Questions and answers
How many files can I combine at once?
Up to 110 files in one batch. If you have more, combine them in two rounds and then join the two results.
Which file types work?
PDF, JPG, PNG and HEIC. You can mix them in the same list.
Are my files uploaded anywhere?
No. The page reads your files in your browser, builds the PDF there, and gives it back as a download. We never receive or store the files.
What is the difference between combining and converting?
Combining joins many files into one PDF. Converting turns each image into its own PDF. The main page and the photos page combine files. The PNG and HEIC pages convert them.
Can I change the order of the files?
Yes. Drag a file up or down, or use the arrow buttons next to it. The PDF follows the list from top to bottom.
Does it work on a phone?
The web page works in mobile browsers such as Safari and Chrome. The Chrome extension is for desktop Chrome.
Will my photos lose quality?
PNG images and most JPG photos go into the PDF as they are. Photos that need rotating are re-saved at high quality, and HEIC photos are converted to JPG first, so a small change is possible.
Why did my PDF get rejected?
Password-protected PDFs can't be combined. Remove the password in the program that made the file, then add it again. A damaged file is rejected too.
How do I install the extension?
Use the Add to Chrome button on this page, click Add to Chrome in the Chrome Web Store, then pin CombinePDF from the puzzle-piece menu in your toolbar.
