PDFNoob vs PrepAI

PDFNoob is a browser-based suite for editing, compressing, converting, and managing PDF files. Its editor can add or change text, insert images and signatures, fill forms, and add, remove, or reorder pages. The site also lists tools for conversion, compression, OCR, summarization, question generation, signing, metadata editing, and page management. The editor is free without sign-up and does not add a watermark, but its upload limit is 10 MB per file. The free Merge PDF tool accepts up to 20 files and 100 MB total. PDFNoob says files on the editor and merge pages are deleted within one hour; its privacy policy says server-processed files are removed after the requested operation. Many operations run locally in the browser. The service says it does not index uploaded contents or use them to train AI, and that files are encrypted in transit with HTTPS. On a phone, users can choose files from Photos, Files, iCloud, or Google Drive. It is listed for Android, iOS, macOS, web, and Windows. The free tier is described as covering most personal and small-business needs.
