Smart document tools

Extraction, checking and question-answering for when converting a file is not enough.

Combining PDFs is the fix for documents that arrive in pieces — a signed page here, an appendix there, three scans from a phone. Doclium joins them into a single file in the order you choose, leaving the page content exactly as it was.

🔒 Never used for AI training: delete a document and it is gone from the server.
⚡ No watermarks: on any tool, including the free tier.
↩ Undo: step back through your last 10 edits.

How to merge PDF files

  1. 1Upload the PDFs you want to combine, or drag them onto the page.
  2. 2Put them in the order you want them to appear.
  3. 3Merge, then download the single combined PDF.

Questions people ask

Is there a limit on how many PDFs I can merge?

You can merge as many as fit your storage allowance. Each file can be up to 50MB.

Does merging reduce quality?

No. Pages are copied across as they are, so text stays selectable and images keep their original resolution.

Can I change the page order?

Yes. The order you select the documents in becomes the order of the merged file.
