Welcome to Randomly.online's Merge PDF tool, a robust and secure solution designed to combine multiple PDF documents into a single, organized file directly in your web browser. Unlike traditional server-side tools where your sensitive documents are uploaded to a remote server, our tool processes everything locally on your device. This ensures that your private contracts, reports, and personal data never leave your computer. You can also convert multiple images to a single PDF if your inputs aren't already documents.
Whether you are a student compiling assignments, a professional organizing reports, or simply someone trying to declutter their digital workspace, this tool provides a streamlined workflow. You can easily drag and drop files, visualize the first page of every document, and rearrange the order. If you need to fix file properties before merging, you might want to rotate PDF pages that are upside down.
Begin by clicking the "Upload PDFs" button or dragging your PDF files directly into the dashed drop zone. As soon as you add them, the tool will analyze the documents and generate a thumbnail preview. If your files are too heavy, consider using our compress PDF tool beforehand.
Once your files appear as cards in the list, you can arrange them in the order you want them to appear in the final document. Use the "Move Up" (<) or "Move Down" (>) arrows on each card to shift their position. If you have specific content you need to pull out, you can extract text from PDF separately.
Check the toolbar for options like "Standardize Size," which attempts to scale all pages to a standard A4 format. When satisfied, click the large "Merge PDFs" button. A progress bar will indicate the processing status.
Once processing is complete, a "Download Merged PDF" button will appear. Click it to save your new file instantly. You can even convert text files to PDF and merge them into your main document workflow easily.
Absolutely. This is a client-side tool, meaning the actual merging process happens within your browser's memory. Your files are not uploaded to our servers, stored, or viewed by us. Once you close the tab, all data regarding the session is cleared from your browser's memory.
There is no hardcoded limit on the number of files you can merge. However, since the processing happens on your device, performance depends on your computer or phone's RAM. Merging hundreds of large files simultaneously might slow down older devices, but typical usage (10-50 files) works seamlessly. If you need images out of these files later, check our extract images from PDF tool.
Currently, the tool requires PDF files to be unlocked before merging. If you try to upload a password-protected PDF, the tool may fail to generate a thumbnail or merge the specific file. We recommend using our PDF unlocker tool before attempting to combine them here.
