PDF Merger — Merge PDFs Offline

Combine multiple PDF files into one clean document without sending them to a website. PDF Merger is a focused Chrome extension for joining PDFs locally in your browser. Select the files, arrange them in the right order, and create one downloadable PDF in a few steps. PDF Merger keeps merge as its primary workflow, while also including related tools for broader PDF work. You can split or extract pages, compress and rotate files, protect PDFs, add watermarks, convert PDF pages to images, and turn images into PDFs. You can also unlock authorized files, repair documents, manage metadata, delete or reorder pages, and crop page areas. These options support the main workflow; merging remains the central purpose of the extension. Choose files, check the order, merge, review the result, and download it. No upload, account, or separate web service is needed. Your PDF data is processed in-browser and stays on your device. Why use a local PDF merger? Combining contracts, invoices, applications, research papers, receipts, or scanned documents through an online tool can add unnecessary steps. A browser-based PDF merger prepares the final document on your computer. PDF Merger brings several PDF files together in a predictable order. What you can do 1. Add multiple PDF files Select PDF documents from your computer or drag them into the upload area. Add or remove files from the list as needed. 2. Set the document order Arrange the files with drag and drop. The file list order becomes the page order in the merged PDF. 3. Check your selection Review file names, page counts, sizes, and thumbnails before you start. Clear the selection when needed. 4. Merge PDF files offline Start the merge when the files are ready. The extension combines the documents in your browser without uploading the source files. 5. Preview and download Review the generated document in the built-in preview, then download the merged PDF. Useful for everyday document work • Combine a signed cover letter with supporting pages. • Join invoices, receipts, or order documents into one record. • Put a report and its appendices into one PDF. • Assemble application materials in the order requested. • Keep a scanned document set together for local storage or sharing. • Prepare a single document for your normal workflow. The interface is direct. No project, complex setup, or new document format is required. PDF Merger keeps the primary workflow visible: select files, arrange them, and merge. 🔒 Local processing and privacy PDF Merger is built around local, in-browser processing for the merge workflow. • Source PDFs are selected from your device. • Documents are processed in browser memory. • No source PDF upload is required. • Chrome downloads the merged result to your computer. • You can review the output before downloading it. Keep sensitive documents on your device without an upload or online account. Important compatibility note The merge workflow accepts PDF files. Password-protected or encrypted PDFs may need to be unlocked with the correct password before merging. If a document cannot be read locally, the extension reports the problem instead of producing an incomplete file. Confirm that you have permission to combine the selected documents. Built around the primary merge workflow PDF Merger works locally without a website tab, file transfer, or complicated setup. Choose files, arrange them, select Merge PDFs, review the result, and download it. Original files stay on your device while the result is created separately. Supporting tools extend the same local document workflow without taking focus away from merging. FAQ What is PDF Merger?
