Frequently Asked Questions (FAQ)
Yes, completely safe. Our PDF combiner processes all files locally in your browser using JavaScript. Your PDFs never leave your computer, are not uploaded to any server, and are not stored anywhere. Once you close the browser tab, all temporary data is cleared.
You can combine PDFs up to 50MB each. There’s no limit to the total size of the combined PDF or the number of files you can combine. However, for performance reasons with very large files, we recommend using the compression option to reduce file size.
Our current tool combines entire PDF files in the order you specify. For rearranging pages within a PDF, you would need a PDF splitter and combiner tool. However, you can achieve similar results by splitting a PDF into individual pages first, then recombining them in your desired order.
Yes, formatting and quality are preserved. When you select “No Compression,” the combined PDF maintains the exact quality of the original files. With compression options, we use intelligent algorithms that minimize quality loss while reducing file size.
When combining PDFs, internal links within each PDF are preserved, but bookmarks from individual PDFs may not carry over to the combined document. For complex PDFs with extensive bookmarks and cross-references, dedicated desktop PDF software may provide more advanced options.
