About the Merge PDF

Combining several PDF files into one comes up constantly — merging separate scanned pages into a single document, combining a cover letter and resume into one file before submitting a job application, or assembling multiple chapters or reports into a single bound document for easier sharing and printing. Doing this without the right tool usually meant opening each file in a PDF editor and manually copying pages across, or resorting to a desktop application just for this one task.

This tool merges PDFs directly using a JavaScript PDF library running entirely in your browser. Upload your files in any order, and they'll be combined in the sequence they appear in the list, page-for-page, into a single new PDF file. The original page content, including text and embedded images, is preserved exactly as it appeared in the source files — this is a true document merge, not a re-scan or flattening of the content.

It's used constantly by job seekers combining application documents, students assembling multi-part assignments, professionals compiling reports from multiple contributors, and anyone who's ever needed to turn a folder of separate PDFs into one shareable file. Because the merge happens locally in your browser using client-side JavaScript, none of your documents are ever uploaded to a server in the process — an important distinction if the files contain any sensitive or confidential information.

Frequently asked questions

Is there a limit to how many PDFs I can merge?+
There's no fixed limit enforced by the tool; very large numbers of files or very large PDFs may simply take a bit longer to process depending on your device's memory.
Does merging affect the quality of the original pages?+
No, pages are copied directly from the source PDFs into the new merged file without any re-rendering or quality loss.
Can I change the order of the files before merging?+
Files are merged in the order they were added; remove and re-add files in your preferred sequence if you need to adjust the order.
Are my PDF files uploaded to a server during merging?+
No, the entire merge process happens locally in your browser using JavaScript. Your files are never uploaded, transmitted, or stored anywhere.
