Supports JPG, PNG, WebP — multiple files allowed
How Does Image Compression Work?
Our image compressor uses industry-grade WebAssembly (WASM) engines compiled from native C libraries — MozJPEG for JPG, libwebp for WebP, and libimagequant (the same engine behind TinyPNG) for PNG. PNG compression uses perceptual color quantization, reducing file size by 60–80% while keeping the image visually identical. All processing runs locally in your browser — your images never leave your device.

Frequently Asked Questions
Is this really free?
Yes, completely free with no limits. Compress as many images as you want.
Will compression reduce image quality?
You control the quality level with a slider. At 80% quality, most images look identical to the original while being significantly smaller.
What formats are supported?
We support JPG/JPEG, PNG, and WebP. You can also convert between formats during compression.
Is there a file size limit?
Since everything runs in your browser, there's no server-side limit. Very large images (50MB+) may be slower to process depending on your device.
