Frequently asked questions
Does merging PDFs reduce quality?
No. Merge PDF concatenates the original pages byte-for-byte — no re-rendering or recompression, so text stays sharp and vector graphics stay crisp.
Is there a limit on how many PDFs I can merge?
No fixed file-count limit — the only constraint is your plan's total upload size: 10MB as a guest, 25MB signed in, and up to 120MB on a paid pass. Merge as many reports, chapters, or scans as fit in one pass.
Can I reorder pages before merging?
Yes — files merge in the order you upload them. For fine-grained page reordering after merging, run the result through Organize PDF.
Will merging combine forms or signatures correctly?
Yes, form fields and existing signatures in each source PDF are preserved in the merged output.
Can I merge PDFs on a phone or Chromebook?
Yes — it runs in the browser, so there is nothing to install and no desktop app required. The same drag-and-drop ordering works on Android, iOS and ChromeOS as on a laptop.
Can I include Word files or photos in the merge?
Not directly — merging works on PDFs. Convert first with Word to PDF or JPG to PDF, then merge the results. That two-step route is deliberate: it lets you check each conversion looks right before it becomes part of a longer document.
