We read everything that comes in. The fastest way to a fix is a message that includes the tool name, what you expected, and what actually happened.
Write to hello@lanrensoft.cn and you will usually get a reply within two business days.
What to include in a bug report
- The page you were on (e.g. Image Compressor).
- Your browser and device (Chrome on Windows, Safari on iPhone…).
- What you did, what you expected, and what happened instead.
- For image tools: the file type and approximate size (no need to attach confidential files).
Feature requests
If a tool would save you recurring minutes, tell us why you need it — recurring-use cases are the ones we build. We deliberately keep every tool simple, so niche enterprise requirements may politely be declined.
Business & partnership inquiries
For advertising questions, data-privacy clarifications or content licensing, use the same address with "Business" in the subject line.
