Frequently Asked Questions
Frequently asked questions about Zoomix's browser image optimizer.
Our tool utilizes the HTML Canvas API and standard browser encoders (`HTMLCanvasElement.toBlob`) to re-render and compress your images directly on your machine. This runs 100% locally and instantly.
No. Your images are loaded into your local browser memory and processed directly by your graphics processor/CPU. Zero bytes are uploaded to our servers, keeping your private pictures entirely safe.
Yes. PNG is a lossless format, so quality sliders will have minimal effect if you export back to PNG. However, if you convert your PNG to WebP or JPEG formats using our output selector, you will achieve up to 80-90% file size reductions.
