Merge and Reorder PDF Online in Seconds
Combine PDFs and rearrange pages visually for a clean, shareable file.
Why merge and reorder together
Merging PDFs is the fastest way to collect documents into one file, but page order matters. A visual reorder step saves time and prevents mistakes before sharing.
OpenPDF keeps everything in your browser, so you can merge files and drag pages into the right order without uploading to a server.
Quick workflow
1) Merge PDFs in the order you want. 2) Open the editor and drag pages to finalize the sequence. 3) Download the reordered PDF.
If you download multiple times, OpenPDF auto-adds a sequence number to keep each export unique.
Best practices
Use clear file names, remove blank pages, and preview page thumbnails before download.
For large files, reorder first, then remove pages to keep the final PDF compact.
