Frequently Asked Questions
Everything you need to know about MixtureTool tools, client-side zero-storage privacy, supported formats, and performance.
What makes MixtureTool different from other online tool websites?
Most online conversion and calculation websites upload your confidential text and files to remote cloud servers to process them. MixtureTool is engineered differently: all operations execute locally in your web browser using modern JavaScript, HTML5 Canvas, and Web APIs. Your content never leaves your machine.
Who operates and maintains MixtureTool?
MixtureTool was built and is independently maintained by Jack Son, an enthusiast frontend engineer and designer dedicated to creating fast, private, and accessible web experiences. Learn more on our About Us page.
Are my uploaded files, images, or text stored anywhere?
Never. MixtureTool does not possess a backend server that receives or stores user inputs. All text transformations (like in the Word Counter and Case Converter) and file operations (like the Image Resizer) occur purely within your computer's local RAM. Read our full Privacy Policy for details.
Does MixtureTool use cookies or track personal data?
MixtureTool uses first-party browser local storage solely to remember user preferences (such as unit preferences or dark/light system options). We do not collect or sell personally identifiable information. Standard server log files may record basic connection data (IP address, browser type) purely for operational network health.
What file formats and file size limits are supported?
Our file utilities support standard web graphics: Image Resizer and Image Compressor support PNG, JPEG, and WebP up to 25 MB. Image to Base64 supports PNG, JPG, GIF, WebP, and SVG up to 10 MB. SVG Optimizer supports standard XML-based SVG files up to 5 MB.
How does client-side image compression work without a server?
When you select a picture, your browser reads the raw binary data into an in-memory HTML5 <canvas> element. The browser native hardware-accelerated 2D rendering engine applies bicubic resampling and compression, converting the canvas directly into a local blob using canvas.toBlob().
Is the SVG Optimizer safe from embedded malicious scripts?
Yes. In the SVG Optimizer, previews are rendered safely using sandboxed image data URIs rather than raw DOM injection, preventing pasted vector scripts or event handlers from executing in your browser context.
Can I use MixtureTool offline or on intermittent connections?
Yes. Once a tool page finishes loading into your browser tab, all computations (calculations, text manipulations, hashes, conversions) run on your local processor and do not require active network roundtrips.
How does the JSON Formatter detect syntax errors?
The JSON Formatter runs browser-native JSON parsing engines with syntax boundary detection. If an error is detected, it highlights the exact unexpected token and position for immediate debugging.
Does the Color Converter support 3-digit shorthand hex codes?
Yes! In both the Color Converter and Contrast Checker, entering shorthand like #f00 or #fff automatically normalizes and expands to full 6-digit hex and corresponding RGB/HSL values.
Are the BMI Calculator classifications suitable as medical advice?
No. The BMI Calculator provides generalized screening metrics based on World Health Organization formulas for adults. It does not measure body fat percentage, muscular mass, or overall cardiovascular health. Please consult a licensed medical physician.
How can I request a new tool or report an issue?
You can submit tool suggestions, feature requests, or issue tickets via our GitHub repository or contact Jack Son directly by email at [email protected].
