Merge PDF files
Join contracts, scans and reports into a single PDF. Drag the files into order, sort them by name if that helps, and merge. The work happens in your browser, so private documents never reach a server and there is no limit on pages or files.
Tooloat runs in your browser and needs JavaScript. It opens in a moment, and your files are processed on your device.

Questions and answers
Is there a limit on file size or pages?
No fixed limit. Very large files depend on the memory of your device.
Will links and bookmarks survive?
Pages, sizes and rotation are kept. Bookmarks and form fields are not carried over into the merged file.
Are my PDFs uploaded?
No. Merging uses pdf-lib inside your browser tab.
