Original Summary

Every PDF site I tried uploads your document to a server just to rotate a page. Mine doesn't: everything runs in your browser, so you can load the page, disconnect, and keep working. https://robinpdf.com Yes, there are a hundred PDF sites. This one has 33 tools — merge, split, compress, convert to Word or Excel, OCR, sign, redact — with no account, no email, no queue, and no size limit beyond what your own machine can handle. The claim is easy to check, and that's the whole point: open any tool, turn off your Wi-Fi, and use it. It still works. Or keep the network tab open while you process a file and watch that nothing leaves. The three ways to check it are written down here: https://robinpdf.com/verify/ A few honest bits before anyone asks: - It's free and it runs on ads. I'd rather say it than have you find out. - It's not open source. What you can verify is the part that matters: the file stays on your device. - It's built on pdf.js and pdf-lib, like most of these. The work is in the awkward cases — bank and insurance PDFs that open fine but forbid editing, which most sites reject; scans that come out of "Print to PDF" as thousands of tiny tiles; JPEG 2000 images; checking a signature and being told whether what changed afterwards was just the other person signing. - The tool that signs with a real certificate loads no third-party script at all, ads included, because your private key sits in that page's memory while you use it. Almost everything added lately came from people telling me what broke: batch compression, an Android file picker that kept opening Google Photos instead of the gallery, and merging a folder of invoices into one PDF per day by reading the numbering in the file names. So: what's missing, what's broken?   submitted by   /u/robao [link]   [comments]
