Why this site exists
Most free online tools make you upload your file to their server, wait in a queue, and then add a watermark or ask for your email. That's slow, and it means strangers handle your contracts, ID photos and bank statements.
Here the work happens in your own browser. Compressing a photo, merging PDFs, making an invoice or working out a loan all happen on your device, so it's quick and private, and it keeps working if your connection drops after the page loads. You can check: open your browser's network tab and drop in a photo. Nothing goes out.
What runs where
- Images, PDFs, video, the voice changer, recorders and transcriber: on your device. Files never leave it.
- Text to Speech: the voices built into your device. It used to call a paid AI voice service, which never worked once (the API key was wrong the whole time), so now it uses the voices your phone or computer already has. Voices marked “online” are your browser's own cloud voices.
- Viral Hook Generator: your idea goes to Google Gemini to write the hooks; we don't keep it. The first Gemini model I tried kept answering “high demand”, so now it tries three before giving up.
- IP & DNS Lookup: on our server, because a browser can't look up DNS by itself. Nothing's stored.

How we keep it accurate
Calculators use standard published formulas (for example Mifflin-St Jeor for calories, the US Navy method for body fat and the standard amortization formula for loans), and every tool is tested automatically in a real browser before each release. Results are estimates for planning, not financial, medical, tax or legal advice.

Frequently asked questions
Is it really free?
Yes. Every tool is free with no account or watermark. The Viral Hook Generator has a fair-use limit of a few hooks every few minutes, because each one is written by an AI service.
How can it work without uploading my files?
Your browser is a powerful computer. The tools use open-source engines (FFmpeg for video, pdf.js and pdf-lib for PDFs, your browser's own image codecs) that run inside the page, on your device.
How is the site paid for?
Running tools in your browser costs us almost nothing. The site may show ads in the future, and some advanced AI features may become part of an optional paid plan.
Can I use the results commercially?
Yes. Files, invoices, barcodes and QR codes you make are yours to use for anything.
