How to use Merge PDF
Select two or more PDFs in the order they should appear. The tool copies every page into a new file, which you can download straight away.
Good to know before you merge
Files are joined in the order you select them, so pick the cover page or first chapter first. You can merge up to 50 MB of files with up to 200 pages in total. Password protected PDFs need to be unlocked first, because the tool cannot read encrypted pages.
Why merge in the browser
Contracts, bank statements and medical letters are not things you want sitting on a stranger’s server. Here the work happens on your own device, the same way it would in desktop software, so the files never leave it. It is also quick, because there is nothing to upload or wait for.
Getting the best merged file
Rename your files with numbers first, such as 01 cover, 02 report and 03 appendix, so they are easy to pick in the right order. The merged file keeps every page exactly as it was, so text stays selectable and scans keep their resolution. If one of the files is very large, its pages make the merged PDF large too; compress that file first. Files saved in Google Drive or email need to be downloaded to your device before you can combine PDFs here.
Nothing to delete afterwards
Many online PDF merger sites upload your documents and promise to delete them from their servers after an hour. Here there is no upload at all, so there is nothing to delete. The pages are copied inside your browser tab, and closing the tab clears them.
