PDF Merge

PDF Merge

PDF Merge combines two or more PDF documents into a single file directly in your browser. Upload your files by clicking the upload button or dragging them into the drop zone, arrange the order with drag-and-drop or arrow controls, and download one unified document in seconds. Beyond merging, five built-in sub-tools handle splitting, rotating, extracting, and removing pages from any PDF. Every operation runs client-side using JavaScript, so your documents never leave your computer or travel across the internet.

Online PDF Merge with Drag-and-Drop Reordering

Arranging your files in the correct sequence is just as vital as the merge itself. Once you upload your documents, they appear as cards showing the filename and page count. You can easily drag these cards to reorder them or use the arrow buttons for more precise control. Your list updates instantly, allowing you to double-check the order before you download the final result.

Upload Multiple Files at Once

To get started, select several PDFs from your file browser or drag a batch of files directly into the workspace. The tool validates each file immediately and displays the page count right next to the name. If a file is incompatible or corrupted, you will see a clear error message while the rest of your documents continue to load normally.

Split, Rotate, and Extract in One Workspace

You can switch between different tools with just a single click. Whether you need to split a PDF into individual pages, rotate a scanned document, or remove unnecessary pages, the interface makes it simple. Each new task starts with a clean workspace to help you stay organized while you work.

How to Use PDF Merge Step by Step

Begin by selecting the Merge PDF tab from the toolbar, then upload or drag your files into the workspace. You can rearrange your documents until they are in the perfect order for your final file. Once you are ready, click the Merge and Download button to combine everything. Your new PDF will download automatically, so it's ready to share or archive immediately.

Page Range Syntax for Split, Extract, and Remove

The split, extract, and remove tools all support flexible page ranges to give you total control. You can enter individual page numbers separated by commas, use hyphens for ranges, or mix both styles. If you leave the range field empty in split mode, the tool will create a separate file for every single page. Any invalid or out-of-range numbers you enter are simply ignored.

Rotate Scanned Documents to the Correct Orientation

It is common for scanned PDFs to appear sideways or upside down, but you can fix this in one simple step. Just choose your rotation angle, apply it to specific pages if needed, and download the corrected document. Your original content remains pixel-perfect because the tool only adjusts the orientation of the pages.

Free PDF Merge for Students, Professionals, and Teams

Merging PDFs is a frequent necessity, whether you are a student combining research papers or a professional assembling reports and contracts. This tool handles these tasks easily without requiring any registration, software downloads, or payments. Since all the processing happens right in your browser, you don't have to deal with server-side file limits or long upload queues, ensuring your data remains private.

No Signup, No Watermark, No File Limits

You can access every feature the moment you open this page, with no account walls, premium tiers, or watermarks on your finished files. Feel free to merge, split, rotate, or extract pages as many times as you need. To protect your privacy, all session data is permanently cleared from memory as soon as you close the browser tab.

Client-Side Processing for Complete Privacy

Your PDF files remain on your computer throughout the entire process, ensuring complete privacy. This tool utilizes the pdf-lib library to handle all document manipulations locally without any server communication. This means your confidential contracts, financial statements, and personal records never leave your device. Nothing is ever uploaded, stored, or logged.
