Frequently Asked Questions

Can I merge password-protected PDFs?

Yes! Our PDF merger supports password-protected PDFs. When you select an encrypted PDF, you'll be prompted to enter the password. The merged output will not be password-protected by default, giving you full control over the final file.

Is there a file size limit?

You can merge PDF files up to 100MB each, with a total combined size of 500MB. For larger files, we recommend splitting them into smaller batches for faster processing. Most typical documents (reports, contracts, presentations) are well under these limits.

Will merging PDFs reduce quality?

No, absolutely not! Our PDF merger maintains 100% of the original quality. All images, text, formatting, fonts, and colors are preserved exactly as they appear in the source files. The merged PDF is identical in quality to the originals.

How many PDF files can I merge at once?

There's no limit on the number of files! You can merge 2, 10, 50, or even hundreds of PDF files in a single operation. The only constraint is the total file size (500MB), which typically allows for dozens of documents.

Can I select specific pages from each PDF?

Absolutely! For each PDF file you select, you can specify which pages to include using ranges like "1-5, 10-15" or specific pages like "1, 3, 7". Leave the field blank to include all pages from that file. This is perfect when you only need certain pages from larger documents.

Is my data safe? Are PDFs uploaded to a server?

Your PDFs never leave your computer. All merging happens 100% in your browser using JavaScript. There are no uploads, no cloud storage, and no server processing. This makes our tool completely safe for confidential documents like contracts, financial statements, or medical records.

What PDF versions are supported?

Our tool supports all PDF versions from PDF 1.0 through PDF 2.0, including password-protected PDFs, PDFs with forms, images, and complex formatting. The output is a standard PDF file compatible with all PDF readers including Adobe Acrobat, Preview, Chrome, and mobile apps.

Do I need to install any software?

No installation required! This is a web-based tool that works directly in your browser. Just visit this page, select your PDF files, and merge them instantly. It works on Windows, Mac, Linux, and even mobile devices with any modern browser.
