Privacy & Security
Is my data safe?

Do you store my files?
No, we never store your files. All processing happens locally on your device. Once you close the browser tab, all data is automatically cleared from memory.
Can I use SuperTool offline?

Tool-Specific Questions
What file formats are supported?
Different tools support different formats:
- Image Tools: JPG, PNG, WebP, GIF
- PDF Tools: PDF files
- Text Tools: Plain text, JSON, Base64
Is there a file size limit?
File size limits depend on your device's memory and browser capabilities. Generally, files up to 50-100MB work well. Very large files may take longer to process or may not work on devices with limited memory.
Can I process multiple files at once?
Yes! Tools like Image to PDF Converter and Image Compressor support batch processing. You can upload and process multiple files simultaneously.
Why is my PDF/image quality reduced after compression?
Compression reduces file size by removing some data. Our tools are optimized to maintain good quality while reducing size. You can adjust compression settings to balance between file size and quality.
How accurate are the calculators?
Our EMI Calculator and Rent vs Buy Calculator use standard financial formulas and provide accurate estimates. However, actual results may vary based on specific terms, fees, and conditions from lenders or landlords.
