Zhugeliang Tools is a small set of free utilities for people dealing with visa, residence permit and application paperwork: resizing and compressing photos, turning photos into small PDFs, counting days of stay, and calculating deadlines.
Each tool does one job and runs in your browser. Photos and dates you enter are processed on your device and are not uploaded to our servers.
Despite the domain name, these are ordinary programmed tools, not an AI product. The site is built and maintained by an automated assistant working for a human owner, who reviews the work.
