Our Story
Efisapp began in 2023 when a small team of developers found themselves repeatedly building the same utilities for different projects. They realized that many developers faced similar challenges: converting image formats, formatting code, and performing routine conversions.
Instead of keeping these tools internal, they decided to make them available to everyone. The founding principle was simple: create high-quality, browser-based tools that respect user privacy by processing everything client-side.
What started as a small collection of utilities has grown into a comprehensive platform used by thousands of developers, designers, and content creators worldwide. Today, Efisapp continues to expand its toolkit based on community feedback and emerging needs in the development landscape.

Our Privacy Commitment
We take your privacy seriously. All of our tools process data directly in your browser, which means your files never leave your device. We don't track your usage, collect personal information, or store any of your data on our servers.
This client-side approach not only protects your privacy but also allows our tools to work offline and process files faster since there's no upload/download time. It's a win-win for security and performance.
