Merge PDF Files Free, With No Limit
Combine multiple PDF files into a single document, in the order you choose. None of your files are ever uploaded to a server: the merge happens directly in your browser.
Open the tool — it's freeNo sign-up. Your file never leaves your device.
How it works
Add your PDF files
Drag at least two PDF files into the drop zone, in the order you want them merged.
Check the list
Remove a file if needed by clicking the small button next to its name.
Merge and download
Click "Merge and download": the combined document is generated instantly.
Why it's private
Your file is read by your browser, in memory, and the conversion runs directly on your computer. It's never uploaded to a server — not ours, not anyone else's. Close the tab and it's all gone. See how to verify this yourself →
Frequently asked questions
How many PDF files can I merge at once?
There's no limit set by the tool. The only constraint is the memory available on your device for very large files.
Is the order of the files preserved in the final document?
Yes, the pages are assembled in the order you added the files.
Can password-protected PDFs be merged?
PDFs with strong encryption may fail to merge. Remove the password protection before adding them if possible.
Do I need to create an account to use FiloConvert?
No. There's no account, no sign-up, and no email required. Open the page, convert, download.
Is there a file size limit?
There's no server-imposed limit, since there's no server involved: the conversion happens on your device. The only limit is the memory available on your computer or phone.
