Frequently Asked Questions
How many PDF files can I merge at once?
You can merge up to 20 PDFs in a single session with a combined size of up to 200MB — plenty for most use cases like merging reports or compiled invoices.
Can I reorder pages before merging?
Yes. After uploading your PDFs, you can drag and drop files to rearrange their order before clicking Merge.
Will bookmarks and links inside the PDFs be preserved?
Internal hyperlinks within PDFs are preserved. External bookmarks may vary depending on the PDF structure.
Does merging PDFs reduce quality?
No. Merging is purely structural — it combines pages without re-processing or re-encoding any content, so there is zero quality loss.
