Frequently asked questions

How many PDFs can I merge at once?

As many as your browser can hold in memory — typically dozens of 10–50 MB files without issue.

Can I reorder pages before merging?

Yes. Drag files into the desired sequence; pages are concatenated in that order.

Does merging re-encode or recompress pages?

No. Original page streams are copied byte-for-byte, so text remains selectable and quality is preserved.
