Merging multiple PDF files into one document is one of the most common PDF tasks. Whether you're combining reports, organizing receipts, or compiling research papers, PDFit makes it effortless — right in your browser.
Why Merge PDFs?
Instead of sending separate files, combining them into a single PDF makes sharing easier and keeps your documents organized. Here are a few common scenarios:
- Combining multiple expense receipts into one report
- Merging chapters of a research paper
- Joining signed documents with cover pages
- Consolidating meeting notes from different sources
Step 1: Upload Your Files
Head over to the Merge PDF tool and drag your files into the upload area. You can also click "Choose Files" to browse your computer. PDFit supports merging up to 20 files at once.
Tip: The order in which you upload files determines their order in the final document. Drag and drop to rearrange them before merging.
Step 2: Arrange the Order
Once uploaded, you'll see thumbnail previews of each page. Simply drag and drop to reorder them. You can also delete pages you don't need by clicking the trash icon.
Step 3: Download Your Merged PDF
Click the "Merge PDF" button and your combined file will be ready in seconds. The merged document downloads directly to your device — no server upload, no waiting.
