PurePDF HQ

PurePDF HQ is a set of free PDF tools that work entirely in your browser: merge, split, compress, rotate, reorder and delete pages. The work runs on your own device with qpdf compiled to WebAssembly, so your files are never uploaded to a server. You can check this in your browser's Network tab while a tool runs. Compress can shrink a file to a size you type, with ready pages for 200 KB and 100 KB upload limits. If a file can't get that small, it says so and shows the smallest size it reached. Merge and split keep bookmarks, links and form fields where they apply. No account, no watermark, free.
