Free Online Merge PDF Tool – Combine Multiple PDFs into One
The Merge PDF tool from ConvertFree.net lets you combine several PDF files into a single, tidy document in just a few clicks. Instead of emailing a messy collection of attachments, you can upload your files once and download one clean PDF that keeps everything together. It’s ideal for combining reports, slide decks, scanned pages, contracts, invoices and more into one organized package.
All merging is processed directly on our servers using the Imagick engine, without sending your documents to any external conversion APIs or third-party platforms. You simply drag and drop your PDFs into the upload area, wait a few seconds and then download the final merged file. The pages are added in the order that the files are processed, so you can control the flow of your final document by selecting your PDFs in the desired sequence.
Use this Merge PDF tool together with other ConvertFree.net utilities for a full workflow. You can split PDF files first to extract just the sections you need, then merge those pieces into a new document. After merging, you can run the final file through our Compress PDF tool to reduce file size for email and uploads. If you need to convert pages to images before or after merging, our PDF to JPG and PDF to PNG converters are ready, along with JPG to PDF and PNG to PDF to go in the opposite direction.
For most documents, the merge process keeps the page content visually consistent. In order to run reliably on shared hosting, the tool renders pages as images under the hood, which means bookmarks and interactive form fields may not be preserved as live elements. However, the visual layout, text and graphics remain intact, giving you a final merged document that is easy to read, print and share.
ConvertFree.net is designed with a clean interface and an ad-friendly layout that works well with Google AdSense policies. There are no watermarks, no forced signups and no confusing menus – just a straightforward Merge PDF tool that you can bookmark and reuse whenever you need to combine multiple PDF files into a single, professional document.
Merge PDF – Frequently Asked Questions
How do I merge multiple PDF files into one on ConvertFree.net?
Click inside the upload area or drag and drop your PDF files, then press “Merge PDF files”. ConvertFree.net processes your uploads on its own servers and generates a single merged PDF that you can download with one click.
Can I control the order of pages when merging PDFs?
Yes. The pages are merged in the order that your files are processed, which is based on the sequence you select them in the upload dialog or drag-and-drop. To control order, simply choose or drop your PDFs in the same sequence you want them to appear in the final document.
What is the maximum size or number of PDFs I can merge?
The current limit is a total of 80 MB for all uploaded PDFs combined. This helps keep the merge process fast and stable on shared hosting while still covering most real-world cases such as combining several reports or slide decks. If your PDFs are very large, consider compressing or splitting them first using Compress PDF or Split PDF.
Will bookmarks, links and form fields be preserved?
To run reliably in all environments, this tool uses an image-based rendering approach through Imagick. That means visual content – text and graphics – is preserved, but interactive elements like bookmarks, internal links and live form fields may be flattened and no longer editable. For sharing and printing, the merged result will still look like your original documents.
Are my PDF files safe and deleted automatically?
Yes. Your PDFs are processed only on ConvertFree.net servers and are never sent to external APIs. We also run an automated cleanup routine that regularly removes old files from our storage folders, so your documents are not kept longer than necessary.
