Frequently Asked Questions
Find answers to common questions about SwifTools, our free online tools, privacy practices, and usage guidelines.
Getting Started
What is SwifTools?
SwifTools is a free online toolkit offering 20+ tools for developers and everyday users. Our tools include JSON formatters, calculators, converters, password generators, and more. All tools work directly in your browser with no registration required.
Are all tools really free?
Yes, all tools on SwifTools are completely free to use with no hidden costs, usage limits, or premium tiers. We cover our operational costs through non-intrusive ads that respect your experience.
Do I need to create an account?
No, all tools are immediately accessible. Simply visit any tool page and start using it. No registration, no email, no password required.
What browsers are supported?
SwifTools works on all modern browsers including Chrome, Firefox, Safari, Edge, and Opera. For the best experience, we recommend using the latest version of your browser.
Privacy & Security
Is my data safe?
Absolutely. Most tools on SwifTools process your data locally in your browser. This means your data never leaves your device and is never sent to our servers. For example, when you use our password generator, the password is created on your computer and never transmitted anywhere.
Do you store my data?
We do not store, collect, or log any data you process through our tools. Your inputs and outputs are processed entirely in your browser's memory and are cleared when you close or refresh the page.
How does image compression work?
Our image compressor uses browser-based processing. Your images are compressed locally using Canvas API - they are never uploaded to any server. This ensures complete privacy while still achieving excellent compression results.
Can my passwords be intercepted?
No. Our password generator uses your browser's cryptographically secure random number generator (crypto.getRandomValues()). Passwords are generated entirely on your device and never transmitted over the network.
Is HTTPS encryption used?
Yes, our entire website is served over HTTPS with TLS 1.3 encryption. This ensures that all data transmitted between your browser and our servers is encrypted and secure.
Tool Usage
What file formats are supported?
Our image compressor supports JPG/JPEG, PNG, WebP, and GIF formats. JSON formatter supports all valid JSON input. URL encoder/decoder works with any URL or text. Most tools support common formats that work across all browsers.
Is there a maximum file size?
There are no strict limits, but for optimal performance, we recommend keeping files under 10MB for image compression and 1MB for text-based tools. Larger files may take longer to process in the browser.
Can I use tools on mobile devices?
Yes, all SwifTools are fully responsive and work on smartphones and tablets. The interface automatically adapts to smaller screens, making it easy to use tools on any device.
How accurate are the calculators?
Our calculators are designed for accuracy and use standard formulas. BMI uses the standard WHO formula, mortgage calculations use standard amortization formulas, and all financial calculators follow industry-standard calculations. For medical or financial decisions, please consult a professional.
How do I report a bug or request a feature?
We welcome feedback! You can reach us via the contact information on our About page. When reporting bugs, please include the tool name, your browser version, and a description of the issue. We review all feedback and prioritize based on user demand.
