How to use the Merge PDF tool
Three steps, nothing to install, no account needed.
- STEP 01
Add your files
Drop in two or more PDFs: up to 3 at a time without an account, or 10 with a free one.
- STEP 02
Set the sequence
Drag the rows until the order is right, or let the tool sort them by filename.
- STEP 03
Download
One merged PDF, ready to send or print. It usually takes 2 to 5 seconds.
What the Merge PDF tool does
Drag to reorder
Set the exact page sequence before merging. What you see is what you download.
Nothing re-encoded
Pages are copied as they are, so scans stay sharp and text stays selectable.
Bookmarks kept
Each file's bookmarks come across and point at their new pages, so a long document stays easy to navigate.
Links keep working
Jumps to another page follow it to its new page number. Links to websites stay exactly as they were.
Smart filename sort
Sort by filename and numbered scans land in order, scan-2 before scan-10, with no renaming.
Done in seconds
Most merges finish in 2 to 5 seconds, because nothing has to be redrawn.
Merge PDF: a complete guide
Merging is not converting
This is worth knowing, because it explains why combining PDFs is quick and why you can merge PDF files without losing quality.
Pages are copied from each source file into one new document, end to end, which is all that concatenating PDFs means. A scanned page stays a scan. A vector diagram stays vector. Embedded fonts come across untouched.
So the answer to "will merging make my PDFs blurry" is no. Nothing in the merge itself changes how a page looks.
How to combine PDF files into one
- Add all your PDF files in one go. Drag them in or select them from your device.
- Set the page order how you want by dragging, or set File order to Filename A–Z or Upload order.
- Merge, and the combined PDF downloads as a single file.
Sorting by filename is typically the easiest way to arrange numbered files in the right order before you join them, and it also respects numbers, so scan-2 will come before scan-10. There's no need to rename them with leading zeros, like scan-02, first.
What happens to bookmarks and links
Internal links that point to another location within the same file are moved to their new page number, so they still work. Links to websites are untouched.
Bookmarks from each file are retained and point to the same place in the merged PDF. On a long report, this means being able to jump to a specific page from the side panel.
Merging PDFs on iPhone, Android, Mac or Windows
This PDF merger runs in the browser, so combining PDFs works the same way on all devices, with no installation required.
On an iPhone or Android phone, you'll tap to select files from Files, Google Drive or your downloads. On a Mac or Windows PC, you drag files from wherever you've saved them.
The merged PDF then downloads like any other file.
Password protected PDFs
A PDF that needs a password to open can't be merged as it is. Remove the password first with Unlock PDF, then add the unlocked copy here.
Common uses
- Putting together a job application, with your CV, cover letter and any required certificates in one file.
- Combining monthly statements or invoices for your accountant.
- Joining scanned pages that your scanner has saved as individual files.
- Building one report from chapters contributed by different people.
- Turning a stack of receipts into a single expense claim.
Is the Merge PDF tool free?
Yes. You get 20 credits a day with no account and no email address.
This tool costs 1 credit per file, so a three file merge costs 3 credits. There is no watermark on the result. A free account raises that to 50 credits a day, 100 MB per file and 10 files at a time.
- 20 credits a day, refreshed daily
- 1 credit per file
- Up to 3 files at a time, 25 MB each
- No account, no email, no card
- No watermarks on the merged PDF
Free merges run in the normal queue. Paid plans take more files at once, and from Standard upwards move you to the priority queue, which helps on very large jobs.
Is it safe to upload my documents?
Yes. Your files are deleted from our servers one hour after processing, automatically.
Nothing is stored past that hour. Nothing is read by a person. Nothing is used to train anything. Every upload and download runs over HTTPS, so your file is encrypted both ways.
This one matters. People merge bank statements, contracts and medical letters. The deletion runs on a timer, so you do not have to remember to clear anything, and there is no button to hunt for.
Common problems and fixes
Most of these come down to the order, the file size or a password. Here is what to change.
| Problem | Why it happens | Fix |
|---|---|---|
| Pages are in the wrong order | Files went in the order you picked them | Drag the rows, or set File order to Filename A–Z |
| The merged file is very large | The source PDFs are full of large scans | Run the result through Compress PDF |
| A file will not merge | It is locked with a password | Remove the password with Unlock PDF, then add the unlocked file |
| A file will not upload | It is larger than 25 MB | Sign in for files up to 100 MB, or shrink it first with Compress PDF |
| Only some of your files were added | More than 3 files at once without an account | Merge them in groups of 3 and then merge the results, sign up free for 10 at a time, or use a paid plan, which takes 20 or more at once |
| Some pages are sideways | They were rotated in the source file | Fix them with Rotate PDF after merging |
| You want to join images, not PDFs | Wrong tool | Use JPG to PDF instead |
| You merged too much and need part of it | Wrong tool for that step | Use Split PDF to pull pages back out |

Merge PDF — frequently asked questions
Short, straight answers to what people ask most.
How do I merge PDF files into one?
Add your PDFs, put them in the order you want, and hit merge. The combined PDF downloads as a single file, usually within 2 to 5 seconds.
Does merging reduce the quality of my PDFs?
No. The pages are copied across exactly as they are, so nothing gets re-encoded or blurred. A scan stays a scan and text you could select before is still selectable after.
How many PDFs can I merge at once?
Without an account it's 3 files at a time, each up to 25 MB, and every file uses 1 credit out of your 20 free credits a day. A free account takes 10 at a time. For a bigger stack, merge in groups and then merge the results. Paid plans take 20 or more files at once.
Can I change the order of the files?
Yes. Drag the rows into the order you want before merging. You can also set File order to Filename A–Z, which handles numbered scans properly, or keep the order you uploaded them in.
Is there a watermark on the merged PDF?
No, on any plan. The file you get for free is the same file a paying customer gets. We don't add a mark and then sell its removal.
Can I join password protected PDFs?
Not straight away. A PDF that needs a password to open has to be unlocked first. Run it through our Unlock PDF tool with its password, then merge the unlocked copy here.
Do bookmarks survive the merge?
Yes. Each file's bookmarks come across, and they point at the same pages as before, at their new position in the merged document.
Will links inside the PDF still work?
Yes. A link that jumps to another page of the same document is moved to that page's new number. Links to websites are left exactly as they were.
Can I combine PDFs on my phone?
Yes. It runs in your phone browser on Android and iPhone, with nothing to install. Tap to choose files from Files, Google Drive or your downloads, then merge and download.
How do I reduce the size of a merged PDF?
Merging doesn't shrink anything, because the pages are copied as they are. If the result is too big to send, run it through our Compress PDF tool afterwards.
Can I merge images and PDFs together?
Turn the images into a PDF first with our JPG to PDF tool, then merge that file with your other PDFs here.
