Questions & answers

Frequently asked

Can I reorder pages from different files?

You can reorder the files themselves before merging. Page-level reordering within a file is not supported. Use a dedicated PDF editor for that.

Is there a limit on how many files I can merge?

No enforced limit. The practical limit is browser memory, merging very many large PDFs may slow down on low-memory devices.

Does PDF Merger upload my PDF or source file?

Your file is processed in your browser and is not uploaded.

What does PDF Merger create?

It creates one combined PDF. Files are merged in the order shown in the browser.

Can PDF Merger handle every PDF?

PDFs vary by structure, encryption, fonts, images, and metadata. Keep the original file and review the generated output before using it.
