How many PDF files can I merge at once?

There is no hard limit on the number of files you can merge. Each individual file can be up to 20 MB. Very large batches may take longer to process.

Will the quality of my PDFs be affected?

No. The merge operation does not re-encode, compress, or modify any content. All pages are copied exactly as they appear in the original files.

Can I merge password-protected PDFs?

No, password-protected PDFs cannot be merged. Remove the password protection first using your PDF reader, then merge the files.

Does the page order matter?

Yes. Pages are combined in the exact order shown in the file list. Use the arrow buttons to rearrange files before merging.

Can I merge PDFs that have different page sizes?

Yes. Each page keeps its own original size — merging doesn't force every page to match a common dimension, so a merged file can mix A4, Letter, or any other page size without distortion.
