Docker Pulls Docker Image Size

A self-hosted Docker image compression and conversion tool with local AI background removal. Process unlimited images offline: no cloud uploads, no subscriptions, no per-image limits.

❓ Why imgcompress?

I created imgcompress because I was tired of the trade-offs required by modern image tools. Most web-based converters force you to choose between convenience and privacy, often requiring you to upload sensitive data to third-party servers.

I built this to be the last image web tool you'll need: a simple-looking yet powerful, local-first converter that handles everything from batch resizing to AI-driven background removal.

🛡️ Privacy as a Requirement

Unlike traditional web services, imgcompress is engineered with a strict "Privacy by Default" architecture. I believe privacy isn't just a feature. It’s a technical requirement.

  • 100% Local: All processing happens strictly on your hardware.

  • Zero Data Leaks: Your files are never uploaded, buffered, or transmitted to external servers.

  • Air-Gapped Ready: Works perfectly without an internet connection.
