Answers to common questions about our fast browser-based image compressor.
No. All compression processes run locally in your browser using HTML5 OffscreenCanvas and Web Workers. Your data remains entirely private and never leaves your computer.
We support JPEGs/JPGs, PNGs, WEBP, and AVIF images up to 50MB.
Target Size mode runs a smart search algorithm that dynamically fits the quality and dimension scales of your image to fit precisely under your designated size threshold.
When compressing PNGs or converting to WEBP/AVIF, transparency is preserved natively. For JPEG conversions (which do not support transparency), transparent zones are filled with a clean white background.
