Compress PDF FAQ
Are my PDF files uploaded to a server?
No. FileNaro compresses your PDF documents entirely inside your browser on your device. Your files never leave your computer.
Will compression always reduce the file size?
Not always. Documents that are already heavily compressed or consist primarily of plain vector text without images may already be near their minimum size.
Does compression affect document quality?
Stronger compression options apply higher image optimization, which may slightly reduce the sharpness of embedded photos and scans to achieve a smaller file size.
Can I preview or check the size reduction before downloading?
Yes. FileNaro shows the exact original size, compressed size, and percentage reduction before you download.
