Every free PDF site has the same catch: upload your file, wait in a queue, hope they delete it. OxygenPDF skips the upload entirely.

Merge, compress, sign, convert, and edit all run inside your browser tab, on your machine. Files never leave your device, so there's no queue and nothing to wait for. Drop a PDF, pick a tool, save. Usually done before you've moved the mouse.

StackBlitz features and specs

  • Speed
    StackBlitz is known for its quick load times and fast editing capabilities, making it ideal for rapid development and testing.
  • Ease of Use
    The interface is intuitive and user-friendly, allowing developers to get started quickly without a steep learning curve.
  • Zero-Setup
    Users can write, compile, and run code directly in the browser without any setup or configuration required.
  • Integrations
    StackBlitz integrates seamlessly with GitHub, allowing for easy import and export of repositories.
  • WebContainers
    StackBlitz uses WebContainers to run Node.js applications in the browser, providing a near-native development experience.
  • Collaboration
    Real-time collaboration features allow multiple users to work on the same project simultaneously, similar to Google Docs.

Possible disadvantages of StackBlitz

  • Limited Plugins
    Unlike traditional IDEs like VSCode or IntelliJ, StackBlitz has a limited ecosystem of plugins and extensions.
  • Online Dependency
    StackBlitz requires an internet connection to function, which can be a limitation for developers who need to work offline.
  • Performance
    For very large projects or those requiring extensive computational resources, performance may degrade compared to local development environments.
  • Mobile Accessibility
    While StackBlitz is accessible on mobile devices, the user experience is not as optimized as it is on desktop browsers.
  • Limited Framework Support
    Although StackBlitz supports many popular frameworks, it doesn't support all frameworks or versions, which could be limiting for some projects.
  • Storage and Persistence
    Files and data are stored in the cloud, which might raise concerns around data privacy and persistence for some users.

OxygenPDF features and specs

  • Simple and focused tool
    OxygenPDF provides a straightforward, focused PDF editing experience without overwhelming users with unnecessary features, making it accessible for basic PDF tasks.
  • Web-based accessibility
    As an online PDF tool, OxygenPDF can be accessed from any device with a web browser without requiring software installation, offering convenience and cross-platform compatibility.
  • Quick PDF operations
    The tool allows users to perform common PDF operations such as merging, splitting, and converting files relatively quickly without a steep learning curve.
  • No account required for basic use
    Users can often perform basic PDF operations without needing to create an account or sign up, reducing friction for one-time or occasional use.
  • Free tier availability
    OxygenPDF offers free functionality for basic PDF tasks, making it a cost-effective option for users who only need occasional PDF editing or conversion.

Questions & Answers

As answered by people managing StackBlitz and OxygenPDF.

Who are some of the biggest customers of your product?

OxygenPDF's answer:

  • SmallPDF
  • BentoPDF
  • ILovePDF

What makes your product unique?

OxygenPDF's answer:

Your files never leave your device. Every one of the 60+ tools runs inside your browser, so there's no upload, no queue, no server holding your documents. That also makes it fast, results show up almost instantly because nothing has to travel anywhere. And it's a one-time $9 for Pro, not a subscription.

Why should a person choose your product over its competitors?

OxygenPDF's answer:

Adobe Acrobat runs $240 a year and Smallpdf $108, and both upload your files to their cloud. OxygenPDF is $9 paid once, works offline, and never sends a single byte off your machine. You also get 60+ tools instead of the usual 20, and no account or sign-up to use any of them.

How would you describe the primary audience of your product?

OxygenPDF's answer:

People who handle PDFs regularly and care where their files go. Freelancers, lawyers, accountants, healthcare and admin staff, anyone dealing with contracts, invoices, or private records. Also the privacy-conscious crowd who'd rather not upload personal documents to a random website, and people tired of subscriptions for basic tools.

What's the story behind your product?

OxygenPDF's answer:

I got tired of uploading important documents to random sites just to delete one page. Every free PDF tool wanted my email, slapped on a watermark, or sent my private files to a server I had no reason to trust. So I built OxygenPDF, solo, on nights and weekends. No investors, no data play. I built it because I needed it and figured other people did too.

Which are the primary technologies used for building your product?

OxygenPDF's answer:

The browser-based engine (WebAssembly for the PDF processing), the frontend framework (React/Next.js or similar), and the on-device AI for the Chat feature.

  1. Has almost everything I need

    I've started using this as my main IDE for new projects when I'm trying things out. If it keeps getting better at the rate it has been, it'll be even better than coding locally.

    ๐Ÿ‘ Pros:    Easy to get started and operate|Fast|Supports common extensions|Works with most npm packages

All applications created on StackBlitz also get deployed automatically on their servers! So, this Angular toy app I just created is hosted automatically on https://angular-yvyi2j.stackblitz.io/.

  • RS-X: Framework-agnostic reactive state and expressions for JavaScript/TS
    Managing reactive state and dependent computations in JavaScript can get complex, especially when combining asynchronous and synchronous data. RS-X is a library that allows you to bind expressions to plain objects and makes the parts of the model used by those expressions fully reactive. Dependent computations automatically update when the underlying data changes. RS-X is framework-agnostic. While it can drive UI... - Source: Hacker News / 5 months ago
  • Show HN: I combine Htmx, LiveView and SolidJS for interactive server components
    I like htmx, LiveView, React and Solid. They are great at different points, so I try to combine them in Solv (Stateless Offline-capable LiveView) and write a prototype to show the benefits. Solv's main idea is that stateless servers keep client's state in a volatile cache. It enables server components that are also interactive, which is best of both worlds between LiveView and htmx. Then fine-grained reactivity is... - Source: Hacker News / 8 months ago
