Local-first browser tools — privacy workflow

A practical guide to Tentaco tools that process files and text in your browser instead of uploading to cloud converters.

Many “free online tools” monetize uploads. Tentaco’s local-first defaults keep standard PDF, JSON, image and password workflows on-device.

This guide maps common tasks to privacy-friendly landings so you can replace upload-heavy habits.

Kroky

Prefer /use landings that state local processing for your file type (PDF, images, JSON).
Avoid pasting production secrets into any tool — redact samples when possible.
Download results immediately and close the tab when finished.
For e-invoices and contracts, keep retention and access control on your side.
