PDF Kit by implements

PDF Kit is a set of fourteen PDF tools that run in your browser: merge, split, organize and rotate pages, add page numbers, a watermark or a signature, add or remove a password, edit a document's details and shrink scans. Files are opened and rewritten on your own device with pdf-lib and pdf.js, and never uploaded to a server. It works offline once opened, even in airplane mode, and installs to your iPhone or Android home screen like an app. Merging up to 3 PDFs and splitting a PDF are free, with no account. The rest comes with implements, one subscription for many small web tools ($4.99 a month or $49.99 a year), built and run by Rootless Agency.
