Frequently Asked Questions

Is my document uploaded to a database?

No, never. This tool is completely private, and your files and data never leave your device. All PDF reading, copying, and page combinations run locally on your device with zero server uploads.

Can I merge files other than PDFs?

No. This specific tool is dedicated to merging standard PDF documents. If you have images (JPEG, PNG, WebP) you want to convert or combine into a PDF, you can use our Image to PDF Converter tool.

Why did the merge process fail?

Merging will fail if one or more selected PDF files are encrypted or password-protected, as the browser-based library cannot read them without a decryption key. Make sure your files are unlocked before uploading.

Is there a limit on the number of PDFs I can merge?

No, there are no artificial limits. You can select and combine as many PDF files as you need. Keep in mind that processing a high number of heavy files depends on your device's memory capacity.

Does merging files affect their original quality?

No. Our tool copies pages directly from source documents into the output document without re-compressing or rasterizing them. Text formatting, vectors, metadata, and images remain identical.

Is there any signup or login required?

No. You do not need to create an account, enter email addresses, or log in to use the PDF Merger. It is completely free to use with no registrations and unlimited document compiling.

Can I merge PDF documents with different page orientations or sizes?

Yes! You can merge documents containing any mix of Portrait and Landscape pages, as well as different page dimensions (like A4, Letter, and Legal). Each page preserves its individual layout in the combined PDF.
