🗜️ Compress
Image Compressor
Reduce file size up to 90% with barely noticeable quality loss. 100% client-side — your images never leave your browser.
How does it work?
This tool uses your browser's built-in Canvas API to re-encode images at a lower quality level. All processing happens locally on your device — no files are ever uploaded to any server. This means it's both extremely fast and 100% private.
Pro tip: For photos, use JPG at 70-80% quality for the best size-to-quality ratio. For images with transparency or sharp edges, use PNG. For web images, WebP gives the smallest file size.
