Who we are
Image Compressor is a privacy-first web application developed by ecn-apps. We build small utilities that are fast, predictable and respect user data — this tool compresses images entirely in your browser so your files never leave your device.
Our mission
We want to make the web faster and more accessible by offering practical tools that anyone can run locally. Reducing image size is one of the highest-impact ways to improve load times and lower bandwidth costs.
Team & acknowledgements
The project is maintained by a small team at ecn-apps and contributors from the open-source community. Contributors help with code, translations and bug reports — see the repository for a full list of contributors.
How it works (brief)
Uploaded images are processed client-side using an in-browser pipeline: images are decoded into a canvas, optimized (binary-search quality for perceptual similarity), and re-encoded as WebP for smaller size. Compression can run inside a Web Worker for a responsive UI.
Typical results
Actual results vary by image type. Examples from typical runs:
- Landscape photo (5 MB) → 700–900 KB (~80–86% reduction)
- Portrait (2.5 MB) → 350–550 KB (~78–86% reduction)
- Screenshots / UI assets (1.2 MB) → 120–220 KB (~80–90% reduction)
Performance & usage tips
- Resize large images before compressing if you don't need huge dimensions.
- Batch convert similar images together (same content type) for consistent results.
- Prefer WebP or modern formats for best size-vs-quality trade-offs.
- Test with a representative sample — visual inspection matters more than raw bytes.
Roadmap
Planned work includes improved heuristics for photographic vs. graphical images, optional downscaling presets, and tighter integration with translation/community contributions. Feature requests are tracked in the project's issue tracker.
Contribute & support
Contributions are welcome: code, translations, documentation and issue reports help a lot. The fastest way to help is to submit a pull request with a language file (see translations/) or open an issue describing your suggestion.

Quick FAQ
- Will my image quality be affected?
- We use perceptual optimization to reduce file size while keeping visible quality high. You can always compare originals and adjust quality settings.
- Can I use this offline?
- Yes — once cached by your browser and the service worker, the app can run offline for repeated use.
