Frequently asked questions
Is there a limit on how many PDFs I can merge?
You can merge up to 50 files at once, each up to 100 MB. Very large combined documents may be slow on phones or older computers.
Will merging change the quality of my PDFs?
No. Pages are copied as they are — text, images and vector graphics are not re-compressed.
Are my files uploaded?
No. Merging happens on your device using JavaScript. Your files are never sent to our servers.
