When merging makes sense
- Submitting an application with several supporting documents
- Sending an invoice together with receipts
- Combining scanned pages into a single document
- Building one report from sections written by different people
One file means one attachment, a fixed page order and nothing getting lost along the way.
Check these things before you merge
- Order: decide the final sequence first, since it is easier than fixing it afterwards
- Page sizes: mixing A4 and Letter pages works, but pages may look inconsistent when printed
- Passwords: protected files usually need to be unlocked before they can be combined
- Bookmarks and links: these can be lost or broken when files are combined
- File size: the merged file is roughly the sum of the originals
How to merge PDFs in your browser
- Open the PDF merger and add your files by dropping them in or choosing them.
- Drag the files into the order you want them to appear.
- Start the merge. A progress indicator shows how far along it is.
- Download the combined PDF and scroll through it to confirm the order.
The merge runs on your device. Your files are not uploaded to any server.
What to do after merging
- Compress the result if it is too big to email
- Add page numbers so a long document is easy to reference
- Rearrange or delete pages if the order needs adjusting
- Extract specific pages if you only need to share part of it
Frequently asked questions
Is there a limit to how many PDFs I can merge?
In a browser the practical limit is your device's memory, not a fixed file count. Very large files or many files at once can be slower on older phones and laptops.
Will merging change the quality of my pages?
No. Merging copies the pages into a new document without re-compressing them, so the content stays as it was.
Can I merge PDFs and images together?
Yes. Convert the images to PDF first, then merge everything into one file.
