Your files stay on your device.

These tools read selected files into browser memory. There is no file-upload API, account, analytics script, advertising script, payment service or persistent file storage in this version. Processing libraries are served from this site. Loading the website still sends ordinary HTTP requests to the host, which may log connection information.

The light/dark theme preference is saved in browser localStorage when available. File contents are not saved there. Closing or reloading a tool clears its working state. Downloads remain on your device. Processing is limited by your browser and device memory; we do not promise unlimited file sizes. Default upload limit: 25 MB per file, with additional batch limits in each tool.

Notebook cleaning leaves source code and Markdown untouched. PDF cropping hides content rather than deleting it; image covers and PDF annotations are not secure redaction. Drawn signatures are visual marks, not certificate-backed signatures. Check exported documents before using them.

Little Tools is an experimental utility website hosted on Cloudflare Pages. These tools are provided as-is; verify exported files before relying on them. They are not an authoritative legal, financial or document-integrity service.
