Combine your PDF files into one — then mark up, stamp, sign, add cover sheets, watermarks and page numbers. Download and print, all from your device. Your files never leave your device.
No. The binder runs entirely in your browser. Your PDFs are read and assembled on your own device and never leave it — no upload, no server copy, nothing to delete afterwards. You can watch it work with your connection switched off.
Yes. Everything on this page is free — merge, reorder, rotate, mark up, stamp, sign, cover sheets, photo pages, watermarks, page numbers, extract, search, compress, download and print. No account, no forced watermark. Inside Muthari OS the same binder also saves drafts automatically while you work and shares packs by a link with a download record.
No fixed limit — your own device does the work, so big drawing sets are bounded only by your browser’s memory. A few hundred pages bind comfortably on a normal laptop.
Download it, then use Muthari Transfer — free sending up to 500 MB per file, no account for the recipient, and a download record on the link.
