Merge PDF
Choose your files, set the order with the arrows and press Merge.
How to use
Pick two or more PDFs. Pages in the finished document follow the list exactly, so reorder the files with the arrows if you need to. The cross removes a file you added by mistake.
The difference from the big services that fill the first page of search results: your file never leaves the browser. For a contract, a passport scan or a medical record that is decisive — the document physically cannot end up on someone else's server, because it is never sent anywhere.
FAQ
Are the files really not uploaded?
Really. Merging is done by a library that runs inside the browser. You can prove it: disconnect from the internet after the page has loaded and the tool keeps working.
Is there a limit on file size or count?
There is no fixed limit; your device's memory is the boundary. A dozen ordinary documents merge instantly, while a hundred heavy scans on an older phone will take a while.
What about password-protected PDFs?
An encrypted file cannot be read, and the tool will say so. Remove the password in whatever program applied it and try again.
Are bookmarks and links preserved?
Pages carry over with their content and layout, but the table of contents and internal links from the source files are not preserved when merging. That is a limitation of the method rather than a setting.
