Frequently Asked Questions

How many PDFs can I merge?
You can merge as many PDF files as your browser's memory allows.
Can I change the order?
Yes, after uploading you can drag files into the order you want.
Can I reorder the PDFs before merging?
Yes — use the up/down arrows next to each file to arrange them in the order you want them to appear in the final PDF.
Is there a limit to how many PDFs I can merge?
There's no limit enforced by the tool itself. Since merging happens in your browser, the practical limit is your device's available memory.
Do bookmarks and links inside the original PDFs survive the merge?
Each page's visible content is copied over exactly as-is. Internal links and bookmarks may not always carry over — check the merged file if your PDFs rely on them.
