알아둘 점
Images stay on your device. PNG compression cannot use a quality slider, so very detailed or transparent PNGs may not reach extremely small targets.
자주 묻는 질문
Are my images uploaded?
No. Decoding, resizing and encoding happen in your browser. Files, names and metadata are never sent to BrightTools.
Can I compress multiple images?
Yes. Select or drop multiple files, review the queue, then use Compress All. Processing is sequential to keep mobile browsers responsive.
Can I compress an image below 200KB?
Choose a smaller target such as 100 KB. The tool searches quality and then reduces dimensions when necessary.
Does compression reduce image quality?
Lower JPEG and WebP sizes require lower quality or dimensions. The tool chooses the highest quality that fits your target and never silently replaces an image with a larger file.
Why can’t a PNG reach the target size?
PNG is lossless and its size depends on image detail. We preserve the format and transparency and explain when the target is not realistic.
Can I download all images as a ZIP?
Yes. After successful processing, Download All as ZIP creates the archive entirely in your browser.
