Quickly join PDF files

What about non-PDF files?

 

To merge PDF files with other formats, do check out our other online tool to convert different file formats into PDF format. Afterward, you can access the PDF joiner to combine them all into one single document. As with the PDF merger, all of our other tools are also free to use.

Other than converting, Smallpdf can also split, rotate and annotate your PDF files. A list of all available tools is listed via our homepage for you to check out.

I am experiencing slow download speed

 

Although the maximum file size limit is 5GB per file, it might still take quite some time to upload and merge multiple PDF files. In this case, you can try to compress your files before the merging, which should cut down the time spent on upload significantly.

To further speed up this process, you can sign up for a Pro account, which enables batch compression. Furthermore, Pro users also have access to 40% faster upload speed on our online platform!

Is your service safe to use?

 

Security is our primary concern; both our website and all file transfers are encrypted, and all files are always deleted from our servers after one hour from our protected environment. For extra security, you can always opt to encrypt your PDF further with a password.

Offline PDF joiner

 

If you are not a fan of uploading your PDF documents online, there is also the option to go for the offline PDF joiner app, which allows you to carry out the same function, without the need to upload any documents — same handy tool, same output quality - just slightly less tedious.

On top of that, it comes with a handy PDF reader, so you can check the resulting document right after joining them.

And that’s all there is when it comes to PDF joining. Remember to bookmark us for whenever you need help with your PDF documents, and spread the word about our service with your friends and family!
