Questions
Is there a limit to how many files I can merge?
No. The only limit is your device’s memory, and hundreds of pages are fine on an ordinary laptop or phone.
Will merging reduce the quality?
No. Pages are copied as they are, and nothing is re-compressed.
Can I change the order after adding the files?
Yes. Drag the cards, use the arrow buttons, or sort A–Z. To reorder individual pages, use Organize pages.
Are my files uploaded?
No. Merge PDF runs entirely in your browser, so your files never leave your device. It even works offline once the page has loaded.
Is it free?
Yes, completely: no limits, no watermark, no sign-up and no ads.
