What you can do
Put files in any orderDrag them, use the arrow buttons, or sort by name or date. Numbers in names sort the way you expect.
Arrange single pagesType pages such as 1-3, 7 for each file, or open the Pages view to drag, turn, copy and remove single pages.
Locked files, damaged files and picturesEnter a locked file's password to merge it. Damaged files are repaired where possible, and pictures become pages.
Nothing lost on the wayLinks, bookmarks, notes, fillable fields and layers are carried into the merged file.
A little help along the way
Watch the tour, or follow the same steps below. Every option is explained underneath.
1 min 11 s, no sound. On-screen captions describe each step; the same steps are written out here.
1Add your PDFsDrop PDF files and pictures, choose them from your device or paste them. You can add more at any time, or try the samples.
2Put them in orderDrag a file, use its arrow buttons, or sort the list by name or date. Type the pages you want from a file, such as 1-3, 7.
3Arrange single pagesOpen the Pages view to select pages and drag, turn, copy or remove them. Every change can be undone.
4Organise the resultChoose how bookmarks are kept, add a contents page, set a password, or get the pages ready for printing.
5Merge and checkPress Merge PDF. Open the result in a new tab to look through it before you keep it.
6DownloadDownload the merged PDF under the name you choose. Nothing is uploaded: everything runs in your browser.
Every option explained
Pages
Write single pages and ranges separated by commas: 1-3, 7. An open range such as 10- runs to the last page, and -3 starts at the first. A backwards range such as 5-1 takes the pages in reverse. The words odd and even take every other page. A page may be listed more than once.
Sorting
Sort by name, by the date each file was last changed, or back to the order you added them. Numbers inside names sort by value, so chapter 2 comes before chapter 10. Moving a file by hand keeps your own order, and new files then go to the end.
Turning pages
The turn button rotates every page taken from that file a quarter turn clockwise each time you press it. Pages that were already turned inside the file keep that turn as well.
The same file twice
Add again puts a second copy of a file straight after the first, with its own pages field. Use it to place different parts of one file in different places.
Pages view
Shows every page of the result as a small picture. Click pages to select them, and Shift-click to select everything between two. Drag them to a new place, or use the toolbar to turn, copy, remove or move them, to reverse their order, or to add a blank page. Undo and redo cover every change. Look closely opens the reader at that page, with the pages in the order they will be merged.
The reader
Click a file's picture to read it in a large window: every page in one column, with zoom, fit to width, a strip of small pages, the file's bookmarks, and a field to jump to a page. Search finds words on every page and marks them. Text can be selected and copied, and links inside the file work. After merging, Read it here opens the merged file itself before you download it. Escape closes the reader.
Keyboard in the Pages view
Arrow keys move between pages, with Home and End for the first and last. Space selects, and Shift with an arrow selects on from there. Alt with the left or right arrow moves the selected pages, R turns them, and Delete removes them. Ctrl or Cmd with A selects all, with Z undoes and with Shift and Z does again. Escape lets go of the selection.
Your own page order
After the first change in the Pages view, the result follows your arrangement, not the file list. Files you add then join at the end, and removing a file takes its pages away. Start again from the files puts every file's pages back together and asks before it does.
Alternate pages
Takes the first page of each file, then the second of each, and so on. This joins a document that was scanned as two files, fronts and backs. Turn on the switch when the backs were scanned with the stack turned over, so that the last file is read from its end.
Pictures as pages
JPG, PNG, WebP, AVIF, HEIC, GIF, TIFF, BMP and JPEG XL pictures become pages. A picture takes the size of the page before it, or fits its own size, or goes on an A4 or Letter sheet, with a margin you choose. JPEG photographs go in as they are, without being compressed again, and are shown the right way up. See-through parts of other pictures become white. SVG is not accepted.
Locked files
A file that needs a password to open is merged once you enter it. The merged PDF has no password unless you set one under Password. A file whose author only restricted changes opens without a password; the page reminds you to make sure you may change it.
Damaged files
Files cut short by a failed download or with a broken index are repaired where possible, and the row says so. A file that cannot be read is left out, with the reason, and the rest are still merged.
What is kept
Pages are copied as they are, without re-compressing pictures. Links inside each file keep working, as do notes, fillable fields and layers. A link to a page you left out is removed. When two files have a field with the same name, the later one is renamed so both keep their own values.
Bookmarks
Under each file groups every file's bookmarks under an entry named after the file. Keep all lists them one after another. One per file makes a single bookmark for each file. None leaves them out. A bookmark for a page you left out is dropped.
Contents page
Adds a first page that lists every file and the page it starts on; each line is a link. List the files by name, or by the title each document carries inside. If the first file is a cover, the contents page comes after it and does not list it. Names in scripts the PDF's own font cannot write, such as Chinese or Arabic, are drawn as pictures.
Fillable fields
Keep leaves every field fillable and adds a number to a name another file already uses. Join same names turns fields with one name into one field, filled in once; the entry from the first file is kept. Flatten prints what is filled in onto the page and removes the fields. Remove takes out the fields and their entries.
Page numbers
This is the number a viewer shows beside each page, not anything printed on it. Count from 1 numbers the pages from first to last. Each file's own keeps the numbers the files gave their pages, such as Roman numerals for a preface.
Attachments
Files attached inside the PDFs are carried into the result unless you turn that off. When two share a name, the later one gets a number added.
Double-sided printing
Adds a blank page after every file that has an odd number of pages, so each file starts on a new sheet when the result is printed on both sides. An odd number of contents pages gets a blank page too. In your own page order, add blank pages yourself in the Pages view.
Page size
Fits every page onto one size: A4, Letter, the first page's size or the largest page's. Pages are scaled and centred, and a wide page gets the sheet on its side. Links, notes and fields move with the page. Turn off Enlarge smaller pages to keep small pages at their own size in the middle of the sheet.
Footer
Prints the file name, a page number, or both at the foot of every page: the number alone or as 3 of 12, at the left, centre or right, starting at the number you choose. The text is written over the bottom edge as it is, so check that nothing important sits there.
Other documents
Word, Excel, PowerPoint, EPUB and text files cannot be merged directly. Save or export them as PDF in the program that made them, then add the PDF.
Details
The title, author, subject and keywords that viewers and search tools show. Nothing is copied from your files unless you ask: Take them from the first file fills the fields, and you can change them.
Password
Locks the merged PDF with AES-256 encryption; the password is asked for whenever it is opened. You can also stop printing, copying or changes. Those limits rely on viewers respecting them, and a second password lifts them; left empty, a random one is used and thrown away. A lost password cannot be recovered.
Signatures and accessibility tags
A digital signature covers the exact file it was made for, so it cannot stay valid in a merged PDF. The signature's picture is kept and the row tells you. Accessibility tags are not carried over yet.
File size
Fonts and pictures that several files share are stored once, so the result is often smaller than the files together. Nothing is re-compressed, so quality does not change.
Limits and privacy
Up to 100 files and 5,000 pages in the result. On a computer, files can be 300 MB each and 500 MB together; on a phone, 100 MB each and 200 MB together, because phones close pages that use more memory. Everything runs in your browser: the files, their contents and any passwords stay on your device.
