Learn more about how our offline compress processes files secure and fast.
Our compressor works entirely inside your browser using HTML5 Canvas and native JS resamplers. Your images are never uploaded to any server, making the process 100% private and extremely fast.
We support major formats including JPEG/JPG, PNG, WEBP, and AVIF. You can adjust the quality slider to find the perfect balance between file size and visual details.
Because the compression happens locally on your device's hardware, there are no strict server-enforced limits. However, we recommend files under 50MB for the smoothest experience on mobile devices.
