SubMac / Free tools / Merge PDF
Merge PDFs into one, right on your device.
Drop your PDFs, put them in order and download one tidy file. Free, no watermark, nothing uploaded.
Files never leave your device. Everything happens in your browser.
How it works
Three steps. That’s it.
- 01
Add your PDFs
Drop them in or choose them from your device.
- 02
Put them in order
Drag the files, or use the arrows, so they read top to bottom.
- 03
Merge and download
One click joins them into a single PDF.
Questions
Good to know.
Are my files uploaded?
No. The PDFs are joined by your browser on your own device. Nothing is sent to our server, so it works for private documents too.
Is there a limit on files or size?
There’s no fixed limit. Very large files (hundreds of MB) depend on your device’s memory; on a phone, keep the total under about 200 MB.
Will links and text stay selectable?
Yes. Pages are copied as they are, so text stays sharp and selectable. Fillable form fields may be flattened or lost in some files.
Can I merge password-protected PDFs?
Not yet. Remove the password first (open it and save or print it to PDF), then merge.
Is it really free?
Yes. No sign-up, no watermark and no daily limit.
