The core promise is privacy and convenience: you open a tool, drop in a PDF or image, and for the majority of operations the file never leaves your device because the processing happens inside the browser. Common jobs like merging, splitting, compressing, rotating, converting between PDF and Word, JPG, Markdown, or extracting tables are grouped by intent — combine files, reduce size, make PDFs editable, protect a document — so it is easy to jump straight to the task you need. Beyond the free browser tools, iTextMaster exposes a developer-facing PDF API. Signed-in users receive a monthly credit allowance, and paid credits cover backend jobs such as HTML-to-PDF rendering, invoice generation, webpage capture and batched merges. The site states that failed processing attempts are refunded automatically, and server-side tools are flagged before you submit data, which is a useful transparency detail for teams handling sensitive documents. The service is entirely web-based — there is no software install required, though a Chrome extension and a keyboard-driven workbench view are offered for frequent users. It is a pragmatic choice for individuals and small teams who want quick PDF fixes without accounts or upload risk, and for developers who would rather call an API than build PDF infrastructure themselves. **Pricing & Plans:** Website PDF tools are free to use, with most processing done locally in the browser. The PDF API uses a credit system: every signed-in user gets 100 free API Credits per month, 1,000 Credits equal $1, and basic API operations start at 1 Credit. Failed attempts are refunded automatically. Check the official pricing page for current details. - **135+ PDF tools:** A deep catalog covering merge, split, compress, linearize, OCR, encrypt, redact, flatten, metadata removal, format conversion and table extraction. - **Local browser processing:** Most file tools run entirely in your browser, so everyday PDF work does not require uploading your document to a server. - **Credits-based PDF API:** Backend endpoints for merge, split, HTML-to-PDF, webpage-to-PDF, invoice generation, redaction and OCR, billed through monthly credits. - **Clear server-path disclosure:** Tools that need server rendering, URL fetching or API processing state that clearly before you submit any data. - **Guided workflows:** Task-oriented routes and guides group tools by intent, and a searchable workbench plus Chrome extension speed up repeated jobs. **Strengths:** Large single-purpose tool catalog, so you rarely need a second site; Browser-first processing keeps most sensitive files on your device; Transparent labeling of which tasks run server-side; Free monthly API credits make it easy to prototype automation **Limitations:** No desktop or mobile app; everything depends on the browser; API use requires buying credits once the free monthly allowance runs out; With 135+ tools the catalog can feel overwhelming at first [Profile (Markdown)](https://openaitools.app/tool/itextmaster.md) ## Knowt Knowt is a study platform built around flashcards and AI study tools, and it markets itself as the leading free Quizlet alternative. Its pitch is consolidation: rather than juggling several apps, students upload their class materials once and get flashcards, notes, summaries, and practice tests generated in one place. Importing existing Quizlet sets takes a couple of clicks, including images and formatting. The AI layer is powered by Kai, an assistant that works across PDFs, slides, images, videos, and live lecture recordings. Uploading files produces notes, flashcards, and quizzes automatically, and Kai can also answer questions about your materials and explain why a practice answer was wrong. An Exam Predictor and Planner builds a study schedule from uploaded course files, while Voice Tutoring & Podcasts let students be quizzed aloud or turn notes into audio for studying on the go. Knowt is free to use for core studying, with unlimited learn mode and free practice tests.
