Why Use Our Image Compressor?
Large images slow down websites, eat up storage, and take forever to email. Our compressor runs entirely in your browser — your photos never leave your device. It supports JPEG, PNG, WebP, and GIF with configurable quality and resolution limits.
Frequently Asked Questions
How much will my image shrink? Typically 40-80% depending on the original format and your quality setting. JPEGs compress well at 70-80% quality.
Does compression reduce image dimensions? Only if you set a max width lower than the original. Quality compression reduces file size without changing dimensions.
Are my images uploaded? No. All processing happens in your browser using Web Workers.
