Merging multiple PDFs into a single file is one of the most common document management tasks: contracts with attachments, multi-section reports, presentations made up of separate files. With OnlinePdfEditor you can do it directly in the browser, with no software to install and no account to create.
The process is straightforward: upload the files in the order you want, rearrange pages with drag & drop if needed, and download the final document. Everything happens locally on your device via WebAssembly — no files are uploaded to any server.
Metadata, internal links and bookmarks from the original documents are preserved to the extent that the pdf-lib library can copy them. External URL links are always kept.
You can merge as many files as you like. There is no hard limit on the number of documents, but speed depends on the total file size and your device's performance.
