What to expect
Original page dimensions and orientation are retained when pages are copied.
Encrypted or damaged PDFs may require repair or a password before they can be combined.
Quality and file behaviour
- Pages are copied without rasterising them, so existing vector content remains intact.
- Existing page transparency and drawing commands are preserved by page copying.
- The PDF structure is rewritten, but page artwork is not intentionally recompressed.
Common problems
- Password-protected, structurally damaged or memory-heavy documents may not open.
Frequently asked questions
Are the PDFs uploaded while they are combined?
No. The browser reads and combines the selected PDFs on this device, then creates a local download.
Will different page sizes be changed?
No. Each copied page keeps its own dimensions, so mixed portrait, landscape and custom pages remain mixed.
