PDFNoob vs PDFQuiz

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.

PDFQuiz uses AI to turn PDFs and other uploaded documents into interactive quizzes. Its listed 16 upload formats include office documents, images, and text formats; six question types range from single choice and matching to open ended. OCR can read scanned pages and photos. Users can take quizzes online, study questions as flashcards, download quizzes and results as PDFs, and export quizzes to Anki depending on plan. Paid plans can generate quizzes in a chosen output language from a list of more than 180. The free options allow a 10-question quiz without an account, or three quizzes of up to 10 questions each for a free account; account quizzes can use documents of up to 20 pages. Paid tiers add differing character limits and features such as invitation links, timers, editing, API access, and Zapier integration. The Elite plan lists up to 1,500 quiz invitations per month, API access, and Zapier integration. Uploaded files, quizzes, and results are retained while an account exists, though users can request deletion. The listed starting price is $5/mo (annual).
