? **
Since the processing happens on your device, there are no strict server upload limits. You can compress large files as long as your device has enough memory.
