Frequently Asked Questions

WebP is a modern image format developed by Google that provides superior compression. WebP images are typically 25-35% smaller than equivalent JPEG or PNG files at the same visual quality. All major browsers support WebP, making it the recommended format for web performance.

No. All image processing happens entirely in your browser using the HTML5 Canvas API. Your images never leave your device, are never sent to any server, and are never stored anywhere. This makes the tool safe for confidential screenshots and private photos.

For most web images, a quality setting of 75-85% provides significant file size reduction with minimal visible quality loss. Below 60%, compression artifacts become noticeable. PNG output is lossless regardless of the slider. Use the preview to compare before downloading.

You can upload PNG, JPG/JPEG, GIF, BMP, SVG, and WebP images. Output formats include WebP (best compression), JPEG (universal compatibility), and PNG (lossless with transparency). SVG inputs are rasterized during conversion.
