Frequently asked questions
Does the order matter, and can I change it?
It matters, and yes. The files go in the order you pick them, and you can drag them into a different order before you start. Each file keeps its own page size, so mixing an A4 report with a letter-size scan gives you a PDF whose pages are not all the same shape.
Does anything about the file change?
Only what you asked for. The text stays text and stays selectable, the pages keep their size, and nothing is flattened into an image. The one exception is compression, which is meant to change the file and says so.
Is anything uploaded?
No. The PDF engine runs inside your browser, so the files are read on your own device and never leave it. There is no account, no queue and no upload.
Is it really free?
Yes. No sign-up, no trial, no watermark and no cap on how many files you put through it. The site is paid for by ads.
