Frequently Asked Questions

Common questions about Merge PDF and client-side processing.

Can I merge multiple PDF files at once?

Yes. You can select two or more PDF files and combine them into a single continuous document.

Can I change the order of files before merging?

Yes. Use the Move Up and Move Down buttons to arrange your documents in the exact order you want them assembled.

Are my PDF documents uploaded to any server?

No. All PDF parsing and page copying runs 100% locally in your browser memory. Your confidential documents never leave your machine.

Does merging reduce PDF or text quality?

No. Pages are copied as native PDF vector elements without rasterizing, screenshotting, or compressing your text and graphics.

Can I merge password-protected (encrypted) PDFs?

Encrypted PDFs must be unlocked before merging. FILEMORPH cannot merge password-protected files without authorization.

Is there a limit on file size or page count?

There are no artificial daily limits or paywalls. You can merge documents up to available device memory.
