Docqify merges JPG, PNG, WEBP, HEIC, BMP and GIF into a single PDF, and does the entire conversion inside your browser using your device's own processor. Nothing is uploaded, because there is no server to upload to.

It can add a searchable text layer using OCR that also runs locally, so text inside photographed documents becomes findable. You can reorder, rotate and crop pages, set page size and margins, add watermarks, headers and page numbers, and password-protect the result.

There is no sign-up, no watermark on output, and no limit on file count or size. It keeps working offline once loaded.

Possible disadvantages of CodePen

  • Limited Offline Functionality
    Since CodePen is primarily an online tool, it requires an internet connection for most of its features to work, limiting its usefulness in offline environments.
  • Performance Constraints
    Complex or resource-intensive projects may not perform as well on CodePen as they would in a full-fledged local development environment.
  • Subscription Costs
    While many features are free, advanced functionalities and additional storage options require a paid subscription, which may not be ideal for all users.
  • Limited Backend Capabilities
    CodePen is primarily designed for front-end development, so it offers limited support for backend technologies, making it less suitable for full-stack or server-side development.
  • Dependency Management
    Managing dependencies and libraries can be cumbersome compared to local development environments which have better tools for this purpose, like npm.
  • Security Concerns
    Sharing projects with the public can expose your code and assets to unauthorized use, posing potential intellectual property and security risks.

Questions & Answers

As answered by people managing CodePen and Docqify.app.

What's the story behind your product?

Docqify.app's answer:

I kept needing to turn a stack of phone photos into one PDF and every tool I found wanted me to upload them first. That felt wrong for documents with my ID on them, so I built one that doesn't. The hardest part was making HEIC work reliably on Android the common decoder library evaluates strings at runtime, which a strict CSP blocks, so it failed silently on mobile for a long time.

Which are the primary technologies used for building your product?

Docqify.app's answer:

Next.js and React with TypeScript. libheif compiled to WebAssembly for HEIC decoding, Tesseract.js for OCR, and pdf-lib to assemble the PDF. Decoding runs in a Web Worker pool, and a service worker caches the app shell so it works offline.

What makes your product unique?

Docqify.app's answer:

Docqify runs the entire conversion inside your browser. There is no server to upload to, so files never leave your device and that isn't just a promise, it's enforced by a Content Security Policy that makes the page structurally incapable of connecting to another origin. It also handles HEIC from iPhones and adds a searchable text layer using OCR that runs locally, both of which most free converters either skip or charge for.

Why should a person choose your product over its competitors?

Docqify.app's answer:

Most converters upload your files to their servers, add a watermark, cap how many files you can process, or ask you to sign up. Docqify does none of those. It's free, has no account, no watermark, and no file limits, and because the work happens locally it also keeps working with no internet connection once the page has loaded.

How would you describe the primary audience of your product?

Docqify.app's answer:

Students submitting assignments and applications, job seekers preparing documents, and anyone dealing with forms that require photos merged into a single PDF. It's also used by people who are simply uncomfortable uploading documents containing personal identification to a third-party server.
