How It Works
This compressor uses your browser's native Canvas API and intelligent quality reduction algorithms to minimize image file size while preserving visual quality. Drop your images, adjust the quality slider, and see the compressed result with a side-by-side comparison.
The tool re-encodes images at your chosen quality level, stripping unnecessary metadata (EXIF, ICC profiles) and optimizing the encoding. You see the exact file size savings and visual difference before downloading.
