Need to merge multiple PDF files into one, or split a large PDF into separate files? Our free PDF merger and splitter tool makes it easy to combine or separate PDF documents. Whether you're organizing documents, creating reports, or managing large files, merging and splitting PDFs helps you work more efficiently.
Our PDF tool supports both merging multiple PDFs into a single document and splitting a PDF into individual page files. The tool works entirely in your browser, ensuring your documents stay private and secure. No signup required, completely free, and ready to use instantly.
In this guide, you'll learn how to merge PDFs, split PDF files, and discover tips for getting the best results. We'll also cover common use cases and best practices for PDF management.
How It Works
Our PDF merger and splitter uses PDF-lib, a powerful JavaScript library that processes PDFs entirely in your browser. When merging, the tool combines multiple PDF documents into a single file, preserving all pages, formatting, and metadata. When splitting, it extracts each page as a separate PDF file.
All processing happens locally in your browser, which means your PDF files never leave your device. This ensures complete privacy and security for sensitive documents. The tool maintains PDF quality and formatting throughout the process.
You can reorder PDFs before merging by dragging and dropping files, and when splitting, all pages are extracted and can be downloaded as individual files or as a ZIP archive for convenience.
How to Merge PDF Files
Step 1: Access the Tool
Navigate to our PDF Merger / Splitter page and select the "Merge" mode.
Step 2: Upload PDF Files
Click the upload area or drag and drop multiple PDF files. You can upload several PDFs at once. Each file should be under 50MB in size.
The uploaded files will appear in a list, showing their names and sizes. You can see the order in which they will be merged.
Step 3: Reorder Files (Optional)
If needed, drag and drop the files to reorder them. The merged PDF will follow this order, with pages from the first file appearing first, followed by pages from the second file, and so on.
Step 4: Merge PDFs
Click the "Merge PDFs" button to start processing. The tool will combine all uploaded PDFs into a single document. This process typically takes just a few seconds.
Once processing is complete, you'll see a preview or download option for the merged PDF.
Step 5: Download Merged PDF
Click the download button to save the merged PDF to your device. The merged file will contain all pages from all uploaded PDFs in the order you specified.
How to Split PDF Files
Step 1: Select Split Mode
Navigate to our PDF Merger / Splitter page and select the "Split" mode.
Step 2: Upload PDF File
Click the upload area or drag and drop your PDF file. The file should be under 50MB in size. The tool will analyze the PDF and show you how many pages it contains.
Step 3: Split PDF
Click the "Split PDF" button to start processing. The tool will extract each page from your PDF and create separate PDF files for each page.
Processing time depends on the number of pages in your PDF, but typically completes in just a few seconds.
Step 4: Download Split PDFs
Once splitting is complete, you can download all split PDFs as a ZIP file. The ZIP will contain individual PDF files, one for each page, named sequentially (page-1.pdf, page-2.pdf, etc.).
Tips for Best Results
- Check file sizes: Ensure each PDF file is under 50MB for optimal performance. Larger files may take longer to process.
- Verify page order: When merging, double-check the order of files before merging to ensure pages appear in the correct sequence.
- Organize before merging: Name your PDF files descriptively so you can easily identify and order them when merging.
- Review split results: After splitting, verify that all pages were extracted correctly by checking the number of files in the ZIP.
- Keep originals: Always keep backup copies of your original PDFs before merging or splitting, in case you need to make changes.
