Merge PDFs

Combine two or more PDF files in the order you choose, without uploading them.

Add PDF files

Choose files to begin.
Review edited PDFs before relying on them. Creating a new PDF can change or omit advanced features such as forms, annotations, bookmarks, links, metadata, embedded files, accessibility tags, encryption, and digital signatures. Existing signatures will no longer be valid after modification.

How to combine PDF files

Add at least two PDFs, arrange the documents with drag-and-drop or the move buttons, choose Merge PDFs, then explicitly download the finished file. Pages from each document stay together and retain their original dimensions.

Private PDF merging

Unlike server-based workflows, this tool processes each document locally in your browser. Document contents, filenames, and output are never sent to One Job Tools.

Frequently Asked Questions

Add two or more PDFs, arrange them in the order you want, select Merge PDFs , and download the combined document.

No. Your input files and merged PDF are processed locally in your browser and are never uploaded to One Job Tools.

Yes. Letter, A4, landscape, portrait, and other page dimensions can be combined. Each page keeps its original size and orientation.

The tool copies pages into a new PDF instead of converting them to screenshots, so it does not intentionally recompress page images or reduce their resolution.
