Combine multiple PDF files into one document instantly.
Click the Add PDF files button and choose the PDF files you want to merge from your device.
Drag and drop the files or use the controls to set the order in which the pages should appear in the final merged PDF.
Optionally adjust settings like file limits or page ranges if the tool provides them.
Click the Merge PDFs button and wait for the processing to finish, then download your merged PDF file.
Is this PDF merger free and secure?
Yes. Nextooly is completely free and 100% secure. Unlike other sites, we do not upload your files to a server. All processing happens locally in your browser.
Does this tool work on Mac and Windows?
Yes, it works on any device (Mac, Windows, Linux, Android, iOS) with a modern web browser like Chrome, Edge, or Safari.
Why were some of my PDFs skipped?
The tool automatically skips password-protected (encrypted) or corrupted files. Please remove the password using your PDF viewer before merging.
Can I reorder the PDFs before merging?
Yes. Simply drag and drop the files in the list to rearrange them, or use the 'Sort by file name' button.
Is there a file size limit?
We recommend a total size of under 60 MB for the best performance, as the merging happens entirely within your browser's memory.
Why can't I merge password-protected PDFs?
For security reasons, our browser-based tool cannot decrypt locked files. You must unlock them on your computer first.
How do I save the combined file?
After clicking 'Merge', the file is generated instantly. You can enter a custom name or leave it blank to save it as 'merged.pdf'.
Why does merging take time for large files?
Since the processing happens on your device (not a supercomputer server), the speed depends on your computer's CPU and the complexity of the PDF pages.
