Frequently Asked Questions

Where are my photos or graphics processed? +

Your images are processed 100% locally on your device using your browser's HTML5 Canvas engine. No images are ever sent over the internet or saved to our servers.

Which format provides the smallest file size for web pages? +

WebP almost always yields the highest compression efficiency with exceptional image sharpness, typically saving 25-35% more space than standard JPEG.

What is the recommended quality setting for web graphics? +

A quality setting between 75% and 85% delivers the best balance of imperceptible quality loss and drastic file size reduction (often saving 60% to 80% of bandwidth).

Can I resize dimensions at the same time as compressing? +

Yes. Use the "Max Width" slider to downscale high-resolution camera photos (e.g. 4000px down to 1400px), which dramatically shrinks the file weight.
