The Kitzit Documentation
Expert guides and technical insights on how we handle your data with absolute privacy.
Privacy & Security
🔒 End-to-End Local Processing
Most web tools use a "Cloud Model": you upload a file, their server processes it, and you download it back. Kitzit uses a "Local Model." Your files are never uploaded to a server. All calculations happen within your browser's temporary memory (RAM), meaning your data never leaves your device.
🛡️ No Databases, No Logs
Since we don't have servers processing your data, we have no reason to store it. Kitzit does not maintain a database of user files. Once you close the browser tab, the session is permanently wiped from your RAM.
The Technology
⚙️ Client-Side Binary Manipulation
We utilize high-performance JavaScript libraries to read the binary structure of files directly. Instead of sending data to a backend, our tools modify the file objects in real-time within the browser's memory space.
🖼️ Hardware-Accelerated Rendering
For tools that require visual previews, we leverage your device's GPU. This ensures that the visual representation you see is generated locally, eliminating the need for server-side image processing.
Processing Files
📄 Input & Sequencing
When using tools that combine multiple files, ensure they are uploaded in the desired order. Most of our tools allow for drag-and-drop reordering to ensure the final output is exactly as you intend.
📉 Compression & Optimization
Our optimization tools target redundant data and compress high-resolution assets. Note that if a file is already highly optimized or consists purely of text, the file size reduction may be minimal.
Security Tools
🎨 Visual Protection
For tools that add layers (like watermarks or overlays), we recommend subtle opacity settings for professionalism. Tiled modes are available for high-security documents to ensure protection across the entire page.
🔐 Handling Encrypted Files
Kitzit tools operate on decrypted data. If your file is password-protected, you must unlock it using your local system software and save an unlocked copy before processing it through our studio.
File Management
✂️ Precise Extraction
Our extraction tools allow for specific range selection. This allows you to carve out only the necessary data from a larger file, creating a new, clean version of the document without remnants of the original.
🗑️ Permanent Removal
When removing data or pages, Kitzit generates a brand new file containing only the preserved elements. This ensures that deleted information is not just "hidden" but completely absent from the new file structure.
Common Questions
💰 Is this service really free?
Yes. Kitzit is a passion project dedicated to digital privacy. We avoid subscriptions and paywalls. We support the site through modest advertising, which allows us to keep the tools free for everyone.
🚀 Do I need to create an account?
No. Accounts are just another way to collect data. Kitzit requires zero registration. Just upload, process, and download.
Limits & Compatibility
💻 Browser Requirements
Since we use advanced Web APIs, we recommend the latest versions of Chrome, Firefox, Edge, or Safari. Legacy browsers are not supported due to their lack of binary processing capabilities.
📦 File Size Constraints
Because processing happens in your RAM, the limit is your device's hardware. Most modern computers can handle files up to 500MB easily. For exceptionally large files, we recommend splitting them into smaller chunks first.
