Combine multiple PDF files in any order — reorder, rotate, pick page ranges, and add page numbers. Runs entirely in your browser.
Merge PDF Features
- 100% private — Files are merged inside your browser using pdf-lib. Nothing is uploaded — we literally cannot see your documents.
- Reorder & rotate — Move files up or down with one click and rotate any document 90° at a time before merging.
- Pick page ranges — Combine just the pages you need — type "1-3, 5" to skip the rest, or leave it as "all".
- Optional page numbers — Toggle page numbers on the merged output to keep things clean for printing or sharing.

Frequently Asked Questions
How many PDFs can I merge at once?
There is no hard cap. The tool comfortably handles 20+ PDFs at a time — performance only depends on your device's memory. Most laptops and phones from the last 5 years can merge a 50-file batch in under 10 seconds.
Are my PDFs uploaded to a server?
No. Every merge runs entirely in your browser using the pdf-lib library — your files never reach our servers, never appear in any log, and are gone the moment you close the tab. Safe for confidential files like bank statements, Aadhaar, PAN, or contracts.
Can I pick specific pages from each PDF?
Yes. Each file in the list has a "Page range" field. Type something like "1-3, 5, 7-9" to merge only pages 1, 2, 3, 5, 7, 8, 9 from that document. Leave it as "all" to include every page.
Will the merged PDF lose any quality?
No. Merging copies the original page bytes — text, images, fonts, hyperlinks, and form fields are preserved exactly as they were. There is no recompression or re-rendering step.
Can I rotate pages before merging?
Yes. Click the rotate icon on any file row to spin it 90° at a time, or use the page editor for finer control. The rotation is baked into the merged output, not just a preview.
Will the file size be much larger after merging?
Usually the merged file is roughly the sum of the inputs. If you need a smaller result, run the merged PDF through our Compress PDF tool — it can typically shave 40–80% without visible quality loss.
Can I add page numbers to the final PDF?
Yes. Tick the "Add page numbers" option before merging. A subtle page number is stamped at the bottom-center of every page in the merged output — handy for printed reports or numbered submissions.
Does this work on phones and tablets?
Yes. The tool is fully responsive and runs in any modern mobile browser (Chrome, Safari, Edge, Firefox). Drag-and-drop is replaced by a tap-to-browse button on touch devices.
