"Merge these PDFs into one file"Frequently Asked Questions
Is there a limit on how many files I can merge?
No file-count limit. The combined total just needs to stay within 100 MB — for reference, that's typically 20-30 average-sized PDFs.
Can I rearrange pages across files?
Describe the order in your prompt. For example: "Put the cover page from file A first, then all pages from file B, then pages 3-5 from file C." You can mix and match any way you like.
Do bookmarks carry over?
Bookmarks from each source PDF appear in the final document under their original hierarchy. If two files both have bookmarks, they're listed sequentially in the merged file's sidebar.
What if my PDFs have different page sizes?
Each page retains its own dimensions and orientation. Letter, A4, legal, and landscape pages can all coexist in the merged output.
Can I do this from my phone?
DocuHub runs in any modern browser, including Safari on iPhone and Chrome on Android. Upload files from your phone's storage, iCloud, or Google Drive.
Is there a file-count fee?
No fee regardless of how many files you merge. There's no watermark on the output and no account required — just upload and download.
