I wanted one clean tool that works on a clean machine with zero setup.</p> <p><strong>What it does</strong></p> <ul> <li>Converts documents (PDF, DOCX, XLSX, PPTX, HTML, EPUB...), images (JPEG, PNG, WebP, HEIC, ICO...), audio (MP3, WAV, FLAC...) and video (MP4, MKV, MOV...)</li> <li>Batch conversions</li> <li>Multi-engine fallback if one engine fails, it tries the next automatically</li> <li>100% offline, no telemetry, no account</li> </ul> <p><strong>Some extras I'm proud of</strong></p> <ul> <li>Auto dark/light mode from the Windows registry</li> <li>Statistics dashboard with animated charts</li> <li>Achievements &amp; rank system backed by SQLite</li> <li>Project files (.fcproj) to save and reopen conversion setups</li> <li>Drag files directly onto the .exe to pre-load them</li> <li>Encrypted settings storage</li> </ul> <p>It's open source and completely free.</p> <p>Here is where you can find it or if you want to learn more:</p> <p><a href="https://github.com/Hyacinthe-primus/File_Converter_Pro" rel="noopener noreferrer">GitHub</a><br> <a href="https://hyacinthe-primus.itch.io/file-converter-pro" rel="noopener noreferrer">Itch.io</a></p> <p>I will be glad to hear your thoughts on it.<br> Thanks</p> productivity beginners python opensource
