As answered by people managing Optimaza and Opalstack.
Optimaza's answer
Optimaza processes images entirely in the browser. Files are never uploaded to a server, stored, or tracked.
Unlike most online image compressors, it focuses on privacy, simplicity, and speed — no accounts, no cloud processing, and no hidden data collection.
Optimaza's answer
Optimaza is ideal for users who care about privacy and control. Images are compressed locally on the device, which makes the tool faster and safer than upload-based alternatives.
It’s also lightweight and straightforward — open the page, drop images, compress, and download.
Optimaza's answer
Optimaza is built for developers, designers, marketers, and everyday users who need a fast way to optimize images.
It’s especially useful for people working with websites, emails, or content platforms who want smaller image files without sharing them with third-party servers.
Optimaza's answer
Optimaza started as a small side project to solve a simple problem: compressing images without uploading private files to random online services.
The goal was to create a clean, browser-based tool that respects user privacy while still delivering practical image optimization results.
Optimaza's answer
Optimaza is built using modern web technologies, including JavaScript, WebAssembly, and browser-native image processing APIs.
All compression happens client-side, without server-side image handling.
Optimaza's answer
Optimaza is currently used by individual developers, designers, small teams, and content creators around the world.
The product is still early-stage and growing organically.
