Is there a limit on how many PDF files or pages I can combine?

You can upload up to five PDF documents simultaneously in a single session without registration. There is no strict restriction on total page counts, provided the combined file size stays within browser memory limits. Larger documents process smoothly through our stream compiler.

Are my uploaded PDF documents kept private and secure?

Every file transmission is protected using strict 256-bit TLS encryption. Uploaded documents are processed in isolated memory buffers and automatically purged from our servers within fifteen minutes of job completion. We never inspect, store, or share your document contents.

Does merging PDFs reduce font sharpness or image quality?

No, merging preserves original vector lines, embedded fonts, and raster images exactly as created in the source files. The compiler rebuilds the internal PDF catalog without recompressing underlying graphic elements. Your final document maintains full fidelity for high-resolution printing.

Can I combine PDF files on a smartphone without installing an app?

Yes, our PDF merger runs completely inside modern mobile browsers on both iOS and Android. You can choose documents stored in iCloud, Google Drive, or local device storage and combine them on the go. No app installation or account login is required.
