What we offer
LightPic compresses, converts, crops and adds mosaic to images. LightDoc converts supported documents to Markdown. LightJSON formats, validates and edits JSON. LightPass generates random passwords on your device.
The tools listed above currently require no account, and their core processing runs locally in your browser. Each tool explains its supported formats and limits.
How we build tools
We prioritize processing on your device and clear actions, limits and results. The site supports Simplified Chinese, English, Spanish, Portuguese, French and German, with light and dark appearances.
Local processing does not mean the website makes no network requests. Our privacy policy describes analytics, local preferences, JSON drafts and the document tool’s offline cache.
Future features that need server processing will explain data submission and handling before use.
