Private image optimization in the browser
This compressor uses the browser canvas to resize and encode images locally. It is useful for reducing photo size before uploading to websites, email, forms, ecommerce listings, and social profiles without sending the original file to a server.
Questions
Are my images uploaded?
No. Compression runs inside your browser, so selected images stay on your device.
Which output format should I choose?
WebP usually gives the smallest file, JPG is best for photos and broad compatibility, and PNG is best when you need sharp graphics or transparency.
Can I resize and compress at the same time?
Yes. Set max width or height and choose a quality level before downloading the optimized image.
