Merge PDF
Combine several PDFs into one document. Drag pages into the order you want, rotate or remove any page, add page numbers and check the finished PDF before you download. Your files stay on your device.

Every page, in order
All the pages of all your files appear in one grid. Drag any page to move it, even between files, and remove the ones you do not need.
Fix pages as you go
Turn a sideways scan upright with the rotate buttons, or delete a blank page, without a separate tool.
Number the whole set
Add page numbers across the merged file: choose the corner, the style, the first number and whether page 1 is numbered.

The live preview is the finished PDF. Open Preview final PDF to scroll every page at full size before you download.

About Merge PDF
PDFEditKaro's Merge PDF tool joins two or more PDF files into one. Every page of every file appears in a single grid, so you can drag a page to a new position (even between files), rotate a sideways scan, remove a blank or unwanted page, and see exactly what the merged file will look like. There is no limit on the number of files, no watermark, and nothing is uploaded: the merge runs entirely on your device.
The live preview shows the finished PDF page by page, with page numbers if you add them, and Preview final PDF opens every page at full size. Page numbers run across the whole merged file: choose the corner, the style such as Page 1 of 10, the first number, the size and the colour, and leave page 1 unnumbered if it is a cover. Typical uses include combining scanned pages, assembling an application with its supporting documents, joining chapters of a report, or putting several invoices into one file for your accountant.

Frequently asked questions
How many PDF files can I merge?
There is no fixed limit. The practical limit is your device's memory, so very large files (hundreds of megabytes in total) may be slow on older phones. A laptop or desktop handles them best.
Can I rotate or remove pages while merging?
Yes. Each page in the grid has buttons to rotate it left or right and to remove it. Pressing Undo remove brings back the last page you removed.
Can I put pages from different files in a new order?
Yes. Drag a page anywhere in the grid, even between pages of another file. The move-file arrows regroup the pages of a file together.
Can I add page numbers to the merged PDF?
Yes. Tick Number the merged pages, then choose the position, format, size, colour and first number. The numbers continue across all the files and also appear correctly on rotated pages.
Will merging reduce the quality?
No. Pages are copied as they are, so text, images and page sizes stay the same. Nothing is re-compressed.
Can I merge password-protected PDFs?
Not directly. Remove the password in the program that created the file, then add it here. We tell you which file is protected.
Are my files uploaded anywhere?
No. The files are read and combined by your browser. Closing the tab clears them.
