FAQ
Are files uploaded, or is quality lost?
Files are processed only in your current browser. Pages are copied as PDF pages with their original text and images, not turned into pictures first. Your original file is not overwritten.
Are encrypted files, forms and signatures supported?
Encrypted PDFs, interactive forms and digitally signed files are not supported yet; export a regular PDF copy from the original software first. Bookmarks and links between pages are not guaranteed to survive, so check the result for important documents.
How many pages can it handle?
Each input PDF can have 1–100 pages and up to 40 MB; each export can contain up to 100 pages in total, with up to 100 MB of output. You can merge up to 20 files with 100 MB of input in total. Files are kept only in the current page session, so choose them again after a refresh.
