Toolzyo is architected using native modern Web APIs such as the HTML5 Canvas API, Web Audio API, Web Cryptography API (SubtleCrypto), and client-side JavaScript Web Workers. When you upload an image, PDF, or text file, your web browser parses and processes the binary data entirely in local memory (RAM). The data never crosses the network, is never uploaded to any remote server, and is never logged or stored in external databases. You can verify this independently by opening your browser’s Network Developer Tools (F12) while using any tool on the site.

Yes. Most of our tools process files directly in your browser using client-side JavaScript — your files never leave your device. For tools that require server processing, files are automatically deleted within 1 hour after processing. We never access, read, or store the contents of your files. Read our Privacy Policy for full details.

We collect minimal data — basic analytics (anonymous page views, browser type) and any information you voluntarily provide (e.g., contact form submissions, newsletter signups). We never sell or share personal data. See our Privacy Policy for complete details.

Yes. Toolzyo uses HTTPS encryption across the entire website. All data transmitted between your browser and our servers is encrypted using TLS/SSL, ensuring your information is protected during transit.

File size limits vary by tool. Browser-based tools generally support files up to 50-100MB depending on your device’s memory. Server-side tools typically support files up to 25-50MB. Each tool page displays its specific file size limit.

No. Unlike many competitors, Toolzyo has no daily, hourly, or monthly usage limits. You can use as many tools as often as you need without any restrictions.

Toolzyo works with all modern browsers including Google Chrome, Mozilla Firefox, Microsoft Edge, Safari, Opera, and Brave. We recommend using the latest browser version for the best experience. Some advanced tools may have limited functionality in older browsers.

Yes! Toolzyo is fully responsive and works on smartphones, tablets, and desktop computers. Our tools are optimized for touch interactions and smaller screens. You can use them on any device with a modern web browser.

Tools that process files entirely in your browser (client-side) may work offline once the page is loaded. However, most tools require an internet connection for initial loading. Server-side tools always require an internet connection.

Yes. Because Toolzyo relies on zero server-side processing, once a tool page is loaded into your web browser, the underlying JavaScript and CSS assets are fully cached in your local browser cache. You can disconnect your network connection, work aboard an airplane, or operate within an air-gapped corporate intranet, and the calculation, conversion, and formatting features will continue to execute seamlessly.

Yes. You are free to use Toolzyo for both personal and commercial purposes. Files processed through our tools (converted PDFs, compressed images, generated QR codes, etc.) are yours to use however you wish. We make no claim of ownership over your content.

Yes, absolutely. Any barcodes, QR codes, SVG icons, formatted code, legal policy drafts, or calculated spreadsheets you generate using Toolzyo are 100% your intellectual property. You may use, publish, sell, or integrate all outputs freely into commercial client deliverables, retail product packaging, software codebases, and marketing materials without royalty fees or mandatory attribution.
