Free tools that run in your browser

Free tools for everyday files, images, and text

Use RuMystic without creating an account or paying a fee. Fix images, remove portrait backgrounds, read text from pictures, check text before sharing it, format JSON, or try local AI tools directly in your browser.

• Images and documents: upscale or repair photos, remove portrait backgrounds, read text, and inspect document layouts.
• Text and data: check sensitive details before sharing, review English feedback, and format or validate JSON.
• Local AI and creation: test browser AI support, run ONNX experiments, and turn text into a 3D model.

How it works

• Choose a tool, add text or a file, and download or copy the result when it is ready.
• Most tools work without a login or a usage quota. AI tools may download an open-source model the first time you use them.
• Some AI tasks need a modern browser and enough device memory; each tool explains its limits before it runs.

Your files stay on your device

• Core processing happens in the browser on your computer. Your files and input text are not sent to our processing server.
• When a tool needs an AI model, the browser may download that model, but it does not upload your source file or pasted text for processing.
• Automation can make mistakes. Check important results, especially sensitive-data detections, OCR text, and AI-generated output.
