Features of Image Compressor
What is Image Compressor?
The Image Compressor is a web performance optimization tool utilizing smart lossy compression algorithms. It aggressively reduces the data footprint (bytes) of your images while carefully preserving the visual fidelity and sharpness perceived by the human eye.
When to use?
- Web Developers shrinking banner and product images to improve Google PageSpeed scores
- Photographers reducing massive high-res photos to fit within Email attachment limits
- Smartphone users freeing up local device storage by compressing their heavy image galleries
Frequently Asked Questions
Will compression make my image look blurry or pixelated?
It depends entirely on the "Quality" setting you choose. At our default optimization level (around 80%), the algorithm selectively strips out color spectra that the human eye cannot perceive, resulting in up to 80% smaller file sizes with nearly identical visual quality.
Why did my PNG file get LARGER after compressing it?
If your PNG is extremely simple (like a flat two-color logo) and already highly optimized, running it through additional compression routines might append structural metadata that actually increases the file size. In such rare cases, keep your original file.
Are my personal photos uploaded to a cloud server?
Absolutely not! All image processing happens locally inside your browser using HTML5 Canvas and JavaScript algorithms. Your files are never uploaded to any remote server, guaranteeing 100% data privacy.
