Frequently Asked Questions
How does the PDF merging tool work?
Our tool allows you to select multiple individual PDF documents from your computer, arrange them in your preferred order, and securely combine them into a single, seamless PDF file for easier sharing and printing.
Is it safe to merge confidential legal or medical PDFs online?
Yes, because our PDF merging engine operates entirely client-side using advanced JavaScript libraries. Your sensitive PDF documents are processed locally in your browser memory and never uploaded to our servers.
Can I rearrange the order of the PDF files before merging?
Absolutely. Once you upload the files, you can use our intuitive drag-and-drop interface to reorder the documents exactly how you want them to appear in the final merged file.
Will merging PDFs degrade the quality of the text or images?
No, our merging process concatenates the binary PDF structures losslessly. The original text formatting, vector graphics, high-resolution images, and hyperlinks will remain exactly as they were in the source files.
Is there a limit to how many PDFs I can merge at once?
While there is no hard software limit, your web browser's available memory dictates performance. We recommend merging batches of 10 to 20 files at a time to ensure smooth processing.
