What this tool does
Merge PDF joins two or more PDF documents into a single file. The pages appear in the order of the list: every page of the first file, then every page of the second, and so on. It's handy for putting a scanned ID next to an application form, combining monthly statements into one file, or sending a single attachment instead of five.
Features
- Any number of files. Add as many PDFs as you like, in one go or a few at a time.
- Easy ordering. Drag files into place, or use the arrow buttons (they work with the keyboard too).
- Original quality. Pages are copied without re-compressing, so text and images look exactly as before.
- No account, no watermark. Use it as often as you need. It's free.
Limits
- Files must be real PDFs. Word documents or images need converting first (see JPG to PDF).
- Encrypted PDFs must be unlocked before merging.
- Bookmarks, form fields and digital signatures from the original files are not kept in the merged file.
- Very large batches depend on your device's memory. If a merge fails, try fewer files at once.
Where your file is processed
This tool works in your browser: your PDFs are processed on your own device, so they aren't sent to our server for this tool. Some other tools on UtiloNest do use our server, and their pages say so.
Frequently asked questions
Where is my file processed?
In your browser. This tool works on your own device, so the file isn't sent to our server for it.
Is there a limit on the number of files or their size?
There is no daily limit, no file count limit and no watermark. The only limit is your device's memory. Most phones and computers merge dozens of ordinary PDFs easily; very large scanned files (hundreds of megabytes) may be slow on older phones.
Will merging change the quality of my PDFs?
No. Pages are copied as they are, so text stays selectable and images keep their original resolution. Links inside a page keep working, but bookmarks and form fields from the original files are not carried over.
Can I merge password-protected PDFs?
Not directly. If a PDF asks for a password when you open it, remove the password first with our Unlock PDF tool, then merge the unlocked copy.
Can I merge only some pages from each file?
Merge combines whole files. To pick certain pages, first use Split PDF to extract them, or Rotate & organize PDF to delete the pages you don't want, then merge the results.
