What makes it different: <strong>your files never leave your browser.</strong></p> <p>🔗 <a href="https://trytoolhive.com" rel="noopener noreferrer">https://trytoolhive.com</a></p> <h2> Why I built it </h2> <p>Every time I needed to merge a PDF, compress an image, or trim a video, I'd end up on some sketchy site that wanted me to:</p> <ul> <li>Upload my private files to their server</li> <li>Wait in a queue</li> <li>Watch ads</li> <li>Sometimes pay, sometimes create an account</li> <li>Trust them to delete the file (they don't)</li> </ul> <p>I wanted one clean place where everything just… works. Locally. Instantly. Free.</p> <h2> What's inside </h2> <ul> <li> <strong>PDF tools</strong> — merge, split, compress, convert, edit, unlock, watermark</li> <li> <strong>Image tools</strong> — convert, compress, resize, crop, background remover, upscaler</li> <li> <strong>Video tools</strong> — trim, compress, convert, extract audio, GIF maker</li> <li> <strong>Audio tools</strong> — MP3 cutter, converter, text-to-speech, speech-to-text</li> <li> <strong>Developer tools</strong> — JWT decoder, JSON formatter, regex tester, base64, hash</li> <li> <strong>Generators</strong> — QR codes, passwords, invoices, resumes, signatures</li> <li> <strong>Calculators</strong> — BMI, loan, mortgage, age, unit converter</li> <li> <strong>And more</strong> — 3D converters, design tools, text utilities</li> </ul> <p>All <strong>119+ tools</strong> in one place. No signup. No upload. No limits.</p> <h2> The privacy bit </h2> <p>Because everything runs in your browser, none of your files ever touch a server. That means:</p> <ul> <li>📁 Your PDFs stay yours</li> <li>🖼️ Your photos don't get scanned</li> <li>🎥 Your videos don't get leaked</li> <li>🔒 No account, no history, no tracking of content</li> </ul> <p>It also means <strong>it keeps working offline</strong> after the first visit.</p> <h2> It's localized in 13 languages </h2> <p>English, Spanish, French, German, Arabic, Portuguese, Italian, Hindi, Bengali, Chinese, Korean, Japanese, and Russian. RTL supported for Arabic.</p> <h2> Try it </h2> <p>👉 <a href="https://trytoolhive.com" rel="noopener noreferrer">https://trytoolhive.com</a></p> <p>If there's a tool you use daily that's missing, drop it in the comments — I'm adding new ones every week. Honest feedback welcome, especially the harsh kind. 🙏</p> ai webdev programming productivity
