Our Philosophy

Fast optimization shouldn't cost you your privacy.

Most online image compressors upload your personal photos to their servers, process them, and store them temporarily—or sometimes permanently. We thought that was a broken system.

Foto Compressor was built by developers who believe in a "Zero-Upload" web. By leveraging modern WebAssembly and the Canvas API, we moved the heavy lifting from the server directly into your browser.

Frequently Asked Questions

Everything you need to know about our AI compression engine.

Are my images uploaded to your server?

No. Unlike other tools, Foto Compressor processes images 100% locally in your browser using the Canvas API. Your data never leaves your computer.

What is the best format for web speed?

We recommend WebP. It offers superior lossless and lossy compression for images on the web, often reducing file size by over 30% compared to JPEG.

Does compression reduce image quality?

Our AI-driven algorithm targets redundant pixel data. At 80% quality, most users cannot see a visual difference, but the file size is drastically smaller.

How many images can I process at once?

You can batch-process up to 50 images at a time. This limit ensures your browser remains stable and fast during heavy hardware-accelerated tasks.
