So I built a simple alternative:</p> <p>👉 <a href="https://nouploadpdf.org" rel="noopener noreferrer">https://nouploadpdf.org</a></p> <h2> 💡What’s different? </h2> <p>Everything runs completely in your browser.</p> <ul> <li>No file upload</li> <li>No server processing</li> <li>No storage Your files never leave your device.</li> </ul> <h2> 🛠️ How it works (high level) </h2> <p>Instead of sending files to a backend:</p> <ul> <li>Files are processed locally in the browser</li> <li>Operations happen in memory</li> <li>Output is generated instantly</li> </ul> <p>This makes it faster for small tasks, completely private. People upload resumes, contracts, financial documents etc. to random PDF tools online which is a risky action. This approach removes that risk entirely.</p> <h2> ⚖️ Trade-offs </h2> <p>There are some limitations:</p> <ul> <li>Performance depends on your device</li> <li>Large files can be slower</li> <li>Browser memory limits apply But for most everyday use cases, it works well.</li> </ul> <h2> 🙌 Looking for feedback </h2> <p>If you’re a developer or frequent PDF user, try it- <a href="https://nouploadpdf.org" rel="noopener noreferrer">https://nouploadpdf.org</a>.
