Merging PDFs with Rai Paruhang takes under a minute — no account, no upload, and nothing installed. Here is everything you need to know, including tips for specific devices and advanced options.
Upload your PDF files
Drag and drop multiple PDFs into the upload area, or click Choose PDFs to pick files from your device. You can add as many files as you need — there is no limit.
Reorder and set page ranges (optional)
Drag the file cards to set the order you want in the final PDF. For each file you can also enter a page range — for example 1-3, 5 — to include only specific pages instead of the whole document.
Merge and download
Click Merge PDFs and your combined file is ready in seconds. Click Download PDF to save it. The file is created entirely inside your browser — nothing is sent to any server.
Open this page in Safari, Chrome, or Firefox on your Mac — no software installation needed. Drag your PDF files from Finder directly into the upload area, arrange them as needed, then click Merge. The downloaded file lands in your Downloads folder just like any other file. This works on every version of macOS that supports a modern browser, including macOS Ventura, Sonoma, and Sequoia.
Open this page in Chrome, Edge, or Firefox on your Windows PC. Click Choose PDFs to browse your files, or drag them in from File Explorer. There is no need to install Adobe Acrobat or any other program. The merge happens locally in your browser, so it works even on work computers where you cannot install software.
The tool works on mobile browsers too. On iPhone, open the page in Safari and tap Choose PDFs — you can select files from the Files app, iCloud Drive, or your photo library. On Android, use Chrome and pick files from Google Drive or your local storage. After merging, tap the download button and the combined PDF saves to your device. No app download required.
You do not have to include every page from each file. After uploading, each file card shows a page range input. Type a range like 1-3 to include only the first three pages, or 2, 4, 6 to pick individual pages. This is useful when you want to extract and combine specific chapters or sections from several documents without editing each file separately.
After uploading your files, drag and drop the file cards to set the page order in the final document. The card you place first becomes the first section of the merged PDF. You can also click Sort A–Z to sort files alphabetically by filename, which is handy when working with numbered documents like chapter-1.pdf, chapter-2.pdf, and so on.
Unlike iLovePDF, SmallPDF, or Adobe online tools, this merger does not upload your files to any server. All processing happens directly in your browser using JavaScript. Your documents never leave your device, which makes it safe for confidential files like contracts, medical records, or financial statements. You can even use it offline once the page has loaded.
Merge fails when one of the PDFs is password protected.
