Frequently asked
questions
For JPEG output, compression is lossy — quality is reduced to achieve smaller file sizes. For PNG output the file is re-encoded by the browser canvas which may slightly reduce size, but for true lossless PNG compression you'd need a server-side tool. Converting a PNG to JPEG at high quality typically achieves the biggest size reduction.
For photos on the web, 75–85% quality usually offers the best balance between visual quality and file size. For thumbnails or images where fine detail is less important, 60–70% works well. You can compare the side-by-side preview to judge.
No. The entire compression process happens in your browser using the HTML5 Canvas API. Your image never leaves your device.
