About LeConvert
LeConvert is a free collection of 40+ browser-based tools built around one simple idea: your files should never have to leave your device to be converted, edited or analyzed. Every tool on this site — from image conversion to CAD-grade 3D processing — runs entirely inside your browser using modern web technology (WebAssembly, WebGL and the Web Audio API). Nothing is uploaded, nothing is stored, and there are no accounts.
Why we built it
Most "free online converters" upload your files to a server, keep them for an unknown time, limit file sizes, and bury the download behind pop-ups. We wanted the opposite: instant, private, unlimited tools that respect the person using them. Because processing happens on your own device, LeConvert has no file-size games, no queues, and no privacy trade-offs — a passport photo, a bank statement or a proprietary CAD model is never seen by us or anyone else.
What makes it different
Alongside everyday utilities (image ⇄ PDF, QR codes, OCR, invoices, calculators), LeConvert includes professional 3D tools rarely found in a browser: a STEP → GLB converter that tessellates real CAD geometry, a 3D model optimizer with Draco compression for game-ready assets, a GLB → USDZ converter for iPhone AR, and a 3D print estimator that calculates material cost and print time from a model file. These come from our background in 3D pipelines and product visualization.
How it stays free
The site is supported by unobtrusive advertising. Because the tools run on your device rather than expensive servers, we can keep everything free without sign-ups, subscriptions or artificial limits. Optional AI features (in the text tools) use your own API key, so they cost us — and you — nothing unless you choose to connect one.

📜 Terms of Use
LeConvert provides free browser-based conversion and creation tools. By using this site you agree to the following:
1. Free service. All tools are provided free of charge, "as is", without warranty of any kind.
2. Your files. Conversions run in your browser. Files are not uploaded to or stored on our servers. Any temporary server-side processing (where used) deletes files within minutes.
3. Your responsibility. You are responsible for the content you process and for complying with copyright and local laws. Don't use the tools for unlawful content.
4. Educational estimates. Health, financial, 3D-print and similar calculators provide general estimates for information only — not professional, medical, legal or financial advice.
5. Accuracy. We work hard for accuracy but cannot guarantee results are error-free. Verify important outputs independently.
6. Ads. This site is supported by advertising. We don't control individual ad content shown by our ad partners.
7. Changes. These terms may be updated at any time. Continued use means acceptance.

🔒 Privacy Policy
Your privacy matters. This is a simple, honest summary of how LeConvert handles data.
1. Your files stay on your device. Image, video, PDF, 3D and other conversions are processed entirely in your browser. We do not see, upload, or store your files.
2. No accounts. We don't require sign-up and don't collect names, emails or passwords. If you email feedback, we only see what you choose to send.
3. Cookies & ads. We use advertising (e.g. Google AdSense). Ad partners may use cookies to show relevant ads and measure performance. You can manage ad personalization in your Google account settings or browser.
4. Analytics. We may use privacy-respecting analytics to count visits and improve the tools. This does not identify you personally.
5. Optional online voices/APIs. A few features (e.g. some text-to-speech voices, currency rates) may call third-party services to function. These only run when you use that specific tool.
6. Children. The tools are general-purpose; calculators and health tools are educational only and not directed at children.
7. Contact. Privacy questions? Email lemeservice9@gmail.com.
