PDF Merger FAQ
- How many PDFs can I merge at once?
- You can merge up to 5 PDFs at once, each up to 100 MB. The merged output is a single standard PDF file.
- Can I reorder the PDFs before merging?
- Yes. After uploading, drag and drop PDFs in the file list to set the order. Pages from each PDF are added in the sequence you choose.
- Does merging change the content or quality of my PDFs?
- No. Pages are copied exactly as they appear in the original files — fonts, images, vectors, and formatting are all preserved.
- Are my PDFs uploaded to a server?
- No. The merge is performed entirely in your browser using pdf-lib. Your files never leave your device.
- Can I merge password-protected PDFs?
- Not currently. If a PDF is encrypted or password-protected, you'll need to remove the protection first using another tool before merging.
