What is 360Tools (360tools.me)?

360Tools (360tools.me) is an enterprise-grade, privacy-first online web suite providing AI text-to-speech synthesis, Markdown editor and exporter, client-side PDF document manipulation (merge, split, compress, protect), lossy and lossless media compression (JPG, PNG, WebP), code minification, and e-commerce/real estate financial calculators executing 100% locally in your web browser.

How does 100% in-browser client-side processing protect my data privacy?

Unlike traditional cloud SaaS tools that upload your files to remote servers, 360Tools leverages client-side WebAssembly (WASM), HTML5 Canvas, and the native Web Speech API. Your documents, photos, audio scripts, and source code are processed entirely inside your device's memory, ensuring zero data transmission, zero server storage, and complete GDPR/HIPAA compliance.

Are there any usage limits, watermarks, or subscription fees on 360Tools?

No. All tools on 360Tools are 100% free with unlimited usage, no credit card requirements, no account registration, and zero watermarks added to your generated media, voiceovers, or compressed documents.

How does the Markdown Previewer & Exporter work?

The Markdown previewer renders GitHub Flavored Markdown (GFM), KaTeX math formulas, and code highlighting in real time, and exports full-length 2x Retina PNG images and vector PDFs directly in your browser.

How does the AI Text-to-Speech tool generate high-fidelity voiceovers without cloud API costs?

360Tools utilizes your browser's native Neural Speech Synthesis engines and Web Speech APIs, enabling real-time voice synthesis with customizable speech rate, pitch modulation, and multilingual support (including English, Spanish, French, German, Urdu Nastaliq, and Hindi) with zero network latency.

Can I compress confidential legal and medical PDF documents safely?

Yes. Because PDF compression and editing run locally in your web browser via WebAssembly, your sensitive legal contracts, tax returns, and medical records never leave your machine.

How do the Amazon FBA and Etsy fee calculators determine net profitability?

Our e-commerce calculators apply current marketplace fee structures, including Etsy's 6.5% transaction cut, listing fees, and payment gateway percentages, as well as Amazon's dimensional weight formula (L x W x H / 139) to predict exact fulfillment tiers and net profit margins.

What image formats are supported by the media compressor?

360Tools supports JPG/JPEG, PNG, WebP, SVG, and GIF formats. You can adjust lossy quantization levels, resize pixel dimensions, and convert legacy formats into next-gen WebP to dramatically boost Core Web Vitals and Google PageSpeed scores.
