Merge PDF files in your browser
Use this PDF merger when you need one document from several source PDFs, such as combining scanned pages, joining signed forms, or packaging reports for sharing. Add two or more files, review their page counts, then arrange the queue before creating the final PDF.
How the merge order works
Pages are added in file order: all pages from the first PDF, then all pages from the next. Use the arrow controls or drag rows on desktop to reorder files. You can also remove files and preview each PDF before merging.
Privacy and file handling
All parsing and merging runs locally in your browser with pdf-lib and a background worker. Your files are not uploaded to a server, and the generated download link is available only in the current browser session.
Limitations
Encrypted or damaged PDFs cannot be merged reliably. If a file is protected by an owner password, remove that restriction first and add the unlocked PDF again. Very large files may take longer because the browser has to copy every page into a new document.
