PDFPuddle

PDFPuddle is a browser-based AI PDF toolkit that lets you merge, split, compress, convert, edit, sign, and redact PDFs without uploading your files to a server. It bundles 32 tools and runs entirely client-side in your browser, so your documents never leave your device. PDF operations include merge, split, compress, organize, rotate, crop, resize, repair, unlock, protect, add page numbers, scan, OCR, compare, and redact. It converts PDFs to and from Word, PowerPoint, Excel, JPG, and HTML, and adds enhancements like digital signatures, watermarks, PDF/A conversion, plus AI summarization and translation. There is native editing for PDF, Word, and PowerPoint files. PDFPuddle is aimed at anyone who handles everyday document tasks and cares about privacy, since there are no server uploads, signups, or subscriptions required. The trade-off of client-side processing is that very large files or batch jobs depend on your own device's performance rather than a server.
