Frequently Asked Questions
Common questions about combining and organizing PDF files.
Are my sensitive documents uploaded to an external server?
No. The entire merge process takes place 100% locally in your web browser using WebAssembly and client-side JavaScript. Your confidential contracts, financial statements, and personal records are never transmitted across the network or stored on remote servers.
Can I reorder the files before merging?
Yes. You can drag and drop file cards directly to place them in your preferred sequence, or use the arrow buttons ( / ) on each file card. Quick sort buttons (A-Z, Z-A, and Reverse) are also available.
Does merging PDFs reduce image resolution or vector sharpness?
No. The merge process is completely lossless. The engine copies the underlying PDF page dictionaries, typography, hyperlinks, and image raster streams directly into a unified document without applying lossy compression.
Can I merge password-protected PDF files?
If one of your files requires an open password, please decrypt it first using our Unlock PDF tool. Once unlocked, you can freely merge it with your other documents.
Is there a file limit or fee for combining PDFs?
No. The tool is 100% free with zero registration, subscription barriers, or daily caps. You can merge as many documents as your local device's browser memory can handle.
