Frequently Asked Questions
Will compressing images reduce their quality?
Our smart compression algorithm minimizes quality loss while dramatically reducing file size. At 80% quality, most images retain visual clarity indistinguishable from the original to the human eye. You can adjust the quality slider to find your preferred balance between size and quality.
Is my data safe when using this tool?
Absolutely! All image processing happens entirely within your browser using client-side JavaScript. Your images are never uploaded to any server, ensuring complete privacy and security. Once you close the page, all data is automatically cleared from your browser.
What image formats are supported?
Our compressor supports JPG/JPEG, PNG, and WebP formats for both input and output. WebP typically offers the best compression ratios, while PNG preserves transparency. JPEG is ideal for photographs and general use where transparency isn't needed.
