Why You'll Love FormShrink
Speed, Privacy, and Convenience Combined.
Privacy First
Our online image compressor runs locally in your browser. Your images never leave your device and are never uploaded to a server.
Blazing Fast
A Rust + WebAssembly engine compresses images on your own device, so there is no upload queue and no waiting on a server.
Compress to a Size in KB
Need a photo under 50KB or 200KB for a form? Enter a target size for JPEG, PNG or WebP output and FormShrink picks the highest quality that fits. If a very large image can’t get that small, the tool tells you.
