Need to combine several PDF files into one? Whether you're submitting a job application, sending invoices, or collating a report, merging PDFs is one of the most common tasks people need to do with documents. The good news: you don't need expensive software or a subscription. Here are three proven methods — all free.
🧩 Merge PDFs instantly — free
No sign-up. No file size fuss. Works in your browser.Method 1: Merge PDFs Online (Fastest, No Software)
The quickest way to combine PDFs is to use a browser-based tool. No download, no account, no cost. Here's exactly how to do it using EasyPDF Studio's free Merge PDF tool:
Visit easypdfstudio.co.uk/merge-pdf. No account needed.
Click "Select Files" or drag and drop your PDFs into the upload area. You can add multiple files at once.
Drag files into the order you want them to appear in the final merged document.
Hit the merge button and download your combined PDF instantly. The file is ready in seconds.
Method 2: Merge PDFs on Windows (Using Microsoft Edge)
If you prefer to work without any internet tool, Windows users can use Microsoft Edge's built-in print-to-PDF feature — though this works best for small numbers of files.
- Open the first PDF in Microsoft Edge.
- Press Ctrl + P to open the print dialog.
- Set the printer to Microsoft Print to PDF.
- Repeat for each document and combine pages manually.
Limitation: This method is fiddly for more than 2 files and doesn't preserve interactive elements. For anything beyond a quick combine, the online method above is faster and more reliable.
Method 3: Merge PDFs on Mac (Using Preview)
Mac users have a built-in option via the Preview app:
- Open the first PDF in Preview.
- Go to View → Thumbnails to show the sidebar.
- Drag and drop additional PDF files from Finder into the sidebar at the position you want.
- Go to File → Export as PDF to save the merged file.
This is a solid method for Mac users who work offline, but it requires a bit more manual steps than the browser-based approach.

Tips for Better Results When Merging PDFs
- Check page order before merging. Once merged, reordering pages requires splitting and re-merging.
- Compress large files first. If your PDFs are big, compress them before merging to keep the final file size manageable.
- Remove passwords first. Password-protected PDFs can't be merged until unlocked. Use the Unlock PDF tool first.
- Convert other formats first. Need to include a Word document? Convert it to PDF first, then merge.
Common Questions
Can I merge PDF files for free?
Yes. EasyPDF Studio's Merge PDF tool is 100% free with no sign-up required. It runs directly in your browser so nothing is installed on your device.
Is it safe to merge PDFs online?
EasyPDF Studio processes files locally in your browser where possible. Your files are not stored on any server after your session ends. For sensitive documents, always check the privacy policy of any tool you use.
How many PDFs can I merge at once?
You can merge multiple PDFs in one session using the EasyPDF Studio tool. There are no strict limits on the number of files, though very large batches may take slightly longer to process.
Will merging reduce the quality of my PDFs?
No. Merging PDFs simply combines the files — it does not re-compress or alter the quality of images or text within the documents.
