PDF Platform is an all-in-one online toolkit for PDFs and images. Merge, split, compress, convert (Word, Excel, PowerPoint, JPG/PNG), rotate, reorder and delete pages, crop, add watermarks and page numbers, protect or unlock with a password, repair damaged files, and extract embedded images โ€” 35+ tools in one place.

What sets it apart is privacy. Many everyday tools โ€” merge, split, rotate, organize, image-to-PDF, crop, image compression and document scanning โ€” run entirely in your browser. Your files never leave your device and no account is required; you get the result in seconds.

For heavier work, PDF Platform adds Office-format conversions, OCR that turns scans into searchable, selectable text, and a full set of AI features: summarize long documents, chat with a PDF to ask questions, translate, extract structured data to CSV/JSON, compare two PDFs, and redact sensitive information. These come with affordable paid plans, while the core client-side tools stay free.

It works on desktop and mobile and installs as a Progressive Web App (PWA) for one-tap access from your home screen โ€” no app store needed. On supported browsers you can even open PDFs directly with it.

Highlights: - 35+ PDF and image tools in one clean workspace - On-device processing for real privacy (no upload, no sign-up for free tools) - Convert to and from Word, Excel, PowerPoint and images - AI: summarize, chat, translate, extract, compare, redact - Document scanner (camera to PDF) + OCR / searchable PDF - Compress PDFs and images to shrink file size for email and web - Installable PWA that works on desktop and mobile - Free tier plus simple, affordable upgrades

Whether you need a quick one-off edit or a daily professional PDF workflow, PDF Platform keeps it fast, private and simple.

Questions & Answers

As answered by people managing CodeSandbox and PDFPlatform.app.

What makes your product unique?

PDFPlatform.app's answer:

Most everyday tools run entirely in your browser, so your files never leave your device and no account is needed. It combines 35+ PDF and image tools with AI (summarize, chat, translate, extract, compare, redact), OCR, and a camera document scanner in a single installable web app โ€” privacy-first, no watermarks, free to start.

Which are the primary technologies used for building your product?

PDFPlatform.app's answer:

React, TypeScript, Vite and Tailwind CSS on the frontend (as an installable PWA with a service worker for offline use); Node.js/Express with Prisma for auth and subscriptions; Python/FastAPI with PyMuPDF, pikepdf and pypdf for the PDF engine; client-side WebAssembly for on-device processing โ€” pdf-lib, PDF.js, Tesseract.js (OCR) and OpenCV.js (document scanner); PostgreSQL; iyzico for payments; and Anthropic Claude for AI features.

Why should a person choose your product over its competitors?

PDFPlatform.app's answer:

Unlike tools that upload your files to a server, hide features behind sign-ups, or stamp watermarks on the output, PDFPlatform.app processes files on your device wherever possible, keeps core tools free with no account, and never adds watermarks. You also get AI features and OCR that most free PDF sites don't offer, all in one clean, installable app that works on desktop and mobile.

How would you describe the primary audience of your product?

PDFPlatform.app's answer:

Anyone who needs fast, private PDF and image tasks without installing software โ€” students, freelancers, and professionals in accounting, legal, HR and admin, as well as privacy-conscious users and mobile-first users who want quick edits and conversions on the go. Also small businesses that need everyday document tools without enterprise pricing.

What's the story behind your product?

PDFPlatform.app's answer:

Built by NB Global Studio out of frustration with PDF tools that upload your documents, force sign-ups, add watermarks, or require paid desktop software. The goal was a single, honest toolkit that runs in the browser, processes files on-device for privacy, and stays free for everyday tasks โ€” with AI and OCR available for heavier work.

  • Thankful for CodeSandbox
    I am thankful for a platform like CodeSandbox because it allows me to offload majority of the processing power and memory resources to the cloud. With a local VS Code installed, I can tunnel in via a remote connection to work on my projects, tinker, or do a deep-dive on certain topics; all while ensuring that the RPi 4 still has sufficient resources left to run other things in the background. - Source: dev.to / over 1 year ago
