Merge PDF online, free
Put several PDFs together into one file. Drag them into the order you want.
How to use Merge PDF
- Choose two or more PDFs at once, or add them one at a time.
- Drag the files into the order you want them in the final document.
- Press Merge PDFs. Batches over 50 MB are joined on your device instead of the server, so no file is dropped.
- Download one PDF with every page, in the order you set.
Merge PDF: common questions
Can I change the order?
Yes. Drag the files, or use the arrows next to each one, before you merge.
Is there a limit on how many PDFs I can merge?
No. There is no daily or monthly limit and no account, and it stays free for life: use it as often as you like. Add as many files as you like. Files up to 50 MB in all are processed on ScalePDF’s server; bigger ones are processed right on your device, which can take a little longer.
Is my file uploaded?
Only while it is being processed. Your file goes to ScalePDF’s server over an encrypted connection, is worked on in memory, and is deleted the moment the result comes back. Nothing is stored, logged or shared.
