Why Merge PDFs?
There are plenty of reasons you might need to combine multiple PDF files into a single document. Maybe you scanned a contract one page at a time and need to stitch the pages together. Or you have separate reports from different departments that need to go out as one unified file. Teachers combine worksheets, lawyers merge exhibits, and freelancers pull invoices into a single billing package.
Whatever the reason, merging PDFs should be quick and painless. You should not have to install desktop software, create an account, or upload sensitive documents to someone else's server.
How to Merge PDFs with PDFTaco
Here is how to combine your PDF files using the free Merge PDFs tool on PDFTaco:
- Go to the Merge tool — Head to pdftaco.com/tools/merge.
- Drop your files — Drag and drop your PDF files onto the page, or click to browse and select them from your computer. You can add as many files as you need.
- Reorder if needed — Drag the file cards to rearrange them in the order you want them to appear in the final document.
- Click Merge — Hit the merge button and PDFTaco will combine everything into a single PDF in seconds.
- Download your file — Your merged PDF is ready to download immediately.
The entire process happens right in your browser. Your files never leave your device — they are not uploaded to any server. This means your documents stay completely private, and the tool works even if you are offline.
Tips for Merging PDFs
- File order matters. Make sure you arrange the files in the sequence you want before merging. It is much easier to reorder before combining than to rearrange pages after.
- No practical file size limit. Since everything runs locally in your browser, there is no arbitrary upload limit. Reasonable files (dozens of pages, typical document sizes) merge without any issues.
- Works on any device. PDFTaco runs in any modern browser — Chrome, Firefox, Safari, Edge — on desktop, tablet, or phone.
- Merge different types. You can combine PDFs that have different page sizes, orientations, or layouts. The merged file preserves each page exactly as it was.
When to Merge vs. Other Approaches
Merging is the right choice when you want to combine entire documents end to end. If you only need specific pages from each file, consider using the Split tool first to extract the pages you want, then merge the results. If you need to rearrange individual pages from a single PDF, the Reorder Pages tool might be a better fit.
PDFTaco's merge tool is completely free, with no watermarks, no page limits, and no sign-up required. Give it a try the next time you need to combine PDFs.
