For years.</p> <p>Then I realized something that changed how I think about every free online tool.</p> <h2> The hidden cost of "free" </h2> <p>Most online PDF tools are free. That's never been the problem.</p> <p>The problem is <strong>why</strong> they're free.</p> <p>Every time you upload a document to a random PDF website, your file is processed on servers you don't control. Owned by companies whose privacy policies nobody reads.</p> <p>That legal contract you're compressing. That financial statement you're splitting. That medical report you're editing.</p> <p><strong>Uploaded. Processed. Stored. Sometimes indefinitely.</strong></p> <p>You're not paying with money. You're paying with your data.</p> <h2> What I wanted vs what exists </h2> <div class="table-wrapper-paragraph"><table> <thead> <tr> <th>Online PDF Tools</th> <th>What I wanted</th> </tr> </thead> <tbody> <tr> <td>Files uploaded to third-party servers</td> <td>Files never leave my machine</td> </tr> <tr> <td>Privacy policies nobody reads</td> <td>No policy needed</td> </tr> <tr> <td>Stored indefinitely</td> <td>Nothing stored, ever</td> </tr> <tr> <td>Free with hidden costs</td> <td>Free. Full stop.</td> </tr> <tr> <td>Telemetry and tracking</td> <td>Zero telemetry</td> </tr> </tbody> </table></div> <p>I couldn't find a single tool that checked all the boxes on the right.</p> <p>So I built one.</p> <h2> LocalPDF Studio </h2> <p><strong>A complete offline PDF toolkit. No internet. No uploads. No compromise.</strong></p> <p>It runs entirely on your machine:</p> <ul> <li>No server</li> <li>No upload</li> <li>No account</li> <li>No tracking</li> <li>No telemetry</li> <li>No catch</li> </ul> <p>Free forever under AGPL-3.0.</p> <h2> What it can do </h2> <p><strong>Core operations:</strong></p> <ul> <li>Compress, merge, split, crop, and reorder PDFs</li> <li>Split pages vertically down the middle</li> <li>Extract and reorder specific pages</li> </ul> <p><strong>Conversion:</strong></p> <ul> <li>PDF to PDF/A (archival format)</li> <li>PDF to Markdown (GitHub-flavored)</li> <li>PDF pages to images</li> <li>Images to PDF</li> <li>Full OCR for scanned documents</li> </ul> <p><strong>Editing and annotation:</strong></p> <ul> <li>Add comments, highlights, drawings, and text</li> <li>Insert hand signatures</li> <li>Basic image editor</li> <li>Build fillable PDF forms (text fields, checkboxes, dropdowns)</li> <li>Flatten filled forms</li> </ul> <p><strong>Privacy and security:</strong></p> <ul> <li>Lock/unlock with passwords</li> <li>Redact sensitive content (permanently)</li> <li>Edit or remove metadata</li> <li>Convert to grayscale</li> </ul> <p><strong>Utilities:</strong></p> <ul> <li>Add page numbers automatically</li> <li>Add watermarks (text or image)</li> <li>Extract embedded images</li> <li>Presentation mode</li> <li>Multi-language UI (English, Bengali, Chinese, Japanese)</li> </ul> <h2> Who is this for? </h2> <ul> <li> <strong>Students</strong> - Uploading assignments to random websites</li> <li> <strong>Freelancers</strong> - Sending contracts to clients</li> <li> <strong>Small business owners</strong> - Handling financial documents</li> <li> <strong>Healthcare workers</strong> - Processing patient forms</li> <li> <strong>Legal professionals</strong> - Managing case files</li> <li> <strong>Privacy-conscious individuals</strong> - Anyone who values their data</li> </ul> <p>Also works in <strong>air-gapped, offline, or restricted environments</strong> with no internet connection required.</p> <h2> Download </h2> <ul> <li> <strong>Windows (10/11):</strong> <a href="https://alinur1.github.io/LocalPDF_Studio_Website/" rel="noopener noreferrer">Download .exe</a> </li> <li> <strong>Linux (Snap):</strong> <code>sudo snap install localpdf-studio</code> </li> <li> <strong>Linux (.AppImage):</strong> <a href="https://alinur1.github.io/LocalPDF_Studio_Website/" rel="noopener noreferrer">Download</a> </li> <li><p><strong>macOS (Intel):</strong> <a href="https://alinur1.github.io/LocalPDF_Studio_Website/" rel="noopener noreferrer">Download .dmg</a></p></li> <li><p><strong>GitHub:</strong> <a href="https://github.com/Alinur1/LocalPDF_Studio" rel="noopener noreferrer">github.com/Alinur1/LocalPDF_Studio</a></p></li> <li><p><strong>Website:</strong> <a href="https://alinur1.github.io/LocalPDF_Studio_Website/" rel="noopener noreferrer">alinur1.github.io/LocalPDF_Studio_Website</a></p></li> </ul> <h2> If this helps you </h2> <p>I'm not a company. I'm not monetizing your data. We're two students building this because privacy shouldn't be a premium feature.</p> <ul> <li> <strong>Star the repo</strong> on GitHub</li> <li> <strong>Share</strong> with someone who needs it</li> <li> <strong>Support on Patreon:</strong> <a href="https://www.patreon.com/cw/MdAlinurHossain" rel="noopener noreferrer">patreon.com/cw/MdAlinurHossain</a> </li> </ul> <h2> The bottom line </h2> <p>Your files should never have to leave your machine.</p> <p>That's not radical. That's how software used to work before the cloud convinced everyone to upload everything.</p> <p>LocalPDF Studio just brings that back. For PDFs.</p> <p>Try it. Audit it. Fork it. Share it.</p> <p><em>Licensed under AGPL-3.0. Free forever. No catch.</em></p> privacy opensource pdf ocr
