How to Merge PDF Files Online for Free
Merging PDFs is useful when an application, invoice package, report, or client file is spread across several documents. PDF Mixo combines the files in your browser so you can review the order before downloading one finished PDF.
Open Merge PDFMerge PDFs in three steps
Open the Merge PDF tool and choose every PDF that belongs in the final document. Arrange the files and pages in the sequence the reader should see them, then create and download the combined PDF.
- Use clear filenames before you begin.
- Place cover letters and index pages first.
- Open the downloaded PDF and check the first and last page.
How to choose the right page order
For applications, put the main form first and supporting records afterward. For business reports, start with the title page or executive summary. If a file contains an unwanted page, remove it before the final export so the combined document remains easy to review.
- Keep portrait and landscape pages readable.
- Check that no page is duplicated.
- Retain the original source files as a backup.
Privacy when combining documents
The standard PDF Mixo merge workflow runs locally in your browser. Your selected files are processed on the device for this operation. Avoid sharing the result until you have checked that it contains only the pages and personal information the recipient needs.
